Marijuana is most commonly tested drug in united states and in other countries as well. It is more likely to stay in our system for weeks or months. It is considered as one of the least harmful drugs and the complete metabolic activity and diffusion of drug depends on the metabolic rate of human body. Marijuana metabolizes into THC, abbreviated for 11-nor-delta9 tetrahydrocannibinol-9-carboxylic acid, which is a primary metabolite of marijuana. The half-life calculation of THC gives the total idea of drug absorbed by the body. It also gives the idea of its clearance in the body as half-life is the length of time that takes to lose half of the THC from the body. Most of the drugs are washed out of our body within few weeks which may encourage people appearing for drug tests. However, marijuana and THC remains in the system for the month or so, which is one of the factors that might force people to quit taking it. There are five primary type of drug tests categorized on the basis of type of samples used. They may include - urine, saliva, hair, sweat and blood based drug tests. Out of these, saliva, hair ans sweat based tests are increasingly being used as they involve the least intrusive sampling procedure. For testing the body THC levels, various kits have been designed which provide a quick test for presence of marijuana or its metabolites. Many companies ich are easy to use, home based tests that allow easy monitoring of drug abuse. These testing kits happen to be FDA approved, 95-99% accurate and simple to administer.
