Smokin at 13 and growin regs seeds from the first few sacks i got shortly after that. Didnt produce fruits so i wouldnt say that was the start but it was the beginning of the end. haha. So id say around 15-16 i got it down to a pretty good science.
smoked once in a great while from ages 15-24 then nothing then in 2010 I began smoking or using medibles daily wont stop either.. infact have some pumpkin spice Bubba Kush cookies in the oven right now..
