The Health Effects of Commonly Used Drugs

One of the myths floating around about drug abuse is if it can be or usually is used as a medication, it's not harmful. Contrary to what some believe, the abuse or nonmedical use of any drug can have long-lasting effects on your health.

Besides alcohol (which has its own set of health effects), the following are the most commonly abused drugs in the United States, in order of popularity, and how they can affect your health.

Marijuana is the most commonly used illicit drug in the United States. When smoked, it begins to affect users almost immediately and can last for one to three hours. Users claim that smoking marijuana is not harmful, but scientific evidence proves otherwise.

According to the National Survey on Drug Use and Health (NSDUH), the second most popular drugs of abuse in the U.S. are psychotherapeutics including pain relievers, tranquilizers, stimulants, and sedatives. This involves the nonmedical use of prescription drugs, over-the-counter drugs, and drugs that may be manufactured illegally, such as methamphetamine and ecstasy.

Approximately 2.1 million people in the U.S. use cocaine, making it the third most abused category of drug. Cocaine can be snorted, injected and even smoked in some forms of the drug. In all cases, cocaine is a strong central nervous system stimulant which affects the brain.

Each month, more than a million people in the U.S. use hallucinogens such as LSD, PCP, Ketamine, and DMX, according to NSDUH. Hallucinogens disrupt a person's ability to think and communicate rationally, or even to recognize reality, sometimes resulting in bizarre or dangerous behavior.

Of all the illicit drugs available on the market today, heroin is the least commonly abused, with only an estimated 200,000 current users in the United States. That's probably because it is the most addictive of all the street drugs. Whether injected, snorted or smoked, heroin will begin to affect the body's central nervous system almost immediately after it is used.
