What I think Illn is trying to say the more you smoke, the longer it will take you to get clean. This includes taking into account the quality of the weed, how often you smoke, and how much each time.

Dro doesn't always mean stronger.

Most people can pass a THC test after a one time high in 5-7 days if the body is completely clean. After that, your guess is as good as mine. Drinking copious amounts of water won't flush your body like pressure washing a driveway. Stay hydrated but don't overdue it.
