Would you support the legalization of psychedelic drugs?

Hell yes. I think all drugs should be legalized. The war on drugs is just stupid. Although I'm not sure what you mean by psychedelic drugs. Do you mean only the ones you've stated? If you mean drugs that have been created by some chemist in a lab (except LSD, because it's virtually natural, but requires some chemistry knowledge) then NO. I personally like to stick to ALL NATURAL or virtually natural drugs, or as I like to call them entheogens. These substances have opened many doors into my perception of myself and my environment.
