Can You Eat Weed? All You Need to Know About Marijuana Edibles
By Jillian Kubala, MS, RD
Marijuana — colloquially called weed — refers to the dried flowers, seeds, stems, and leaves of the Cannabis sativa or Cannabis indica plants (1).
It's a popular drug used by millions of people either for pleasure or to treat chronic health conditions.
Weed can be used in a number of ways, but some of the most popular methods include smoking and vaping.
However, some people wonder whether it's safe to eat marijuana and whether ingesting it has the same effects as smoking or vaping.
This article explains whether it's safe to eat weed and the health effects — both positive and negative — related to ingestion.
Can You Eat Marijuana?
The short answer is yes, you can eat weed. In fact, marijuana-infused foods and drinks have been consumed throughout history, as far back as 1000 B.C. (2Trusted Source).
Marijuana was used as medicine in ancient China and India and was introduced to Western medicine in the early 19th century. Edible applications, such as tinctures, were prescribed to treat various conditions, from chronic pain to digestive disorders (2Trusted Source, 3Trusted Source, 4Trusted Source).
Edible marijuana products were also used to relieve stress and induce euphoria, similar to alcohol.
Bhang, a beverage made from a mixture of the leaves and flowers of marijuana plants, has been consumed for centuries during religious festivals, such as Holi, a Hindu festival of love and color (3Trusted Source, 5Trusted Source).
In the United States, recreational use of edible marijuana products became popular during the 1960s, and today, many different types of edibles are available, both legally and illegally, depending on state laws.
For example, gummies, candies, chocolates, capsules, teas, and oils are some of the edible marijuana products sold in both legal marijuana dispensaries and through the illegal marijuana market.
Edibles enthusiasts also make their own weed products by infusing butter or oil with marijuana and mixing it into baked goods and other recipes.
Though you can eat raw weed, it won't have the same effect as consuming marijuana-based products, as marijuana has to go through a process known as decarboxylation to become activated (6Trusted Source).
Raw marijuana contains tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA), compounds that must be exposed to heat, such as in smoking or baking, to turn into the active forms, tetrahydrocannabinol (THC) and cannabidiol (CBD) (6Trusted Source).
Therefore, eating raw weed will not result in the same effects as consuming weed that has been heated, as in edible products like candies, tinctures, and baked goods.
Though you can't get high from eating raw weed, some health experts believe that eating it may offer some health benefits due to the wide array of plant compounds it contains.
Yet, research in this area is lacking, so the potential therapeutic benefit of raw marijuana is still unclear.
Weed has been consumed in various forms throughout history for both medicinal and recreational purposes. Though you can eat raw marijuana, it won't have the same effects as marijuana that has been heated.
Health Benefits Related to Edible Marijuana
Marijuana has many medicinal benefits and has been used to treat various ailments throughout history.
Today, edible marijuana products have a number of uses in the medical field and are becoming a more popular, accepted natural treatment in clinical settings.
May Benefit Certain Health Conditions
Edible marijuana products are often used to treat conditions, such as chronic pain, cancer-related symptoms, and anxiety.
Medical cannabis products can legally be prescribed in countries around the world, including Italy, Spain, Germany, and parts of the United States (7Trusted Source).
THC is one of over 100 active compounds — known as cannabinoids — in marijuana.
THC is the compound responsible for the psychoactive properties of marijuana products, including edibles, that may induce feelings of euphoria and relaxation (2Trusted Source).
Other compounds in marijuana, such as CBD, have been shown to have pain- and anxiety-reducing properties.
The powerful combination of therapeutic compounds in this plant makes it a popular natural treatment that effectively reduces symptoms of and eases pain related to various conditions.
Additionally, these products may significantly reduce pain and muscle spasms, relieve nausea and vomiting, enhance sleep quality, and improve depression and anxiety (9Trusted Source, 10Trusted Source, 11Trusted Source).
In fact, pharmaceutical companies manufacture oral preparations of marijuana-derived treatments, such as Sativex, which is an oral spray prescribed to treat pain and muscle spasticity (12Trusted Source).
Though edible marijuana products are prescribed and used to treat many other ailments, such as digestive and neurological disorders, high-quality research in these areas is lacking.
Therefore, the full therapeutic potential of marijuana is still unknown (13Trusted Source).
Edible marijuana is used to treat symptoms related to various medical conditions, such as cancer and chronic pain. However, high-quality studies are lacking, so the full effects of marijuana products on health are still unclear.
Potential Side Effects and Downsides of Eating Weed
Though edible marijuana products may benefit many conditions, some potential adverse effects may occur.
