I donā??t think your gonna like what I have to say but here goes

I donā??t see any other option for you right now other than quitting. Your a minor living in your parentā??s home. If there gonna drug test you which believe me they will (there not gonna forget about this) it will more than likely be a urine test but then again who knows. They might get some over the counter drug test or they might take you to your regular Dr. Either way I donā??t know of anything you can take that will make you piss clean. If there were something believe me every stoner would know about it by now. The key here is to stay clean at least until you know how the drug test is gonna take place (how much privacy your gonna have and so forth.) First you have to know what the system is then you can think of ways to beat the system.

Things will be ok.
