arent step dads supposed to be super chill with you?
If time has taught me anything its this. If you get caught smoking/drinking then tell them youll stop. But don't. If you get caught again explain how it was a one time thing. Wash Rinse repeat. Eventually they'll get desencitized.
you dont have to change anything, just continue what your doing and dont be an idiot about things.
