בדיקות שתן לגילוי עישון גראס

שאלה מאוד מעניינת בדקתי וראיתי את העניין ואכן יש משהו בדבריך והנה אחד הקישורים לעיונךPassive smoking. Don't hang around people who are smoking marijuana, hashish, or crack cocaine. If you inhale some, it could result in a positive test. (Remember the Olympic snowboarder who almost lost his gold medal?) Note that marijuana and hash, unlike most recreational drugs, require longer than a few days to pass out of the body. In fact they can often be detected in a drug test for up to a month after use because THC (the active ingredient) clings to the fat cells and metabolises very slowly. Also, be aware that if you test positive for any drugs at any time during a trial, you will usually be withdrawn and receive no payment. Also, try not to inhale an excessive amount of second-hand tobacco smoke, as this could result in a positive test for nicotine.