The main issue with edible marijuana products is that it can be very difficult to determine an appropriate dosage. Concentrations of THC vary widely depending on different factors, such as where the product was made and the quality of the marijuana used.
Additionally, unlike smoking weed, edible marijuana products have a long latency period, meaning it can take a while — sometimes hours — for it to take effect.
When marijuana is smoked, THC reaches the brain and takes effect within a few minutes. The effects peak at around 20–30 minutes after smoking and begin to wear off within 2–3 hours (10Trusted Source).
In contrast, the psychoactive effects of edibles usually take 30–90 minutes to kick in. The high feeling lasts much longer and typically peaks at about 2–4 hours after ingestion (10Trusted Source).
The effects of edibles can last for many hours, depending on how much was ingested, as well as your body weight, metabolism, gender, and other factors.
The combination of the highly variable THC concentration and the long latency period of edible marijuana products makes them very easy to unintentionally overconsume, which can lead to unwanted symptoms, such as paranoia and impaired motor ability.
Additionally, though rare, there have been instances of cannabis-induced psychosis, a condition usually related to overconsumption of edible marijuana products that results in symptoms like paranoid delusions, extreme sedation, hallucinations, and confusion (14Trusted Source).
Other side effects related to edible marijuana products include dry mouth, sleepiness, and changes in visual perception.
Another concern is that edible marijuana products often resemble regular candies, cookies, and other baked goods, posing a risk for children, pets, and other adults.
In fact, between 2005 and 2011, marijuana-related calls to U.S. poison control centers increased by 30% per year in states that decriminalized marijuana. Many of these calls were related to accidental ingestion of edible marijuana products (16Trusted Source).
Edible marijuana products are difficult to dose and take a long time to kick in. They also resemble regular food products, which may lead to accidental ingestion.
Is Eating Weed Safer Than Smoking It?
Though smoking weed is not often considered harmful, research has shown that inhaling marijuana smoke can negatively impact health, similar to cigarette smoke.
Both cigarette and marijuana smoke contain toxins, such as ammonia, hydrogen cyanide, and polycyclic aromatic hydrocarbons, that may damage your lungs and increase your cancer risk (17Trusted Source).
Yet, scientists emphasize that it's unclear whether or to what extent smoking marijuana influences cancer risk, as many available studies are of low quality, and confounding variables, such as cigarette smoking, affect study results (19Trusted Source).
In contrast, edible marijuana products have not been shown to negatively affect lung health or cancer risk.
Therefore, if you're concerned about the possible health risks associated with smoking weed, you may want to use edible marijuana products as an alternative.
However, because most marijuana research focuses on smoking weed, the long-term health implications of consuming edibles are still unknown.
Nevertheless, ingesting marijuana is likely safer than smoking it.
Marijuana smoke contains toxins that may negatively affect health. Though edibles are likely safer, the long-term health implications of these products are still unknown due to a lack of research.
How to Enjoy Edibles Safely (and Legally)
Many people enjoy using marijuana products to relax and ease stress, while some take edibles to treat or improve symptoms of a medical condition.
Either way, it's important to use safe products and choose appropriate dosages to avoid unwanted side effects.
If you're interested in using edibles to treat a medical condition, your healthcare provider is the best person to consult to learn if medical marijuana is an option.
Depending on where you live, you might be able to get a prescription. In the United States, 33 states allow the use of medical marijuana. It has also been legalized in countries around the world, including Italy and Australia (20Trusted Source, 21Trusted Source).
Some conditions that may warrant a medical marijuana prescription include chronic pain, anxiety, multiple sclerosis, terminal illness, and inflammatory bowel disease.
In contrast, recreational use of marijuana is illegal in many parts of the world, including most parts of the United States. Only 10 states, including California, Maine, Vermont, and Oregon, allow for the use of recreational marijuana products.
However, even though marijuana is legal to use in these states, it remains illegal at a federal level and is considered a Schedule I substance under the Controlled Substances Act (CSA).
According to the U.S. Drug Enforcement Administration (DEA), Schedule I substances are "determined to have a high potential for abuse" and are defined as having "no currently accepted medical use" (22).
Yet, many disagree with this classification, especially those who have seen firsthand that marijuana products offer powerful medicinal and therapeutic benefits for many people.
In fact, scientists have repeatedly questioned marijuana regulation, with some arguing that the current legal status is outdated and "thwarts legitimate research" exploring the potential of marijuana in the medical field (23Trusted Source, 24Trusted Source).
Though both social and political views on marijuana are changing rapidly, for now, citizens must abide by the laws set forth by state and federal governments for the use of both medical and recreational marijuana.
