Last year in a four story dorm these guys smoked and you could smell it in front of all 100+ rooms in each hallway. I always smoked in my van (E150 with window shades hell yea). One time I even started smokin in the parking lot and in the car next to me was another dude smoking. If you see a cop coming in the parking lot immediately put ur shit down and walk out of the car and walk away. Never got caught.
One hitter and a dugout is essential for dorm life btw. Finally got my own place and can use my bong and bowl. Ah the joys of living in a house in the woods with two other stoners.
Sorry, third post in a row. I hate incense. My buddy went through an "incense phase" where he wanted to light incense every time we smoke. My dad never smelled weed in our garage when we just aired it out, but he asked about that fruity smell for a whole week...
