Drug addiction is a major problem in the United States and around the world. It's an illness that can result in serious health problems, including death. If you think someone you know may be addicted to drugs, here are some signs and symptoms to watch for:
1. Change in behavior. Someone with drug addiction may start using drugs more often or in greater quantities, or may begin spending more time using drugs than usual. They may become isolated from friends and family, and might have trouble concentrating or making decisions. For more information about the problems of drug addiction you can explore this link.
2. Withdrawal symptoms. When someone becomes addicted to drugs, their body begins to develop a tolerance to its effects. This means they need increasingly larger doses of drugs to get the same effect as before. As a result, they might experience withdrawal symptoms when they try to stop using drugs – such as intense cravings, anxiety, sleeplessness, and mood swings.
3. Increased use even when it's not necessary. People who are addicted to drugs often continue using them even if it isn't necessary – for example, because they're curious about how the drug feels or because they're trying to avoid withdrawal symptoms.
4. Changes in mental health. Someone with drug addiction might experience changes in their moods or behavior that aren't normal for them . They might become depressed, anxious, or aggressive. They might also have problems sleeping or concentrating.
5. Negative changes in physical health. Drug addiction can cause serious health problems, including weight loss or gain, high blood pressure, and heart disease. It can also lead to liver damage, pneumonia, and psychosis.
