Now that it's winter, and it's to bitterly cold to go outside ( i live in PA ) during the night, i smoke up in my room, out the window. I would like to have advice or just throwing your 2 cents in about my 'system'. So on a friday or saturday night, i smoke my small bowl out the window. My mom is downstairs drinking and smoking cigarettes, so i'm not to worried about her barging in, especially when I tell her i am going to bed. The window dosnt have a screen, so i lean out the window and just smoke, using a doob tube if i get too paranoid. I light a candle, have the lights dimmed down so it dosnt look like alot of light is coming from my room, as if i was doing something. I stand between the back of my Amp and my wall. I put plastic bags at the beggining of the hallway so if anyone steps on them I can hear them coming. I also have a ceiling fan but i just think it circulates the smell even more... Any advice?
