Gas-liquid chromatography (GLC) finds many applications outside the chemistry laboratory. If you ve ever had an emissions test on the exhaust system of your car, GLC was almost certainly the analytical method used. Pollutants such as carbon monoxide and unbumed hydrocarbons appear as peaks on a graph such as that shown in Figure 1.7. A computer determines the areas under these peaks, which are proportional to the concentrations of pollutants, and prints out a series of numbers that tells the inspector whether your car passed or failed the test. Many of the techniques used to test people lor drugs (marijuana, cocaine, and others) or alcohol also make use of gas-liquid chromatography. [Pg.7]

Marijuana, or Cannabis sativa, is a weed-like plant that grows in temperate and tropical climates. Although best known for its psychoactive properties and use as a recreational drug, marijuana has also been used historically for industrial and medicinal purposes not related to its mind altering abilities. [Pg.9]

From 1999 to 2000, total drug-related ED episodes increased 20 percent for adolescents. Out of 63,448 mentions of drugs, marijuana was mentioned 15,683 times. [Pg.47]

If marijuana were moved to Schedule II, physicians would be able to legally prescribe marijuana without fear of losing their medical licenses. As a Schedule II drug, marijuana would be prescribed under the same strict regulations that govern the medical prescription of morphine and cocaine. In 1989,... [Pg.91]

Marijuana has a long history in human civilization. The plants, from which the frber hemp and the drug marijuana come, have been grown all over the world for thousands of years. Humans have found many uses for this plant, but it is its use as a drug that makes it controversial and illegal in most countries. [Pg.11]

A second group of states that enacted criminal laws against the use of marijuana were in the northeastern part of the country. In these states there were few Mexicans, but northeastern residents had heard about the influx of Mexican immigrants out west and about the drug marijuana. These states had just begun to get the morphine addiction problem under control and feared that addicts, cut off from morphine, would substitute some other drug that was not yet controlled. In the absence of any research or medical information, marijuana seemed like a possible candidate for this substitution. So even though marijuana use was virtually unknown in the Northeast at that time, these states also outlawed it. [Pg.43]

In terms of illicit drugs, marijuana certainly generates the most controversy. As was seen in Chapter 3, there have been and are decriminalization initiatives domestically and abroad and 11 states have legalized marijuana for medical purposes. There are well-financed efforts to legalize marijuana for personal possession. For example, the Marijuana Policy Project, a nonprofit organization with thousands of members, has sponsored ballot initiatives in Nevada to legalize the possession of small amounts of marijuana, and the activities of the Drug Policy Alliance on marijuana were mentioned in Chapter 3. [Pg.71]

THC effects on driving-related skills and driving performance. To really understand the effects of THC on driving, we must turn to experimental studies. The experimental paradigm enables us to control for the effects of potentially confounding variables, and to systematically vary the drug (marijuana) dose and observe its effects. [Pg.479]
