That being said, it is also a "hallucinogen" that alters your perception, so do you really want this to be legal on the streets (so to speak)? Please post an initial claim to where you stand on this issue (legalize it or do not) and why you feel that way.
a) Legalize it - It has potential medical benefits and can be regulated for safety.
b) Do not legalize it - It poses health risks and societal dangers.
c) Need more research - Further studies are needed to determine the full impact.
d) Decriminalize it - Treat it as a public health issue rather than a criminal one.
