I myself have never had a hallucination on weed, minus one time-where I had a sort of hallucination
I was in Amsterdam and I spent part of the day trippin on shrooms (thai), which I found to be weak, but still something. Later in the day my friend and I pulled into a bar and pulled out our northern lights. He hates tobacco and until then I had always spliffed our joints. He insists on doing pure weed (I bet you guys can see what is comming) because he wants to taste the sweet smoke and not deal with tobacco. So I reluctantly oblige.
Large joint of pure northern lights. We smoke it between us, and realizing what its going to do to me I tap out before its finished. We walked around the streets and eventually went into a mc Donalds to grab somethin to eat, or sit down because I was freaking out, I cant remember. Inside the mcdonalds my vision was so fucked up, the world looked sorta distorted and like there was a strobe light on, like flashing light.
Needless to say it was fucked up. I had been too high TONS of times, but never that high, not even on DXM plus weed.
