Smoke before you get in the shower. I always smoke like 3 FAT bowls before I hit the shower and then turn the fan on, take a 20-25 min. shower becuase your so high. The scent of the shampoo and the steam and the fan will take the smoke out within 20 minutes. Be sure to blow the smoke towards the fan. Works for me. I've done this while i was grounded for a week everyday of the week. Parents did not notice a thing. Later man and good luck.
