i smoke blunts in my bathroom all the time and my dad doesnt notice...i just blow the smoke into the fan and keep the blunt under the fan that sucks air out... then i spray febreeze all over the bathroom and outside the bathroom door...i keep the door to the bathroom closed with the fan on for like 1-2 hours, spraying febreeze every 10 mins and a few sprays of cologne and the smell is completely gone by the time my dad comes home...
