Answer:
#1 - Hallucinogens tend to be illegal because they can cause major damage to you and cause you to go insane. Most hallucinogens make you hallucinate and see things that aren't there which eventually makes you panic and if you aren't in the right state of mind that can be really bad for you. Unlike most hallucinogens, marijuana doesn't make you hallucinate nor does it actually harm or affect you in a negative way and cause you to go insane which s why marijuana is legal and other hallucinogens are not.
#3 - Depressants contain things to make one consuming them more hyper/energetic and seem happier but it doesn't do anything mentally. Depressants have some of the same things as meth which is why they have the affects on the consumer like they do. Stimulants have the same as marijuana. A lot of anxiety medicine has CBD which is the part of the plant that doesn't get you high and then a lot of the medicine they give to kids with ADHD/ADD has parts of the plant as well which is why when they take these medications they tend to look like zombies.
#4 - Marijuana is used a lot for anxiety and pain and it works really well however the only thing making it a drug is being able to get high off it. You get high fro the THC in the plant not the CBD so doctors use the CBD but the THC is what helps with joint ans and stuff like that. You don't hallucinate with marijuana and it doesn't impair any major abilities like vision its only negatve affect is making you lazy
