Marijuana Impair guide?

E 'against the law to drive under the influence of marijuana. It was always thought that cannabis, like alcohol, impairs the perception, coordination, reflexes and conviction of the safe operation of a motor vehicle. And of course there were government studies have been concerned by the question: Marijuana on driving?

It 's interesting, but the results are not necessarily public support ....

First, the Department of CaliforniaCourt concluded that marijuana definitely affects psychomotor skills that are functionally related to driving and driving may be affected, particularly at high doses or for novice users. "Marijuana and alcohol: a study of driver behavior," Office of California Highway Safety Project No. 087902 (September 1986).

Contrary to these results, but two studies by the federal government. The U.S. Department of Transportation has conducted research with a fully interactiveMortgage on the effects of alcohol and marijuana, alone or in combination, the behavior of drivers tested and performance. Although alcohol was found consistently and clearly lead to a degradation of marijuana was only an occasional effect. Furthermore, there was little evidence the interactions between alcohol and marijuana. accidents and fines increased reliably with alcohol, but found no marijuana or alcohol affects of marijuana combination. "The effects of alcohol on the driver-controlledBehavior in a driving simulator, Phase I ", DOT-HS-806 to 414

A recent report titled "Marijuana and actual performance, dot-HS-808-078, noted that" THC is not a drug profoundly influence .... It clearly affects the processing of information in a variety of studies laboratory tested, but not the magnitude, the individual capacity to control, if it is motivated and able to move east.

The study concluded that: "... An important objective of the practiceStudy was to determine whether the degree of driving impairment is measured by calculating the actual concentration of THC measured in plasma or yield potential in the street, "sobriety" tests tracking Ability or hand and posture stability are planned. The results reported, as already pointed out that none of these measures predict accurately the changes in actual performance under the influence of THC ...".

The researchers found that this is not possible, something of a diplomaalteration of the driver based on plasma concentrations of THC and THC-COOH in a single sample "defined. Note:" THC stands for delta-9-tetrahydrocannabinol, the intoxicating principle of marijuana. THC has been implemented very quickly by the body inert metabolites, which can remain in the body for hours or even days. It is these metabolites that the blood test to measure because of the police and DUI arrests.

In other words, (1) fireworks may not have the ability to drive at all,and (2) the blood of "evidence" that measures an inactive substance that may have been for days.
