It is well known that using illicit drugs or abusing controlled substances is harmful to the body and brain; however, nearly 8,000 Americans over the age of 11 abused drugs for the first time each day in 2013.
In addition, close to 25 million Americans were considered to be current illicit drug users, which means that they had used drugs within 30 days of the National Survey of Drug Use and Health (NSDUH) being conducted. Regardless of all of the negative consequences of drug abuse, drugs can make users feel good and temporarily relieve feelings of stress, depression, and other difficult emotions, which encourages people to keeping taking them.
Drugs interfere with the way the brain processes motivation and pleasure, making it harder and harder to remove them from the bloodstream without professional help. Illicit drugs and controlled substances also disrupt normal cognitive functions such as decision-making, learning, and memory processes. Memory loss may be a common side effect of drug abuse.
