Both and it depends on who catches you for the charges. Marijuana is not legal in any states. Medical marijuana programs exist which allow patients on the program to legally possess up to certain amounts and have so many growing plants. It is still illegal for them to sell marijuana, they can usually exchange it between other patients depending on the state.
If you are caught with marijuana out of your home state, you may face criminal charges according to the laws of the state where you were caught. Penalties can range from fines to imprisonment, depending on the amount of marijuana and the laws of the state. It's important to be aware of the marijuana laws in any state you visit to avoid legal consequences.
Millions. On top of all the people using it recreationally and (unfortunately) illegally, several states have medical marijuana programs. In California, for example, you can apply for a marijuana card with your doctor's recommendation and you can actually go to one of many stores across the state that legally sell marijuana to patients. They even have marijuana vending machines at some.
While hotly debated, marijuana does reduce the neurological pain that MS patients feel better than the toxic, highly addictive (yet somehow still legal) manufactured drugs like OxyContin. It also reduces nausea felt by chemotherapy patients, and it also reduces intraocular pressure that cataract patients feel.

Sadly, medical marijuana users can still be prosecuted by the Federal government for illegal drug use.
You may only get medical marijuana if you are in a state/country in which medical marijuana is legalized. Some states have only legalized the CBD-extract to treat patients, for example New York. The qualifications vary according to state, most however, agree that PTSD is a qualification, as well as epilepsy, seizures, and cancer patients. Certain states like California hands out medical marijuana cards for just about anything, from migraines to cancer - practically anything. Overall, it really just depends on where you live, and if it's even legal in the first place.
