At first, the patient may choose to take a drug because he or she likes how it feels. You may think you can control how much and how often you take it. But over time, the drug changes the way the brain works. These physical changes can persist for a long time. They cause a person to lose control of themselves and can lead them to engage in harmful behaviors.
Addiction is a state that affects a person's brain and behavior. When addicted to drugs, the person will not be able to resist the urge to use them, no matter how harmful the drug may be.
Addiction is not just heroin, cocaine or other illegal drugs. Patients may be addicted to alcohol, nicotine, opioid pain relievers, sleeping and anti-anxiety medications, and other legal substances.
1. Addiction and abuse
Substance abuse is when a sick person uses legal or illegal substances in ways they should not. The patient may take more than the usual dose or use someone else's prescription. Patients may abuse drugs to feel good, relieve stress, or avoid reality. But often, people can change this unhealthy habit or stop using it altogether.
Addiction is when the patient can't stop. Even though it puts the patient's health in jeopardy, it causes financial, emotional and other problems for the patient or his or her loved ones.

Early drug use increases a person's likelihood of addiction. Remember, narcotics change the way the brain works — and this can lead to addiction and other serious problems. So, early stopping drug or alcohol use can help reduce these risks.
The risk of drug use increases greatly during the transition. For an adult, divorce or job loss can increase the risk of drug use. For a teen, risky times include moving house, divorce in the family, or transferring schools. As children move from elementary school to middle school, they face challenging new social, family, and academic situations. Usually in this stage, children are exposed to substances such as tobacco and alcohol for the first time. By the time they enter high school, teens may experience more drug use, older teens who use drugs, and drug-based social activities. As individuals leave high school and live more independently, such as in college or work, they may be exposed to drug use more easily when they leave the protection of family and school. .

Young people's desire to try new things and become more independent is good, but it can also increase a teen's tendency to try drugs.

This limits the ability to accurately assess the risks of drug testing in young adults. teenagers and makes them more susceptible to peer pressure.
Because the brain is still developing, drug use at this age is more likely to disrupt brain function in areas important for motivation, memory, learning, judgment and behavioral control.
