Hello all. This is another question about drug tests

. I just wanted some input. I recently had to stop smoking bud for probation, that will last about 6 months.

Lets say I have been a regular 'user' the past 8 months (every day, if not every other day, not too much, probably just .5 of dank on avg) from January untill about 6 days ago. So I stopped cold turkey. How much thc do you think is in my system, will it even be possible to get it out in 30 days or sooner. I have been taking 500 mg niacin daily, drinking shit ton of water, and excercising. Also bought a 'drink' as a backup called (Omni Purified Extra Strength), my test could come up randomly anytime, but most likely towards mid-late september. Realistically do I have any chance at all of passing, btw Im 6'5, 250, so yeah. Im probably fucked aren't I. I had always assumed it gets out in 30 days max, but with such frequent use over long periods of time, does it take longer after you stop completely?
