dude im 18 i smoke since 14 and i deal, for the past years ive been smoking a lot everyday and the tolerance gets high, becuz in quebec ppl only grow hydroponic m39 becuz it growz really fast and when when ur used to a strain it wont get u high anymore, m39 its mostly an indica plant, thats anothe problem, i HATE indica, whats the point of being down and then having another down, sativa is fucktop becuz its an energetic high with laughs so in conclusion, go to www.drchronic.com order some seeds some are less expensive, buy urself lights and material, for the 1st grow invest like 500-700$ max and grow like 10 plants and ull get experience after, one of my friends has a basement with 25 plants and he just grows 1 time a year and has enough for the whole year for him and a couple of his friends, so if u really want to get high and i suppose if u smoke since 15+ years u should be at least 30 years old so u should have ur place by now so just grow it
