It's not as easy as just choosing to quit.
Many people don't understand why or how other people become addicted to drugs. They often mistakenly think that those who use drugs lack moral principles or willpower and that they could stop their drug use simply by choosing to. In reality, drug addiction is a complex disease, and quitting usually takes more than good intentions or a strong will. Alcohol and other drugs changes the brain in ways that make quitting hard, even for those who want to. Fortunately, researchers know more than ever about how alcohol and other drug abuse affects the brain and have found effective treatments that can help people recover from addiction and lead productive lives.
