Man, if I could get my hands on a gram of hash per day I might never smoke bud again. Been years since I've even seen hash.
edit: other than what I've pressed myself, that is.
About half an ounce fills my friend's tin- assuming this is your 'average' sized tobacco tin. I've yet to check how much my old golden virginia tin holds...
I think once your familliar with weed you can just smoke and smoke and smoke... With no tolerance and nothing to do I could go through and 1/8th alone in a day.
But seriously, once you start wake&bake with nothing to do and a stonewall of a tolerance, the only limitation to what you consume is supply and lungs lol
