What can my parents really do if I get caught smoking Kush?

You got lucky it sucks hard when you get caught - trust me I've gotten caught many times :/

Make a sploof then just blow your smoke into that if you're in a ventilated room. Or get a vape.

 

Honestly if this happened to me, my dad would probably light up a bowl with me. Butttt if my mom caught me i would be in a hole filled with barbed wire snorting dirt because it'd be berried alive.

 

LeetNeo! It's been too long man!

But in regards to your problem, legally, if it is their house they can do whatever they want. Respect them.

 

I wouldn't do pot near your house again. Since your parents are already suspicious, it's really likely that they would keep an eye on you.

I would stop for a while, and occasionally do it away from home.
