 Subj : BLOOD drug test?

   Blood tests are much more benign than urine tests.  In general, THC
only shows up in blood for a few hours after use, though chronic daily
users may register positive for a couple of days. (In fact, very low
levels of THC can theoretically be found for days in casual users, but
standard lab tests are not sensitive enough to detect this).  It would
be far preferable if persons subject to random drug testing had the option
of choosing a blood test, since they would be far less likely to register
positive unless they were truly under the influence.  For a writeup on
drug testing, contact Cal NORML:  2215R Market St #278, S.F. CA 94114
or call the NORML drug testing hotline: 900 97-NORML
