My weed "hobby" would probably cover everyones hobby here, cuz its expensive. I started when I was around 16, I'm 23 now, I started smoking everyday when I was about 19. Sometimes smoke more than a gram a day if I'm chilling hard lol.
So lets see, everyones local price is different, but lets just say I had a discount, and got a gram for 10 dollars.
10 times 365 is 3650, 3650 times 4 is 14600 I believe. I'll go ahead and minus a couple thousand to compensate for possible over estimation. leaving it at 12500 dollars for the past 4 years. holy shit I could buy.... half of an expensive car!
Another expensive hobby I had, was the tabletop game Warhammer 40000. I must have spent hundreds on those little figurines, and paints, and accessories, and glues, and other shit lol.
