2 joints daily is that? 6 joints on a saturday, dosent sound too bad at all mate.. ive been going through about 5-6 joints on my own every day no problem the last month, weekends fuck knows how much i smoke then cos its generally with people, but even more thats for sure..
anyway since youre 15 i think youre taking gcses this year? i did last year, and quit smoking in any routines completely, maybe the odd weekend, but i just totally stopped it, and tryed to focus and catch up at school, whether it would of mattered if i was smoking anyway i dont know, but i got the results i needed and now smoke as much as i want

anyway what ive said dosent answer your thread at all, mainly because its up to you.. youre far from being a junkie so dont worry about that lol, if you can keep up with school work then fine, you decide how much you want to smoke, we all know the health effects, especially with tobacco (i also smoke with it but wouldnt say im addicted, even though i have for well over a year + 1/2.) just focus on whatever youre meant to be doing (revising etc) and save those spliffs for the evening

oh yeh just remembered youre smoking 'hash' well ill assume thats soapbar, which to be honest really is bad to be smoking, thats the shit thatll fuck up your head in bad ways, i know its so easy to say, but maybe think about stopping smoking completely for a bit? ive done that, get yourself under more control, and seriously look for a weed dealer!
