CAUTION & DISCLAIMER #
Erowid's drug testing information is a summary of data gathered from site visitors, journal articles, websites, and other resources. Detection periods depend on amount and frequency of use, metabolic rate, body mass, age, overall health, drug tolerance, and urine pH of each individual. Many substances that are not tested for in basic or extended urinalysis tests CAN be tested for by a laboratory willing to go to the trouble, although that is uncommon.
