Initially, it brings about extreme energy and restlessness while gradually resulting in tremors, over-sensitivity and spasms. In large amounts, cocaine causes fever, unresponsiveness, difficulty in breathing and unconsciousness. Cocaine is often self-administered by nasal inhalation, intravenous injection and free-base smoking. It is excreted in the urine in a short time primarily as Benzoylecgonine. About Marijuana(THC) THC (∆9--tetrahydrocannabinol) is the primary active ingredient in cannabis (marijuana). When smoked or orally administered, THC produces euphoric effects. Users have impaired short term memory and slow learning. They may also experience transient episodes of confusion and anxiety. Long-term, relatively heavy use may be associated with behavioral disorders. The peak effect of marijuana administered by smoking occurs in 20-30 minutes and the duration is 90-120 minutes after one cigarette. Elevated levels of urinary metabolites are found within hours of exposure and remain detectable for 3-10 days after smoking. Analytical Specificity A drug-free urine pool was spiked with drugs at concentrations listed. The results are summarized below. Compound Concentration(ng/ml)   COCAINE Benzoylecgonine 300 Cocaine HCl 780 Cocaethylene 12,500 Ecgonine HCl   32,000   MARIJUANA (THC) 11-nor-∆9 -THC-9 COOH 50 Cannabinol 20,000 11-nor-∆8-THC-9 COOH 30 ∆8 –THC 15,000 ∆9 -THC  15,000 Configurations of the One Step -Drug Screen Test Card consists of combination of Cocaine/Marijuana(THC) drug analytes. This assay provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to the drug of abuse test result, particularly when preliminary positive results are indicated. For more information, click here.
