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. “How long does marijuana stay in the system?” you have to realize that it’s very unlikely that you’ll be able to get a usable answer. The most common detection period of time on a urine marijuana drug test is anywhere from 3-30 days, depending on metabolism and the amount of marijuana smoked. If a person smokes it occasionally it will remain in their system for up to 10 days. If marijuana is smokes on a regular basis it will stay in their system for as long as 45 days, and if smoke marijuana at a constant pace, it can stay in the body for 90 days, since Marijuana is fat soluble. It stores in the fat cells of the body, the brain, the liver, the kidneys, in other words the major organs.

 

The main metabolite excreted in the urine is 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid (Δ9-THC-COOH). The One Step THC Marijuana Drug Testing kits yields a positive result when the concentration of THC-COOH in urine exceeds 50 ng/mL. This is the suggested THC Test screening cut-off for positive samples set by the Substance Abuse and Mental Health Services Administration (SAMHSA). "Passive smoking" of marijuana is not an acceptable excuse at the 50 ng/ml level, since only in extreme circumstances can a non-smoker absorb enough pot to test urine positive (e.g., being stuck in a closet full of heavy smokers for hours). However, passive exposure may result in positive tests at 25 ng/ml or lower. The use of this onsite marijuana drug test kits is comon on workplace, clinical and home drug test markets.
