If you just take one bong rip, around how long would that stay in your system?

I always hear that it takes 30 days to get pot completely out of your system, but for someone with low body fat content and just one small bong rip, i'd still fail a drug test by the 20th?

Also the only thing i drink is water, no soda, no juices or anything just water. It's been that way for a few years, so i feel like that would help speed up the process too.

It depends on how they test hair follicles go back decades.

It's just a piss test for probation.

like if you fail you will go to jail?

Hair samples goes back 7 years. piss it mainly depends body fat and if you work out or not it could take anywhere from a few days to a month.
