Marijuana (THC) Drug Test

Marijuana (THC)THC (Δ9--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 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).

THC Drug Test

The drug marijuana refers to the dried leaves, flowers, stems, and seeds from the Cannabis sativa or Cannabis indica plant. The plant contains the mind-altering chemical THC and other similar compounds. The amount of THC in marijuana has been increasing steadily over the past few decades. For someone who is new to marijuana, this may man exposure to higher THC levels with a greater chance of a harmful reaction. Higher THC levels may explain the rise in emergency room visits involving marijuana use. Higher THC levels may also mean a greater risk for addiction if people are regularly exposing themselves to high doses.

People use marijuana by smoking, eating, drinking, or inhaling it. Smoking and vaping THC-rich extracts from the marijuana plant (a practice called dabbing) is on the rise. It's unlikely that a person will fail a marijuana drug test or get high from passive exposure by inhaling secondhand marijuana smoke. There aren't any reports of teens and adults dying from using marijuana alone, but marijuana can cause some very uncomfortable side effects, such as anxiety and paranoia and, in rare cases, extreme psychotic reactions.

Marijuana is the most commonly used illicit drug in the United States. Its use is widespread among young people. In 2015, more than 11 million young adults age 18-25 used marijuana in the past year. Source -

Some states have approved "medical marijuana" to ease symptoms of various health problems. The U.S. Food and Drug Administration (FDA) has not approved the marijuana plant as medicine. However, there have been scientific studies of cannabinoids, the chemicals in marijuana. This has led to two FDA approved medicines. They treat nausea caused by chemotherapy and increase appetite in patients who have severe weight loss from HIV/AIDS. Scientists are doing research with marijuana and its ingredients to treat many diseases and conditions. Source -

Symptoms of Use

These are some effects of marijuana use:

  • Feeling of joy, relaxation
  • Increased sight, hearing, and taste perceptions
  • Increased Appetite
  • Loss of coordination, making it difficult, even dangerous, to perform tasks like driving a car
  • False sense of time
  • Trouble thinking and problem solving that can also effect driving
  • Unable to tell the difference between oneself and others
  • Anxiety or panic reactions or being overly suspicious and distrustful

Signs of marijuana use include:

  • Being dizzy
  • Having trouble walking
  • Being silly and giggly for no reason
