I know once we all get older we think youngin's shouldnt be doin it but the young ones think that they are old enough and it's not right that age is restriction. We've all gone through it I believe, alot of people in this thread says that 16, 17 is a good age to start if anything (I'm of age lol), but the Bible says after your 12 your responsible for your own actions so I believe if a 13 yr old wants to smoke then let him do it. What happens to him is his issues, if some one doesnt want to listen then let them go ahead. Marijuana is'nt all that bad, maybe to smoke but not to consume, it's a herbal for all I'm concerned.
