It depends on what kind of mood I'm in. If it's one of those nights where I want to smoke myself retarded, there is no limit. I like to just ride the trip that I used to freek out with when I was a novice. I don't do that very often though.

I usually smoke a half a bowl (I think my bowl is about .5 grams?) and I'm good for a few hours cause I like the nice calm high. This is what I do when I'm going to do an activity, have a headache, stomache ache or just want to have that relaxing feeling it gives me.
