1. Well, have you smoked marijuana recently?
2. yeah they are, and they are approved by the FDA
3. They are very accurate since they use the same cut-off level that SAMHSA estsblih which is 50ng "THC (tetrahydrocannabinol) is a hallucinogenic, sedative drug considered the primary active compound of the 400+ chemicals in the cannabis sativa plant. While there is some legal use of THC, such as the prescription Marinol (Dronabinol) used for wasting in cancer/HIV patients, most THC drug test positives are the result of illicit use. Marijuana is the number 1 illegal drug in the US. When smoked or orally administered, THC produces euphoric effects. Users have impaired short-term memory and slowed 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. The main metabolite excreted in the urine is 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid (Δ9-THC-COOH). The One Step Multi-Drug, Multi-Line Screen Test Device yields a positive result when the concentration of THC-COOH in urine exceeds 50 ng/mL. This is the suggested screening cut-off for positive samples set by the Substance Abuse and Mental Health Services Administration (SAMHSA). The use of this onsite marijuana drug test is comon on workplace, clinical and home drug test markets." Next time you wan't to save money and get more than one go to www.medicaldisposables.us
