There are several methods of analysis available for detection of delta-9-tetrahydrocannabinol (delta-9-THC), a biologically active component of marihuana derived from Cannabis sativa L. These range from simple colorimetric tests (Beam 1911) to the Duquenois-Levine reaction which replaced the Beam test (Hahas, 1975). Analytical laboratories having available to them gas chromatography instrumentation utilize the procedures of Lerner (1986), Fetterman et al. (1971), Turner and Hadley (1973), or the DEA (1976) method when small quantities of material are evaluated.
