How can i clear my system for marijuana quickly?

Combine milk w/clorox. It'll clear it in about a few hours but trust me it burns your throat.

Also, if you drink bleach it will clean marijuana out of your system in a few hours, drink about half a cap of it. However you can get brutally ill from this. To prevent illness drink lots of water(to flush out the bleach), eat lots of food(the bleach destroys all nutrients from food that remain in your stomach), and refrain from talking(talking can irritate your throat and (a)make it hurt for a bit and(b)make you vomit).
