Get OUST air freshener, its practically scentless. Also, dont smoke a Joint, use a small pipe or a one hitter. One hitter would be best. The key here is to controll all the smoke and where it goes. It should either be in your lungs, or out the window. Also, dont let anything continuously burn, once youve taken your hit, cover the weed with your lighter and put it out till your ready to take another hit, then relight.
