first of all, howd you know about the fridge in the garage thread lol.

me being 16 and having been in a similar situation myself, i think im somewhat qualified to help you out.

i was caught when i was 14 years old (well not really caught, narked) and it crushed my mom. she felt like a failure for raising a stoner (i woudlnt even consider myself a "stoner"). i told her i would stop but of course i didnt. why would you stop something that you enjoy just as much as reading or exercising? sure its illegal but almost everyone on this forum knows the reasons are bullshit and for someone to make a natural plant that grows in this environment illegal is also bullshit.

we dont know you, and dont know your son, but if hes like most kids, i dont think hes going to stop, especially if hes educated on the subject. theres two scenario's that could happen:

1. hes really just experimenting, blazed, liked it and is done with it now.
2. he likes it and isnt going to stop.

whichever option, its important that you explain to him and he understands that you use marijuana for medicinal purposes and even though you cant really tell him to stop, you let him know that being the adult you think 15 is much too young to be smoking. (which i believe it is).

sorry for the rambling, i hoped that helped somehow. but bottom line, talk to him. make sure you guys are on the same page. dont threaten him wih grounding or w/e because that will cause him to rebel.

this is a tough situation for everyone but communication is best at this point, let us know what happened by the way.
