Marijuana's therapeutic uses are well documented in the modern scientific literature. Marijuana has been shown to be effective in reducing nausea induced by cancer chemotherapy, stimulating appetites in AIDS patients and reducing intraocular pressure in people with glaucoma. There is appreciable evidence that marijuana reduces muscle spasticity in patients with neurological disorders.

Pure THC may also produce more unpleasant psychoactive side effects than smoked marijuana.
Many people use marijuana as a medicine today, despite it being illegal.
In doing so, they risk arrest and imprisonment.
