Medical marijuana uses the marijuana plant or chemicals in it to treat diseases or conditions. It's basically the same product as recreational marijuana, but it's. It could be from headaches, a disease like cancer, or a long-term condition, like Doctors also may prescribe medical marijuana to treat. The term medical marijuana refers to using the whole, unprocessed marijuana plant or its basic extracts to treat symptoms of illness and other conditions.

Marijuana and Cancer Marijuana is the name given to the dried buds and leaves of varieties of the Cannabis sativa plant, which can grow wild in warm and tropical climates throughout the world and be cultivated commercially. Marijuana Different compounds in marijuana have different actions in the human body.
The effects of marijuana also vary depending on how marijuana compounds enter the body: When taken by mouth , such as in baked goods, the THC is absorbed poorly and can take hours to be absorbed. When marijuana is smoked or vaporized inhaled , THC enters the bloodstream and goes to the brain quickly. The second psychoactive compound is produced in small amounts, and so has less effect. The effects of inhaled marijuana fade faster than marijuana taken by mouth. Some of these cannabinoids are extremely powerful and have led to serious health effects when misused.
The body also produces its own cannabinoid chemicals. They play a role in regulating pleasure, memory, thinking, concentration, body movement, awareness of time, appetite, pain, and the senses taste, touch, smell, hearing, and sight. State-approved medicinal use of marijuana is a fairly new practice. THC can increase appetite and reduce nausea. THC may also decrease pain, inflammation swelling and redness , and muscle control problems.
It may be useful in reducing pain and inflammation, controlling epileptic seizures, and possibly even treating mental illness and addictions. For instance, recent animal studies have shown that marijuana extracts may help kill certain cancer cells and reduce the size of others. Evidence from one cell culture study with rodents suggests that purified extracts from whole-plant marijuana can slow the growth of cancer cells from one of the most serious types of brain tumors.
Research in mice showed that treatment with purified extracts of THC and CBD, when used with radiation, increased the cancer-killing effects of the radiation. Some women report using marijuana to treat severe nausea they have during pregnancy.
But there's no research that shows that this practice is safe, and doctors generally don't recommend it. Pregnant women shouldn't use medical marijuana without first checking with their health care provider.
Animal studies have shown that moderate amounts of THC given to pregnant or nursing women could have long-lasting effects on the child, including abnormal patterns of social interactions 11 and learning issues.
They treat nausea caused by chemotherapy and increase appetite in patients with extreme weight loss caused by AIDS. Continued research might lead to more medications. National Institute on Drug Abuse website.
All the documents are available online, and are fully referenced , but I will summarize each document here:. Evidence for inhaled marijuana for pain is too sparse and poor to provide good evidence-based guidance. Synthetic MC-derived products may modestly improve neuropathic pain for one in users but perhaps not for other pain types.
Additionally, longer and larger studies better evidence show no effect. Adverse events are plentiful. The full document is available here. Compared to placebo, medical cannabinoids cause multiple different adverse events in patients, from visual disturbance or hypotension 1 in to hallucination or paranoia 1 in Stopping due to adverse effects occurs in 1 in every patients.
Regardless of the type of medical cannabinoid used, adverse events are common and likely underestimated. Given the extensive harms, potential benefits must be impressive to warrant a trial of therapy. For most conditions example anxiety , cannabinoid evidence is sparse at best , low quality and non-convincing. Studying marijuana under rigorous circumstances has been difficult until fairly recently.
The other issue is the challenge of a proper placebo control, particularly for non-oral forms of use. Given the psychoactive effects and the widely heralded effects on conditions that can only be assessed subjectively, like nausea, fatigue or appetite, a proper placebo is essential to separate out actual from placebo effects. While some commercial products have been developed and marketed with standardized ingredients and quality control e. However, these purified and standardized products have allowed for proper placebo controls and more rigorous assessments of effectiveness.
Hopefully, clinical trials will become more common and more marijuana-based drugs can be more rigorously evaluated. The use of psychoactive drugs like marijuana is a health issue, particularly when used for medical purposes. Regrettably, there is a lack of high-quality data that shows marijuana for most medical purposes is both safe and effective. What little evidence exists is of poor quality and may not even be representative of the purposes for which medical marijuana is sought.
There are significant gaps in information necessary to treat marijuana like other forms of medicine: Dosage standardization and overall quality control may not be in place. Overall effectiveness, contraindications, drug interactions, adverse events and long-terms risks when marijuana is used as medicine are not well understood. The best evidence suggests that marijuana may be a reasonable treatment option only when safer, more effective, and better tolerated treatment options have been tried first.
Marijuana as Medicine
So how, exactly, does medical marijuana work to treat these conditions? Why, if this medicine is so effective for some people, does it remain controversial and. Conditions include insomnia, arthritis, cancer, MS, etc. Research suggests cannabis can help patients treat the pain and muscle general health perception, ability to work and depression all saw notable improvement. While medical cannabis can be used to treat a variety of health conditions and While the exact mechanisms of how this works are not yet fully.
