No it doesn't. You seriously don't know what the Hell you're talking about. I have a friend who smokes as much as Bob Marley a day of the best stuff available on the market (hellah expensive); it has never, ever, ever made anyone I know hallucinate.
I seriously doubt you have any personal experience with weed if you're seriously saying it makes people hallucinate. Nothing flies. There are no dancing faeries or unicorns. Colours stay the same. You just feel heavy and spaced-out. Nothing more.
Also, I've smoked it, eaten "special brownies", and been hot-boxed several times. I never hallucinated once. Ever. And neither has Robert, who smokes just as much as Marley did being the drug dealer he is, David, Yuss, Antonin, Yusuf, Joseph, Ashille, those other guys Robert would bring over, and those many, many customers who stopped by to pick up their dose for the day from Robert when he visited us those many times a week.
Again, the stuff from the US is crazy and chemically treated. I'm talking about pure cannabis taken from the plant and smoked on-the-spot. No chemicals. Nothing laced on it. It does not make you hallucinate. It doesn't even distort colours.
Only chemically-treated / poisoned / laced weed would make you hallucinate. Not weed itself.
For the record, poisons do make you hallucinate, so if you were inhaling the smoke from a poisonous chemical on weed, then yes, you would hallucinate. It's not the cannabis, though. It's whatever the Hell's on it.
[Edit] I forgot our neighbour, Francis. He'd smoke over at our place since his girlfriend would beat him if she knew he was smoking :|
Oh, and that guy who oes Rob 400$CAN. He never hallucinated either, and like Rob, he's a freakin' addict.
