Actually, I have smoked weed. You're the noob, if anything, because weed only causes hunger, fatigue, laughter, and a heavy feeling.
You don't hallucinate. You might change and feel a bit funny. Do you know what hallucinating is?
Again, you don't see unicorns or have false impressions. You are calm, hungry, and you feel a bit tired. There is nothing false about that. A hallucination is when you see something that doesn't exist, hear something that doesn't exist, smell something that doesn't really exist... You get the idea. You're not feeling anything, seeing anything, smelling anything, etc. that doesn't exist. It's a real feeling of calmness and hunger. There's nothing hallucinary about it.
Unless you think a sudden overwhelming feeling of calm is a hallucination? You feel it for real. It's not a fake feeling, because it exists.
Note the "toxic" up there? What did I mention earlier? Ah... I didn't mention poison, did I? No way, I totally didn't /coughs. You're probably talking about American cannabis. That stuff is filled with toxins to cause addiction and other effects cannabis wouldn't normally give.
I'm talking about cannabis that hasn't touched chemicals at all. The typical Canadian cannabis. The stuff that isn't on the news, telling us that weed is bad.
Perhaps you hallucinate with the US chemical stuff, but know that it's not the weed, it's the chemicals / poison ("toxins") on it that is inducing the effect.
As for your experience, staring at the wall and feeling lost is normal, because you feel heavy and skeptical, calm, and "out of it". That's not hallucinating. Swatting at a fly that doesn't exist, seeing your brother's face change... I've never heard of that, except on mush. That doesn't happen with weed. I'm not sure what you took, but maybe you smoked too much than you could handle, and it ****ed you up for a bit. That would be normal. That's like a non-drinker drinking litres of beer in one-shot. He's going to experience a lot of messed up things that if he had slowly gotten into the phase, he wouldn't have.
Uhm. I mentioned a lot of that stuff many, many times. You feel very hungry. You laugh at everything. Sound is more intense and louder. You feel out-of-it and very, very heavy.
I don't know what you've been reading this entire time, but it's surely not my posts.
For the record, under 11 grams is legal in Quebec. Ontario is pretty hardcore about weed possession, though.
I've smoked in front of cops before in Quebec. They don't care. 4/20 is a marijuana fest in central Montreal. Even the cops participate. It's like a mini-Amsterdam.
