Weed, pot, Mary Jane, herb, dope, grass. Marijuana goes by many names, but no matter what you call it, it remains the number one illegal recreational drug in the United States. Though some states have laws permitting the use of marijuana for medicinal purposes, possession and distribution of the drug is still largely considered a crime. Yet, regardless of whether or not any drug is legal, abuse is still possible and always very harmful. Despite arguments for and against its use, marijuana users may not be immune to addiction.
A by-product of the Cannabis sativa plant, marijuana has been used by various cultures for centuries for medicinal and spiritual uses. The ancient .Aryan Indians used a form of cannabis in tribal rituals, and the drug has been known to treat discomfort from headaches, glaucoma, and nausea resulting from chemotherapy. Marijuana also has a strong association to pop culture.
THC or Tetrahydrocannabinol (9-tetrahydrocannabinol) is the primary active ingredient in cannabis (marijuana). When ingested or smoked, it produces euphoric effects. THC may promote a prolonged feeling of relaxation and/or disorientation in users, that "stoned" feeling that encourages sleepiness and increases the appetite (also known as "getting the munchies"). Enjoying such a euphoria may encourage some to continue using the drug on a regular basis.
.Signs that a person may be abusing marijuana might include:
- Sudden mood changes, depression and listlessness
- Redness in the eyes
- Problems with concentration, short-term memory loss
- Change in appearance
- Marijuana has a distinct odor that lingers in clothes and hair when smoked
.Users have impairment of short-term memory and a reduced ability to learn. Also, it may cause transient episodes of confusion, anxiety, or even toxic delirium. Long term effects are uncommon, but relatively heavy use may be associated with behavioral disorders. Marijuana is used by millions of users every year, and that number continues to grow as more and more evidence uncovers its positive medical effects and disproves the negative publicity the drug receives. Marijuana has been proved to be less harmful then alcohol and cigarettes. With the increase of marijuana smokers the increase in the cover up and detoxification of marijuana increases as well. This leads to more and more urinary cleansers being marketed and used.
The most popular employer and government drug test for THC is urine test. Marijuana is absorbed into our fatty tissues and the liver, and eventually end up in our urine. Elevated levels of the urinary metabolite 11-nor-9-tetrahydrocannabinol-9-carb oxylic acid are found within hours of exposure and remain detectable for 3-10 days after smoking.
The THC / marijuana drug test is based on the principle of the highly specific immunochemical reactions between antigens and antibodies, which are used for the analysis of specific substances in biological fluids. The sensitivity is 50 ng/ml of THC marijuana.