Purchasing Safe Marijuana Products
When using edible marijuana for the first time — whether for medical or recreational reasons — it's important to do so safely.
Sticking to prescribed dosage and usage recommendations can help reduce your risk of potential negative effects related to overconsumption.
If purchasing edible marijuana products in a state where recreational use is legal, only purchase products from a licensed dispensary that you trust.
Licensed dispensaries are often required to have their products tested for safety and potency in state-accredited laboratories to be approved for sale.
However, testing protocols vary considerably from state to state, and some don't require laboratory testing (25Trusted Source).
It's important to note that marijuana bought from illegal operations or dispensaries that sell untested products can be contaminated with pesticides, mold, fungi, bacteria, heavy metals, formaldehyde, and other substances, which can pose serious health risks (26Trusted Source).
Dispensaries typically carry a variety of marijuana products with different concentrations of THC and CBD, which can be confusing for first-time buyers. Consulting dispensary staff is a smart way to find the best product to suit your needs.
The legality of marijuana varies, so the use of both medical and recreational marijuana products depends on where you live. Only purchase marijuana products from trusted sources and follow dosing recommendations carefully.
The Bottom Line
Edible marijuana products may offer various benefits, including reducing symptoms of chronic illnesses and anxiety.
Still, these products may cause side effects, react with common medications, and take a long time to kick in.
Depending on where you live, you may be able to use medicinal or recreational products legally. However, it's important to only purchase from licensed, reputable dispensaries that sell products tested for purity and potency.

The coronavirus is certainly scary, but despite the constant reporting on total cases and a climbing death toll, the reality is that the vast majority of people who come down with COVID-19 survive it. Just as the number of cases grows, so does another number: those who have recovered.
In mid-March, the number of patients in the U.S. who had officially recovered from the virus was close to zero. That number is now in the tens of thousands and is climbing every day. But recovering from COVID-19 is more complicated than simply feeling better. Recovery involves biology, epidemiology and a little bit of bureaucracy too.
How does your body fight off COVID-19?<p>Once a person is exposed the coronavirus, the body starts producing <a href="https://www.mblintl.com/products/what-are-antibodies-mbli/" target="_blank">proteins called antibodies to fight the infection</a>. As these <a href="https://www.statnews.com/2020/03/27/serological-tests-reveal-immune-coronavirus/" target="_blank">antibodies start to successfully contain the virus</a> and keep it from replicating in the body, symptoms usually begin to lessen and you start to feel better. Eventually, if all goes well, your immune system will completely destroy all of the virus in your system. A person who was infected with and survived a virus with no long-term health effects or disabilities has "recovered."</p><p>On average, a person who is infected with SARS-CoV-2 will feel ill for about seven days from the onset of symptoms. Even after symptoms disappear, there still may be small amounts of the virus in a patient's system, and they should stay <a href="https://www.cdc.gov/coronavirus/2019-ncov/if-you-are-sick/steps-when-sick.html" target="_blank">isolated for an additional three days</a> to ensure they have truly <a href="https://health.usnews.com/conditions/articles/coronavirus-recovery-what-to-know" target="_blank">recovered and are no longer infectious</a>.</p>
What about immunity?<p>In general, once you have recovered from a viral infection, your body will keep cells called lymphocytes in your system. These cells "remember" viruses they've previously seen and can react quickly to fight them off again. If you are exposed to a virus you have already had, your antibodies will likely stop the virus before it starts causing symptoms. <a href="https://dx.doi.org/10.5114%2Fceji.2018.77390" target="_blank">You become immune</a>. This is the <a href="https://www.ncbi.nlm.nih.gov/books/NBK27158/" target="_blank">principle behind many vaccines</a>.</p><p>Unfortunately, immunity isn't perfect. For many viruses, like mumps, immunity can wane over time, leaving you <a href="https://www.sciencedaily.com/releases/2016/04/160421145747.htm" target="_blank">susceptible to the virus in the future</a>. This is why you need to get revaccinated – those "booster shots" – occasionally: to prompt your immune system to make more antibodies and memory cells.</p><p>Since this coronavirus is so new, scientists still don't know whether people who recover from COVID-19 are <a href="https://www.cdc.gov/coronavirus/2019-ncov/hcp/faq.html" target="_blank">immune to future infections of the virus</a>. Doctors are finding antibodies in ill and recovered patients, and <a href="https://www.cdc.gov/coronavirus/2019-ncov/hcp/clinical-guidance-management-patients.html" target="_blank">that indicates the development of immunity</a>. But the question remains how long that immunity will last. Other coronaviruses like <a href="https://doi.org/10.1002/jmv.25685" target="_blank">SARS and MERS produce an immune response</a> that will protect a person at least for a short time. I would suspect the same is true of SARS-CoV-2, but the research simply hasn't been done yet to say so definitively.</p>
