Medical cannabis
Medical cannabis, also known as medical marijuana, refers to the use of the Cannabis plant, or its various extracts, for the treatment of various health conditions and symptoms. Its efficacy and legality vary greatly around the globe.
Pharmacology[edit | edit source]
The primary psychoactive component of cannabis is tetrahydrocannabinol (THC), one of the many compounds found in the plant. Other significant compounds include cannabidiol (CBD), which has therapeutic effects and does not produce the psychoactive effects that THC does.
Medical Uses[edit | edit source]
Medical cannabis is used in a variety of medical conditions, including chronic pain, nausea and vomiting due to chemotherapy, and severe forms of epilepsy. However, not all of its uses are supported by robust scientific evidence, and more research is needed to determine the safety and effectiveness of medical cannabis in these conditions.
Administration[edit | edit source]
Medical cannabis can be administered through various methods, including vaporizing or smoking dried buds, consuming extracts, or eating cannabis-infused foods. The method of administration can affect the onset, intensity, and duration of psychoactive effects; effects on organ systems; and the addictive potential and negative consequences associated with use.
Risks and Side-Effects[edit | edit source]
The use of cannabis can have numerous side effects, including dizziness, impaired memory and cognition, and the potential for addiction. Long-term use can lead to chronic respiratory issues. It is also contraindicated in individuals with a history of psychotic disorders due to the potential exacerbation of symptoms.
Legal Status[edit | edit source]
The legal status of medical cannabis varies widely around the world and within countries, with some jurisdictions allowing its use and others criminalizing it. In some regions, it is legal to use for medical purposes but not for recreational use.
Research[edit | edit source]
Research into the medical uses and safety of cannabis is ongoing. It has been challenging to conduct due to legal restrictions and variability in the concentration and quality of products available.
