For "medical use" I guess we could lump all the ADHD/ADD drugs as they are basically legal speed, or "therapeutic amphetamines"
Marijuana is no psychedelic. The writer doesn't know what he's talking about. There are tens of millions of Americans who have taken psychedelics, and a hundred million who have used marijuana. Why aren't they employed to write about the subject.
Honestly? That author is retarded and should at least learn about the subject before he opens his ass.
