For most of the laboratory tests and the instant tests like the blood, urine, saliva and the hair tests, 50 nanograms per ml is defined as a presumptive positive by SAMHSA. In the beginning this number used to be 20ng/ml, but resulted in too many false positives and hence it is increased to 100ng/ml. However, again in 1995, the cutoff is lowered back down to 50ng/ml since it was believed that excessive drinking of water could bring the metabolites in urine below 100ng/ml.

For this cutoff, if the specimen screens non negative for THC, then it is sent through a Gas chromatograph/Mass Spectrometer(GC/MS) for specific metabolite tripping the immunoassy screening. For that the cut off is set at 15 ng/ml, and it is used as a confirmation for a positive on the drug test.

In a simpler way, the initial screening cutoff level is 50 ng/ml and the GC/MS cutoff is 15 ng/ml. The elimination half life for the drug marijuana ranges from 14-38 hours. At the initial cutoff the regular user will remain positive for 7-30 days after cessation and for confirmation level the daily user will be positive as long as 15 weeks.

Research study by the Yale university found that nicotine present in tobacco binds to specific receptors present on the brain which promote addiction. It was found that nicotine also binds to other receptors present on the hypothalamus region. These receptors are involved in regulation of appetite.

The study included research on mice using nicotine and also other drug called cytisine, which like nicotine also binds to the receptors of appetite regulation. It was found that, when nicotine was given to the mice which do not have these appetite regulating receptors, there was no weight loss. The mice were found to be like the normal mice. This suggested that the nicotine binds to these appetite regulating receptors.

Among smokers, these receptors are occupied by the nicotine. So, they do not feel like eating. Where as, when they quit smoking, the receptors are free and not bound by nicotine. As a result, they are not restricted to stop eating. This is the main reason for increasing weight among people who quit smoking.

It is very silly to be away from quitting the habit thinking of the weight gain. Smoking causes cancer, heart attacks and many other ailments which are more serious and life-threatening than the weight gain.
