This test will test for the presence of THC (marijuana) Cocaine Amphetamines Methamphetamine Opiates and Benzodiazepine (tranquilizers or anti-anxiety agents such as Xanax) in urine. Just dip the test into urine and get your results in 5 minutes. You will need only enough urine to absorb into the test strips. A positive result will show 1 line and a negative result will show 2 lines. Just having the drug test readily available can sometimes be a deterrent.
