What pill clean weed out of system?

Quit smoking at least 48 hours before test. then If you take 4 aspirin and drink a lot of water prior to your drug screen you will pass with a false negative. However it only works while the aspirin are in your system.

take 2 aspirin 2 hours before test, and drink a half of gallon of water.

take 2 more aspirin 30 mins before test and drink another half gallon of water.

Passed two test this way.
