i would never let anyone grow inside of my house...thats serious jail time for ME if THEY get caught. but i would let them smoke bud starting at 15

but i kno if they started tokin at 13 or sumthing that no matter wat i would do they would still toke so i wouldnt do much except talk to them and let them kno that once there 15 they could toke around me (when i got caught toked up on the very same day even tho my parents were pissed as hell and disapointed
