I have had a full blown hallucination of chronic. My body was apart of the music and I could see it and my body spawned into weird things in time with the music. Its hard to explain but yes, some people can hallucinate. It might be a certain thing. I don't hallucinate if there isn't music. And um so passionate about music it allowed me to *become* music.
Because after I had smoked once I remember telling my girlfriend to shut the window after it aired out because I didn't want bugs coming inside, and she said no. And then she fell asleep and I was reading a book and I started seeing the sheets move and it looked like little spiders crawling over the sheets and I tried swiping them away. It was crazy.
Marijuana does contain a mind altering chemical, I believe and it probably depends on the purity or strength of the marijuana that is smoked as to whether or not you will hallucinate. As with most drugs, different people have different reactions so I don't see it as unlikely that some people might have visual or auditory hallucinations.
Marijuana alters the brain's activity and makes one see things that aren't really there. The drug also has the ability to give people a false perception of reality, cause some individuals to think they are stronger and smarter than they are when they are sober. These are classic signs of hallucination.
Marijuana is a drug that messes with your state of mind, of course it can make you hallucinate and see things that do not really exist. It alters your reality to allow you to escape from the world your in, it almost takes you completely to another place all together. It is completely possible.
Marijuana is not known for being a hallucinogen. Marijuana is a depressant which calms the bodies functions. It does not hype them up like other types of drugs like acid or ecstasy. Marijuana has been known to be relatively harmless in the long run and not known to cause crazy side effects.
Never happened once in the many years I used it back in the day. It can make you paranoid and can certainly throw your world off to a degree, but if you're having hallucinations there's probably something in what you're smoking that you didn't sign up for. I've never seen anybody experience this.
