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 taken for medical purposes.
The marijuana plant contains more than 100 different chemicals called cannabinoids. Each one has a different effect on the body. Delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are the main chemicals used in medicine. Cannabinoids — the active chemicals in medical marijuana — are similar to chemicals the body makes that are involved in appetite, memory, movement, and pain.
To get medical marijuana, you need a written recommendation from a licensed doctor in states where that is legal. (Not every doctor is willing to recommend medical marijuana for their patients.) You must have a condition that qualifies for medical marijuana use. Each state has its own list of qualifying conditions. Your state may also require you to get a medical marijuana ID card. Once you have that card, you can buy medical marijuana at a store called a dispensary.
