Do You Have a Drug Abuse Problem?

Recognize the Warning Signs and Get Help for Substance Abuse or Drug Addiction

Some people are able to use recreational or prescription drugs without experiencing negative consequences or addiction. For many others, though, substance use can be an attempt to escape from problems in their lives and has much more serious consequences. The abuse of drugs to cope with life’s problems only makes the existing problems worse and likely causes new problems to develop, leaving feelings of isolation, helplessness, or shame.

If you’re worried about your own or a friend or family member’s drug use, it’s important to know that help is available. Learning about the nature of drug abuse and addiction—why and how it develops, what it looks like, and why it can have such a powerful hold—will give you a better understanding of the problem and how to best deal with it.

Understanding drug use, drug abuse, and addiction

People experiment with drugs for many different reasons. Many first try drugs out of curiosity, to have a good time, because friends are doing it, in an effort to improve athletic performance or ease another problem, such as stress, anxiety, or depression. Use doesn’t automatically lead to abuse, and there is no specific point at which drug use moves from casual to problematic. Drug abuse and addiction is less about the amount of substance consumed or the frequency, and more about the reasons people turn to drugs in the first place as well as the consequences of their drug use. If your drug use is causing problems in your life—at work, school, home, or in your relationships—you likely have a drug abuse or addiction problem.

Why do some drug users become addicted, while others don’t?

As with many other conditions and diseases, vulnerability to addiction differs from person to person. Your genes, mental health, family and social environment all play a role in addiction. Risk factors that increase your vulnerability include:

  • Family history of addiction
  • Abuse, neglect, or other traumatic experiences
  • Mental disorders such as depression and anxiety
  • Early use of drugs
  • Method of administration—smoking or injecting a drug may increase its addictive potential 

Drug addiction and the brain

Addiction is a complex disorder characterized by compulsive drug use. While each drug produces different physical effects, all abused substances share one thing in common: repeated use can alter the way the brain functions.

    1. Taking a recreational drug causes a rush of the hormone dopamine in your brain, which triggers feelings of pleasure. Your brain remembers these feelings and wants them repeated.
    2. When you become addicted, the substance takes on the same significance as other survival behaviors, such as eating and drinking.
    3. Changes in your brain interfere with your ability to think clearly, exercise good judgment, control your behavior, and feel normal without drugs.
    4. No matter which drug you’re addicted to, the uncontrollable craving to use grows more important than anything else, including family, friends, career, and even your own health and happiness.
    5. The urge to use is so strong that your mind finds many ways to deny or rationalize the addiction. You may drastically underestimate the quantity of drugs you’re taking, how much it impacts your life, and the level of control you have over your drug use.

How drug abuse and addiction can develop

There is a fine line between regular use and drug abuse and addiction. Very few addicts are able to recognize when they have crossed that line. While frequency or the amount of drugs consumed do not necessarily constitute drug abuse or addiction, they can often be indicators of drug-related problems.

Drug abuse may start as a way to socially connect. Commonly, people try drugs for the first time in social situations with friends and acquaintances. A strong desire to fit in to the group can make it feel like doing the drugs with them is the only option.

Problems can sometimes sneak up on you, as your drug use gradually increases over time. Smoking a joint with friends over the weekend, or taking ecstasy at a rave, or cocaine at an occasional party, for example, can change from using drugs a couple of days a week to using them every day. Gradually, getting and using the drug becomes more and more important to you.

If the drug fulfills a valuable need, you may find yourself increasingly relying on it. You may take drugs to calm or energize yourself, or make you more confident. You may start using prescription drugs to cope with panic attacks or relieve chronic pain. Until you find alternative, healthier methods for overcoming these problems, your drug use will likely continue. If you are using drugs to fill a void in your life, you’re more at risk of crossing the line from casual use to drug abuse and addiction. To maintain a healthy balance in your life, you need to have positive experiences and feel good about your life without any drug use.

