Im going to be walking around outside near a mall (the more secluded, less obvious part) before I see a movie with my gf. we want to smoke, and figured a joint is the best option. going to hide it in an empty soda can and make it look like a straw. we aren't too worried about being seen, but we both live at home during the summer until we go back to campus. how long after we smoke will we smell like the rolling papers? I know the weed smell dissipates after a few minutes. but I didn't start smoking until freshman year at the dorms, so i never really cared if I smelled like it. will I be cool with a few shots of cologne?
