At least what age should one be to consume cannabis?

[Kryzco]

whatever time one is mature enough to handle the herb... could be 13 years old, could be 31 years old.

It's all about keeping herb in moderation, and not letting it take over your life.

i agree 1000%

I also don't like seeing these 10-11 year olds tokin up because they are so young and most likely doing it for all the wrong reason, and most of the time they honestly can't handle themselves while high