Why have so few people officially recovered in the US?<p>This is a dangerous virus, so the Centers for Disease Control and Prevention is being extremely careful when deciding what it means to recover from COVID-19. Both medical and testing criteria must be met before a person is <a href="https://www.cdc.gov/coronavirus/2019-ncov/hcp/disposition-in-home-patients.html" target="_blank">officially declared recovered</a>.</p><p>Medically, a person must be fever-free without fever-reducing medications for three consecutive days. They must show an improvement in their other symptoms, including reduced coughing and shortness of breath. And it must be at least seven full days <a href="https://health.usnews.com/conditions/articles/coronavirus-recovery-what-to-know" target="_blank">since the symptoms began</a>.</p><p>In addition to those requirements, the CDC guidelines say that a person must test negative for the coronavirus twice, with the <a href="https://www.cdc.gov/coronavirus/2019-ncov/if-you-are-sick/care-for-someone.html" target="_blank">tests taken at least 24 hours apart</a>.</p><p>Only then, if both the symptom and testing conditions are met, is a person officially considered recovered by the CDC.</p><p>This second testing requirement is likely why there were so few official recovered cases in the U.S. until late March. Initially, there was a <a href="https://www.nytimes.com/2020/03/18/health/coronavirus-test-shortages-face-masks-swabs.html" target="_blank">massive shortage of testing in the U.S.</a> So while many people were certainly recovering over the last few weeks, this could not be officially confirmed. As the country enters the height of the pandemic in the coming weeks, focus is still on <a href="https://www.cdc.gov/coronavirus/2019-nCoV/hcp/clinical-criteria.html" target="_blank">testing those who are infected</a>, not those who have likely recovered.</p><p>Many more people are being tested now that states and private companies have begun <a href="https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/testing-in-us.html" target="_blank">producing and distributing tests</a>. As <a href="https://www.dispatch.com/news/20200406/coronavirus-in-ohio-from-its-rocky-start-testing-for-covid-19-slowly-ramping-up" target="_blank">the number of available tests increases</a> and the pandemic eventually slows in the country, more testing will be available for those who have appeared to recover. As people who have already recovered are tested, the appearance of any new infections will help researchers learn <a href="https://www.statnews.com/2020/03/24/we-need-smart-coronavirus-testing-not-just-more-testing/" target="_blank">how long immunity can be expected to last</a>.</p>
Once a person has recovered, what can they do?<p>Knowing whether or not people are immune to COVID-19 after they recover is going to determine what individuals, communities and society at large can do going forward. If scientists can show that recovered patients are immune to the coronavirus, then a person who has recovered could in theory <a href="https://www.vox.com/2020/3/30/21186822/immunity-to-covid-19-test-coronavirus-rt-pcr-antibody" target="_blank">help support the health care system</a> by caring for those who are infected.</p><p>Once communities pass the peak of the epidemic, the number of new infections will decline, while the number of <a href="https://www.newsweek.com/china-says-passed-peak-coronavirus-epidemic-covid-19-1491863" target="_blank">recovered people will increase</a>. As these trends continue, the risk of transmission will fall. Once the risk of transmission has fallen enough, community-level isolation and social distancing orders will begin to relax and businesses will start to reopen. Based on what other countries have gone through, it will be <a href="https://www.nature.com/articles/d41586-020-00154-w" target="_blank">months until the risk of transmission is low</a> in the U.S.</p><p>But before any of this can happen, the U.S. and the world need to make it through the peak of this pandemic. Social distancing works to slow the spread of infectious diseases and <a href="https://www.cdc.gov/coronavirus/2019-ncov/need-extra-precautions/what-you-can-do.html" target="_blank">is working for COVID-19</a>. Many people will <a href="https://www.yalemedicine.org/stories/2019-novel-coronavirus/" target="_blank">need medical help to recover</a>, and social distancing will slow this virus down and give people the best chance to do so.</p>

The future for the world's oceans often looks grim. Fisheries are set to collapse by 2048, according to one study, and 8 million tons of plastic pollute the ocean every year, causing considerable damage to delicate marine ecosystems. Yet a new study in Nature offers an alternative, and more optimistic view on the ocean's future: it asserts that the entire marine environment could be substantially rebuilt by 2050, if humanity is able to step up to the challenge.

Bread has been a source of basic nutrition for centuries, the holy trinity being wheat, maize and rice. It has also been the reason for a lot of innovation in science and technology, from millstones to microbiological investigations into a family of single-cell fungi called Saccharomyces.
