I smoke everyday after work on week-days and all day long on weekends.
I don't spend any money in bud, I grow my own!
I spend about 20€ in electricity every month and maybe 15€ or 20€ on other stuff when I'm growing but I don't grow all year. I'm making now my second harvest this year and probably my last as my stock will be enough to cover at least the next 6 months. I sometimes have to spend some more on improving and maintenance of the grow.
Since I grow my own I just smoke the kind bud leaving leaf material for hash making or for cooking. Bud is way more potent and tastes much better than leaf. Although the leaf material I keep for hash making is pretty potent the buds are much better to smoke.
