all of my reading on the web about whether testing positive from taking CBD says it is very unlikely. very slim unless you're guzzling the stuff. well i have done about 10 dropper fulls over 3 nights. and thought well, just to be on the safe side, i will buy some tests at the local dollar store and see. the cbd i have says it is 200 mg high potency. i dont know what that means exactly. but i tested positive according to my tester from the dollar store. i am glad to know this, and not really worried because i know it will leave my body in 2-3 days. i havent toked up for years. i am surprised that every thing i have read says it is unlikely to test positive.. i would hate for some guy on parole to do some of this thinking he would test negative, and get a positive out of it. i think in that case. while not my concern. so has anyone else tested their self after doing cbd for a while ?
