Drugs are everywhere--on our streets, in our homes, and in our schools--but straight facts about drugs are not. Drugs: The Straight Facts fills this void with candid discussions that emphasize a historical and scientific approach to learning about drugs, their use, and their effect on the user's health. Explore the history of marijuana throughout the ages, the neurochemical pathway of the psychoactive component of marijuana, and current trends and attitudes toward its use.

Although some experts hypothesized that prior parental use of marijuana might influence teenagers, research has shown that baby-boomer parents (who grew up in a period of high marijuana use) did not account for the different rates of teenage marijuana use. In addition, a 2001 survey by the Center on Addiction and Substance Abuse (CASA) revealed that “hands-on” parents who have established rules and

Many recent scientific reports refer to the C. sativa plant; therefore, we will use “cannabis,” “hemp plant,” and “marijuana” inter-changeably with C. sativa. There are differences among these plants in the leaves, stems, and, most important, the resin. The resin content determines the the effective strength of a hemp preparation; yet the resin amount can vary greatly from plant to plant. Hashish, a more concentrated form

As a result, THC accumulates in fat cells. Although many drugs enter the body’s fat cells in a similar fashion to marijuana, most drugs exit the body quickly. Since THC exits the fat cells slowly, traces of THC are detectable in the body for days or weeks after inhaling or ingesting it. Several studies indicate

us look at a drug that acts like an antagonist that blocks the inhibitory action of a neurotransmitter. This blockade could upset the balance of normal neuronal function by allowing excitatory activity to become the more dominant neuronal action. In a myriad of ways, these types of neuronal imbalances can be translated to the physical and psychological effects that are seen after using drugs such as marijuana. In this manner, we can see that the actions of agonists and antagonists can be quite

receptors. It may be possible that those who do not produce many of these receptors are the ones who find marijuana, opiates, or other drugs particularly pleasant and may come to rely upon them for this externally produced “high.” This is especially evident in those individuals with depression, schizophrenia, and other mental disorders. It is known that people with these types of mental illnesses actually have imbalances in their central neurotransmitter systems. These imbalances can be
