How to tell if Someone is on Drugs

How do you tell if someone is on drugs? There are many different signs to look for when identifying if someone is on drugs. Drug addiction is a disease that can affect anyone. It does not discriminate against race, gender or economic status. Also referred to as substance use disorder, it is a mental illness that impacts the brain and behavior, leading to the inability to control the use of legal or illegal drugs and medicines. The most common types of drug addiction include substance abuse and alcohol abuse.

There is no one-size-fits-all when it comes to the typical characteristics of a person who is on drugs or is a drug addict. They can all act and appear different. Signs of drug use vary greatly based on the individual and the substance they are using. Signs of drug use can be physical, behavioral and psychological.

Drug addiction usually starts with experimental use of recreational drugs in a social setting. This is very common for young people. In these cases, drug use will become more and more frequent. Young people are more likely to display typical behaviors of drug use while going through adolescence. But sometimes it isn’t always obvious. For young people, it could just be stress, experiencing issues at work or school, experiencing mental health problems or just having a more difficult time sleeping.

Signs of Drug Use by the Type of Drug

Signs of Alcohol Use

Alcohol is the most widely abused substance in the US due to ease of accessibility and availability. It is not a controlled substance and there is less stigma behind drinking alcohol because it is also used in many religious and cultural settings. It is a depressant drug that slows down the central nervous system and results in symptoms like calmness and lethargy.

For those who have become dependent on alcohol, it may be hard to stop drinking even after one or two drinks. This person may even prefer to drink alone or at odd times, not typical for social drinking. Those who abuse alcohol will continue to consume the drug even if it causes strain on relationships and will continue to drink despite negative consequences. They will even continue to drink despite the consequences to their physical health and emotional well-being.

Signs of Marijuana Use

Marijuana is now openly sold in many places, depending on the state. It is also a very commonly used substance among people of all ages. Some common signs of marijuana use include increased appetite and weight gain. Users might experience slower reaction times, slower cognition and difficulty with memory. In cases of abuse, a user may experience a sense of paranoia and suspicion. Marijuana use can result in bloodshot eyes, droopy eyelids and a more mellow demeanor.
