A gram of weed a day is a pretty low amount dude, like clearly it is smoking everyday and enough to get stoned a couple of times but it is hardly 24/7 blazing being fucking perpetually stoned like a LOT of smokers are.
I would never go so far as to say I felt weed could not get me high but if you compared the high I was getting you to what most people do you could really almost say that I wasn't. It just becomes a really, really mild effect that is hard to notice and thats what I meant in my previous post when I said at a point cannabis tolerance doesn't increase the volume you smoke it just decreases the intensity of its effects.
I ain't trying to be a dick or come across like I am dicksizing my weed smoking habit with yours, because I am not. But in the scheme of things you must realise that a gram of weed in the spectrum of things is not a very large amount for a heavy smoker to go through in a day, not at all...
