My friend suggested tincture of California Poppy for my insomnia. I've been taking it nightly now for maybe 3 weeks. It makes me sleepier but is not a sure answer. Now my coworkers are telling me that it can make me test positive on a drug test. Everything I read says stay off it for 48 hrs prior to drug test but, when my job tests me (which is fairly often) it's immediate. Boss comes and says time for drug test, he drives me over to the testing site. I cannot even take a purse. So, should I stop taking it? If so, how long will it stay in my system?
