see above. Once you shave your head, slate is wiped clean. (provided you havent done anything in a while). When your hair regrows it does not keep a "memory" of the drugs used. It is quite a bit more accurate than the whiz quiz because it can detect very minute amounts from people who do a drug infrequently.