As drug abuse takes hold, you may miss or frequently be late for work or school, your job performance may progressively deteriorate, and you may start to neglect social or family responsibilities. Your ability to stop using is eventually compromised. What began as a voluntary choice has turned into a physical and psychological need.

Eventually drug abuse can consume your life, stopping social and intellectual development. This only reinforces the feelings of isolation that led to the drug use in the first place.

The good news is that with the right treatment and support, you can counteract the disruptive effects of drug use and regain control of your life. The first obstacle is to recognize and admit you have a problem, or listen to loved ones who are often better able to see the negative effects drug use is having on your life.

Five myths about drug abuse and addiction

Myth 1: Overcoming addiction is simply a matter of willpower. You can stop using drugs if you really want.

Fact: Prolonged exposure to drugs alters the brain in ways that result in powerful cravings and a compulsion to use. These brain changes make it extremely difficult to quit by sheer force of will.

Myth 2: Addiction is a disease; there’s nothing that can be done about it.

Fact: Most experts agree that addiction is a disease that affects the brain, but that doesn’t mean anyone is a helpless victim. The brain changes associated with addiction can be treated and reversed through therapy, medication, exercise, and other treatments.

Myth 3: Addicts have to hit rock bottom before they can get better.

Fact: Recovery can begin at any point in the addiction process—and the earlier, the better. The longer drug abuse continues, the stronger the addiction becomes and the harder it is to treat. Don’t wait to intervene until the addict has lost everything.

Myth 4: You can’t force someone into treatment; they have to want help.

Fact: Treatment doesn’t have to be voluntary to be successful. People who are pressured into treatment by their family, employer, or the legal system are just as likely to benefit as those who choose to enter treatment on their own. As they sober up and their thinking clears, many formerly resistant addicts decide they want to change.

Myth 5: Treatment didn’t work before, so there’s no point trying again.

Fact: Recovery from drug addiction is a long process that often involves setbacks. Relapse doesn’t mean that treatment has failed or that sobriety is a lost cause. Rather, it’s a signal to get back on track, either by going back to treatment or adjusting the treatment approach.

Signs and symptoms of drug abuse and drug addiction

Although different drugs have different physical effects, the symptoms of addiction are similar. If you recognize yourself in the following signs and symptoms of substance abuse and addiction, consider talking to someone about your drug use.

Common signs and symptoms of drug abuse

You’re neglecting your responsibilities at school, work, or home (e.g. flunking classes, skipping work, neglecting your children) because of your drug use.

You’re using drugs under dangerous conditions or taking risks while high, such as driving while on drugs, using dirty needles, or having unprotected sex.

Your drug use is getting you into legal trouble, such as arrests for disorderly conduct, driving under the influence, or stealing to support a drug habit. 

Your drug use is causing problems in your relationships, such as fights with your partner or family members, an unhappy boss, or the loss of friends.

Common signs and symptoms of drug addiction

You’ve built up a drug tolerance. You need to use more of the drug to experience the same effects you used to attain with smaller amounts.

You take drugs to avoid or relieve withdrawal symptoms. If you go too long without drugs, you experience symptoms such as nausea, restlessness, insomnia, depression, sweating, shaking, and anxiety.

You’ve lost control over your drug use. You often do drugs or use more than you planned, even though you told yourself you wouldn’t. You may want to stop using, but you feel powerless.

Your life revolves around drug use. You spend a lot of time using and thinking about drugs, figuring out how to get them, and recovering from the drug’s effects.

You’ve abandoned activities you used to enjoy, such as hobbies, sports, and socializing, because of your drug use.

You continue to use drugs, despite knowing it’s hurting you. It’s causing major problems in your life—blackouts, infections, mood swings, depression, paranoia—but you use anyway.

Getting help for drug abuse and drug addiction

Finding help and support for drug addiction

In the U.S., call 1-800-662-HELP to reach a free referral helpline or visit SAMHSA to find treatment services near you. In other countries, see the Resources section below for helplines and links to services.