Chemical leavening<p>If you like a little heft in your loaf, you will need a leavening agent.</p><p>For those short on time, you can use baking soda. That's a chemical compound of sodium bicarbonate mixed with potassium bitartrate, or cream of tartar.</p><p>Soda breads have their traditions in parts of eastern and central Europe, and in Ireland and Scotland, with Melrose loaves and "farls."</p><p>They can taste a bit bland, though, and are often considered only as an emergency solution on Sundays. No disrespect intended: They taste just fine fresh from the oven.</p><p>Whether it's chemical or more "natural," leavening relies largely on the production of carbon dioxide.</p><p>When you mix an acid, such as vinegar, buttermilk, yogurt or apple cider, with an alkaline compound like baking soda, you get CO2. That CO2 creates bubbles, which in turn capture steam in the oven and allow a bread to rise.</p><p><span></span>But it's better with yeast. Tastes better, too. It just takes more time. </p>
What is yeast?<p>There are yeasts all around us — on grains, in the air, in biofuels. It even lives inside us, but that's not always a good thing.</p><p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1090575/pdf/1471-2334-5-22.pdf" target="_blank">Candida yeast</a> can cause infections of the skin, feet, mouth, penis or vagina if it builds up too much in the body.</p><p>One of the most common yeasts, however, is <em>Saccharomyces cerevisiae</em>. That's <a href="https://www.dw.com/en/an-early-beer-archaeologists-tap-ground-at-worlds-oldest-brewery/a-45480731" target="_blank">"brewer's"</a> or "baker's" yeast.</p><p>You can get fresh baker's yeast, often in 42-gram (1.48-ounce) cubes, or as dried yeast (quick action or active, which requires rehydration) in a sachet of 7 grams.</p><p>There's little difference: One is compressed and the other is dehydrated and granulated. But they do the same thing, essentially. </p><p>Some commercial yeast producers add molasses and other nutrients. But natural yeast has plenty of useful nutrients in it anyway, including B group vitamins, so who knows whether it's good or necessary to add them. </p>
How does yeast work?<p>When you mix flour, yeast and water, you set off a veritable chain reaction. Enzymes in the wheat convert starch into sugar. And the yeast creates enzymes of its own to convert those sugars into a form it can absorb.</p><p>The yeast "feeds" on the sugars to create carbon dioxide and alcohol. The yeast burps and farts, releasing gases into the mix, and that creates bubbles to trap CO2. </p><p>It's a vital fermentation process that breaks down the gluten in the flour and helps make your bread more digestible.</p><p>The yeast cells split and reproduce, generating lactic and carbonic acid, raising the temperature and ultimately adding flavor to the mix.</p><p>The longer you leave the yeast to do its thing, the better for your bread. Time is more important than the amount of yeast. </p><p>In fact, that's an enduring question — how much yeast? I'll use 20 grams fresh yeast for 500 grams of flour. Others say that's enough yeast for 1 kilo. If you are converting a dry-yeast recipe to fresh yeast, some bakers advise tripling the weight. So, if a sachet of dried yeast is 7 grams, your fresh yeast is 21 grams.</p><p><span></span>But that also depends on the flours you are using, temperatures in the bowl and the room, and a host of other things. You'll just have to experiment and see. No number of books (and I've read a stack on bread) will help as much as trial and error.</p>
Wild yeast: Sourdough<p>So, good bread needs time. If you have a lot of time, why not move it up a notch and grow wild yeast — a sourdough starter — in your own home?</p><p>A sourdough starter is not to be mistaken (as it often is) for the leaven, or "mother," "sponge," or <em>levain</em>. That's more a second stage, a descendant of the starter. You take a scoop from your starter and add it to another flour and water mixture when you prepare the dough for a new loaf. </p><p>The sourdough process utilizes yeasts naturally present in flour and … yet more time. A longer fermentation process allows a richer lactic acid bacteria <em>lactobacilli</em> or LAB to evolve, and that can be healthy for your gut microbiome.</p><p>It's simple enough to start a sourdough starter. All you need is flour, warm water and time.</p><p>Some suggest equal measures of whole-grain flour and water at 28 degrees Celsius (82 degrees Fahrenheit), some say room temperature — just don't let the water exceed 40 C or the yeasts will die. Some suggest two parts flour to three parts water. But it's up to you whether you want a drier or wetter starter. You will know only through experimentation. </p><p>Some say you should filter tap water to remove chemicals like fluoride and avoid using water that's boiled and then cooled. Others say that really doesn't matter.</p><p>The main thing is, keep it clean and give it time. Days, weeks, months and years.</p>
