Unfortunatly I dont think 2 or 3 days will do it Unless you use another method (some sort of detox kit, Synthetic Urine etc..)

Extra Water should help, as it will dilute the overall contents of the urine, i.e. theres the same amount of thc metabolites but theres more water, so its "concentration" of THC is lower because of this, But i hear if u piss clear u fail, So you need Vit B-complexs to Replenish the yellow colour.

With whatever you decide to do.. Good luck :thumbsup:
