How long before a chronic smoker of marijuana will test positive in a urine test?
I think you may have meant to ask how long before they no longer test positive. Because a chronic smoker will test positive within a short period of time. A chronic smoker should give it a week and a half to two weeks of abstaining before a urine test shows negative. Up those vitamins, and ginseng and drink ALOT of water I mean 10 – 12 glasses a day and don’t take caplet vitamins take liquid or gel caps. The hard vitamins usually just pass through your system they are a complete waste most of the time.
