How long will weed stay in my system?!
It can stay in your fat cells for up to a few weeks if you're a chronic smoker, with a slow metabolism. If you smoke every now and then(maybe a few times a month), and have a fast metabolism it can stay from 2 days to a week. My sister once took a drug test the day after mardi gras and passed lol she's not a pot head though.
It can stay in your hair for months, but most don't test that.
It really depends on the quality and type aswell. It could vary from hour to the WHOLE ******* NIGHT
usally it takes 3-4 hours
in your blood for about 3 months (varies per person) your hair.. forever until you cut it off xD
