Question : How long will THC show up on a breathalyzer test?
I go to a really conservative university, and have to take a breathalyzer test in a week or two. I’m wondering how long weed will appear on a breathalyzer. If longer than one or two weeks what can I do so it won’t show up on a breathalyzer.

Thanks for answering the question!

thc doesn’t show up on breathalyzer test. that’s for alcohol. they test for thc by urinalysis. that will show thc for a month or more at the very least.

if you have a urinalysis you need to flush and detox your system. you can buy various types of formulas for this but they are not dependable, so here’s what you do: google niacin flush (many of those formulas use this process). you can buy niacin in health food or supplement stores etc. for a fraction of what they charge for those bottled formulas. niacin flush is a detox process. it may turn your face red for awhile, so do this when you have some time. (totally safe). do this daily for a week and drink lots of water for a week or two. or three if you have the time.
