That's what I always think but even if I don't think I smell like it, if I have to go some where important I change clothes. Trust me even if you don't smell it unless you were smoking from a bowl your clothes DOES smell. If you smoked a joint or blunt you can bet your ass smells like smoke. The weed doesn't even have to be that potent, fact is there is a lot of smoke. But very potent bud is even worse for smell lol!