Recognizing that you have a problem is the first step on the road to recovery, one that takes tremendous courage and strength. Facing your addiction without minimizing the problem or making excuses can feel frightening and overwhelming, but recovery is within reach. If you’re ready to make a change and willing to seek help, you can overcome your addiction and build a satisfying, drug-free life for yourself.

Support is essential to recovery

Don’t try to go it alone; it’s very easy to get discouraged and rationalize "just one more." Whether you choose to go to rehab, rely on self-help programs, get therapy, or take a self-directed treatment approach, support is essential. Recovering from drug addiction is much easier when you have people you can lean on for encouragement, comfort, and guidance.

Support can come from:

  • family members and close friends
  • healthcare providers, therapists, or counselors
  • other recovering addicts
  • people from your faith community

When a loved one has a drug problem

If you suspect that a friend or family member has a drug problem, here are a few things you can do:

Speak up. Talk to the person about your concerns, and offer your help and support without being judgmental. The earlier addiction is treated, the better. Don’t wait for your loved one to hit bottom! List specific examples of your loved one’s behavior that have you worried.

Take care of yourself. Don’t get so caught up in someone else’s drug problem that you neglect your own needs. Make sure you have people you can talk to and lean on for support. Stay safe. Don’t put yourself in dangerous situations.

Avoid self-blame. You can support a person with a substance abuse problem and encourage treatment, but you can’t force an addict to change. You can’t control your loved one’s decisions. Letting the person accept responsibility for his or her actions is an essential step along the way to recovery.


  • Attempt to punish, threaten, bribe, or preach.
  • Try to be a martyr. Avoid emotional appeals that may only increase feelings of guilt and the compulsion to use drugs.
  • Cover up or make excuses for the drug abuser, or shield them from the negative consequences of their behavior.
  • Take over their responsibilities, leaving them with no sense of importance or dignity.
  • Hide or throw out drugs.
  • Argue with the person when they are high.
  • Use drugs with them.
  • Feel guilty or responsible for another's behavior.

When your teen has a drug problem

Discovering your child uses drugs can generate fear, confusion, and anger. It’s important to remain calm when confronting your teen, and to only do so when everyone is sober. Explain your concerns and make it clear that your concern comes from a place of love. It’s important that your teen feels you are supportive.

Warning signs of teen drug abuse

While experimenting with drugs doesn’t automatically lead to drug abuse, early use is a risk factor for developing more serious drug abuse and addiction. Risk of drug abuse also increases greatly during times of transition, such as changing schools, moving, or divorce. The challenge for parents is to distinguish between the normal, often volatile, ups and downs of the teen years and the red flags of substance abuse. These include:

Having bloodshot eyes or dilated pupils; using eye drops to try to mask these signs

Skipping class; declining grades; suddenly getting into trouble at school

Missing money, valuables, or prescriptions

Acting uncharacteristically isolated, withdrawn, angry, or depressed

Dropping one group of friends for another; being secretive about the new peer group

Loss of interest in old hobbies; lying about new interests and activities

Demanding more privacy; locking doors; avoiding eye contact; sneaking around

Five steps parents can take:

    1. Lay down rules and consequences. Your teen should understand that using drugs comes with specific consequences. Don’t make hollow threats or set rules that you cannot enforce. Make sure your spouse agrees with the rules and is prepared to enforce them.
    2. Monitor your teen’s activity. Know where your teen goes and who he or she hangs out with. It’s also important to routinely check potential hiding places for drugs—in backpacks, between books on a shelf, in DVD cases or make-up cases. Explain to your teen that this lack of privacy is a consequence of him or her having been caught using drugs.
    3. Encourage other interests and social activities. Expose your teen to healthy hobbies and activities, such as team sports and afterschool clubs.
    4. Talk to your child about underlying issues. Drug use can be the result of other problems. Is your child having trouble fitting in? Has there been a recent major change, like a move or divorce causing stress?
    5. Get help. Teenagers often rebel against their parents but if they hear the same information from a different authority figure, they may be more inclined to listen. Try a sports coach, family doctor, therapist, or drug counselor.
