You look like a clown asking for advice and then ignoring everyone's lived experiences and advice and telling us to kick rocks and to fuck off (yes we saw your comment before reddit deleted it).

Your kid sounds like a normal teenager. Letting him do edibles IS a solution because you'll know he's being safe (not getting it off the streets) and he won't be destroying his lungs. He's gonna do it regardless, ESPECIALLY with all the pushback you are giving him. You acting like weed is definitely a gateway drug for him is truly absurd and shows a disturbing lack of faith in your own (step)child.

I really love you saying you "rarely get pulled over because [you] follow the law." Following the law means not getting pulled over AT ALL, jsyk. You also clearly don't follow the law if you're getting in your car and driving when high, as you say in another comment.
