I havnt really got a tolerance. I've been smoking large amounts of weed and homemade hash for 4 years now, and 1 joint will get me high, but if i wanted to i could smoke 3 oz in one day, because when i reach a certain point i dont get much higher, sometimes i can over do it and pass out but it depends.

I dont know about tolerance, so i wont comment. Nothing is certain. It's theories, and they dont mean the truth.

Each human is differnt, nothing more to say about it, that somes it ALL up, it could be true in some people, and it could be the opposit for others... doesnt need much more explanation.
