100 euro here of weed would last only a couple of hours for my friends . They take grams worth in bongs . I'm not working though , i'm a student which means i'm pretty much broke all year around . If good weed comes in i'll go out of my way to get it though .
I'm the same with my friends. We usually get a 1/4 for €90-€100 between 3 or 4 people and we'd have the bag finished in a few hours. It's just sore on my wallet between buying bags and going out to parties or bars. Although, I always find I can gather up the money I need for weed/alcohol relatively easy. Before I started taking anything, I would have the same amount of money I still have now, so in a sense, it's not too bad actually.
