Hmm

Wondering if I should tell my dad I smoke weed lol when I didn't have a dealer I always took some from his stash, So as his him being more of a stoner than me not really sure he would care but... what do you guys think, (I'm 15 btw)

He will eventually find out, so it's better for you to tell him yourself. Just say "Hey dad, I decided to try weed and I decided I liked and I've been having it for a while"
