Drug misuse is using drugs in a way that harms you or that leads you to harm
others. You can misuse illegal drugs, prescription drugs, or
When you misuse

or operating machines. Or drugs may cause problems in your

of the following can happen:
Drug dependence is a disease. It's not a weakness or a
lack of willpower. It's your choice to begin using a drug. But as you use it
more, your brain begins to change. This change can lead to a craving to use the
drug, and this can influence how you act.

drugs. The behavior could be because of work or school stress, or it could be a
depression or another medical problem. But behavior

signs of drug misuse and dependence include:
Drug problems may
be diagnosed at a routine doctor visit or when you see your doctor for a health
or social problem linked to drug use, such as anxiety,
depression, or family conflict. If a partner or friend
thinks you have a drug problem, he or she may urge you to see your
Your doctor will ask questions about your symptoms and
past health. He or she will do a physical exam and sometimes a mental
medicine, therapy, and support groups.
The first step in treatment is to quit using drugs. You may need medical care to manage withdrawal symptoms when you first quit. Some people call this detoxification, or detox.
After you stop using drugs, you focus on staying drug-free. Most people receive
some type of therapy, such as group counseling. You also may need medicine to
help you stay drug-free.
When you have stopped using drugs, you
have taken the first step toward
recovery. To gain full recovery, you need to take
steps to improve other areas of your life, such as learning to deal with your
work, family, and living situation in healthy ways. This makes it easier to
If you feel that you have a drug problem, get help. You can visit a
doctor or go to a self-help group. The earlier you get help, the easier your
recovery will be for you and your family.
Helping someone who has a
drug problem is hard. If you are
"covering" for the person, you need to stop. For
example, don't make excuses for the person when he or she misses work.
You may be able to help by talking to the person about what his or her
drug use does to you and others. Talk to the person in private, when he or she
isn't using drugs or alcohol and when you are both calm. If the person agrees
to get help, call for an appointment right away. Don't wait.
Learning about drug use and dependence:
Most of the time,
drug misuse starts with casual use. People don't use drugs because they want to be
addicted. Drugs can make
you feel good for a while. They may make you feel energetic, self-confident,
and powerful. You may take a drug to reduce
anxiety or to help you forget a problem.
changes your brain and how it works. If you continue to use drugs,
you may develop strong cravings for them, and it may get harder to say "no" to further use. At the same time, you may begin to lose interest in
activities you always enjoyed. This is because you may feel that they are not
as enjoyable as using drugs. You may then become dependent.
Not everyone who uses drugs misuses them or becomes dependent. Other
things that influence whether this happens include your
genes, family, friends, and life situations. For more information, see
What Happens and What Increases Your Risk.

in your behavior than to have physical symptoms.

aging. Older adults often take more medicines, such as sleep medicines and
painkillers, that can lead to dependence.
When you are dependent on a
drug and you stop using it, you may have physical symptoms known as
withdrawal. These symptoms differ for each drug. They can include feeling sick to your stomach,
vomiting, having belly pain, sweats, nervousness and shaking, and
You may not feel that using drugs is a
problem. Maybe you feel that you are a casual user because you use drugs only
now and then. You may feel that you can stop using drugs at any time.
But drug use quickly can become a habit, and for many people it may lead
a substance use problem and
addiction. You may begin to use drugs without thinking
about how drugs can harm you and those you care about.

health problems, such as:
Drugs also can lead to problems with thinking and
remembering. They can affect judgment, decision-making, emotions, and learning.

ways. Drugs that can cause harm include:

sexually transmitted infections (STIs).

Drug use also can lead to problems with
your partner, family, or friends. You and

them, and they may be angry at you. You may do poorly at work or in school, or
you may even quit. You also can have legal problems, like being arrested for
driving while on drugs or for using or selling drugs.

Watchful waiting is a
wait-and-see approach. If you get better on your own, you won't need treatment.
If you get worse, you and your doctor will decide what to do next.
Watchful waiting is not a good choice for drug misuse and dependence. If
you have a drug problem, or if you believe that your health or other areas of
your life are being affected by drugs, you need to take steps to stop using

Your doctor will ask you questions about your symptoms and
past health and will do a
physical exam. If your doctor thinks you have a drug
problem, he or she may ask about
current and past drug use. He or she also may ask if it's okay to give you a test to check for drug use,
such as a urine or blood test.

tests to look for health problems related to drug use. These may include
hepatitis C, or
If you and your doctor agree that
you have a drug problem, your doctor probably will refer you to a specialist in
drug use or dependence.
People who use
drugs also may have mental health problems. These include
anxiety disorders, or
post-traumatic stress disorder (PTSD). If your doctor
thinks this may be true for you, he or she may do a
mental health assessment.
If you use
drugs and have a mental health problem, it's called a
dual diagnosis. If you
treat only one problem, treatment may not work well. When you treat both
problems, you have a better chance of a full
recovery and less chance of using drugs again.

good reasons to quit drugs. Staying drug-free is a lifelong
process that takes commitment and effort.
You might start with your family doctor, or your doctor may recommend that you
enter a treatment facility. A friend could bring you to a self-help group, such
as Narcotics Anonymous, or you might walk into a clinic that deals with drug
You may have a treatment team to help you. This team may include
social workers, nurses, and a case manager. A case
manager helps plan and manage your treatment.
You may be asked
questions about your drug use, health problems, work, and living situation. Be
open and honest to get the best treatment possible. Your team may
write a plan, which includes your treatment goals and ways to reach
those goals. This helps you stay on track.
Your doctor may decide you need
medical care to manage withdrawal symptoms when you first quit using drugs. This is sometimes called detoxification, or detox.
People who are dependent on
drugs often have to go to a hospital or treatment facility. Detox usually is
done under the care of a doctor, because withdrawal can be
dangerous without medical care. A doctor may prescribe medicines to help with withdrawal symptoms.
Treatment for a drug problem usually
involves one or more types of therapy.
Treatment usually includes going to a support group, such
as going to Narcotics Anonymous (NA) meetings. Your family members might also
want to attend a support group such as Nar-Anon.
You may take medicines to help you quit
or to help you overcome
withdrawal symptoms. Medicines often are used for
opioid drugs like heroin or certain painkillers.
Medicines that can help you include methadone (such as Dolophine) or naltrexone (such as ReVia).
Treatment programs can be
outpatient, inpatient, or residential. They offer similar therapies. Your
treatment team can help you decide which type of program is best for you.
Some treatment programs give rewards, called vouchers,
when you stay off drugs. The rewards may get bigger when you go for a long time
Many programs give regular drug tests while you go
through treatment. Knowing that you will be tested can make you more likely to
resist your cravings.

often have other problems. They may need other
treatments, or other resources may be available to help them with the drug

Stopping drug use is very hard.
It's normal to have setbacks, even years later. Very few people succeed the
first time they try. A lapse or
relapse is likely.
A lapse or relapse doesn't mean that you or your treatment has

If someone you care about has had a drug problem, you know how hard it
can be. You know how living or dealing with someone who has a drug problem can
