Shirts are a big one! If you smoke joints especially (or blunts, or anything that is constantly burning) than your shirt will begin to smell. Last night before a party I smoked half a joint right before I went in, put it out, put it in an extra PH testing tube I have (glass tube with airtight top), stuck it in my car, and my shirt smelled a bit. Then I went back halfway through and smoked the rest. Long story short, I made it a shirtless dance-party because it smelled so bad. Luckily I have abs of steel!

So point of the story, smoke a J if you want to have a shirtless party and bring an extra shirt if you want to wear one, or bring a light perfume.
