your bathrooms gunna reak, if gotten caught 2x that way and i only toked a bowl and then took an hour bath and when i got out my mom still noticed. if u dont wanna get caught my advice is to get a small fan, turn it backwards and place it out r window, breathe into the back of the fan and everything gets blown outside andno smoke gets blown back in via wind from outside or take a tiolet paper roll fill it with fabric softener sheets and toke inside ur closet, just breathe out through the toilet paper roll and ditch it when ur done.
