1. Oust and Febreeze (don't forget to do your clothes)
2. Candles that smell earthy like apple cider, basil, or pine
3. I do think it is smart to practice your facial expressions in the mirror
4. I exhale into my pillow or into a sweatshirt, the doob tube is the obvious choice but if you don't want one around then you can try this instead
5. Don't freak out! Just act normal.
6. Don't smoke so much that you just act stoned... try to do the weed equivalent of "a beer or two" and no one will know. You get in trouble when you get really freakin' high and stumble around like a moron.
