Drug Abuse and Addiction:
Signs, Symptoms, and Effects
The path to drug addiction begins with the act of taking drugs. Over time,
a person's ability to choose not to take drugs is compromised. This in large
part is a result of the effects of prolonged drug use on brain functioning,
and thus on behavior. Addiction, therefore, is characterized by compulsive,
drug craving, seeking, and use that persists even in the face of negative
consequences.

What is drug abuse and substance abuse?
Drug abuse, also known as substance abuse, involves the repeated and excessive
use of a drug to produce pleasure or escape reality—despite its destructive
effects. The substances abused can be illegal drugs such as marijuana and
cocaine, or legal substances used improperly, such as prescription
drugs and inhalants like nail polish or gasoline. But whatever the
drug of choice, substance abuse can be identified by the maladaptive way
in which it takes over the user's life, disrupting his or her relationships,
daily functioning, and peace of mind.
For those in the grips of drug abuse and addiction, their drug controls them, not the other way around. As the director of The National Institute on Drug Abuse states, “uncontrollable, compulsive drug seeking and use, even in the face of negative health and social consequences” is the essence of drug addiction. Drug addiction can be physical, psychological, or both. The Substance Abuse and Mental Health Services Administration refers to psychological dependence as “the subjective feeling that the user needs the drug to maintain a feeling of well-being." Using a drug to numb unpleasant feelings, to relax, or to satisfy cravings are examples of psychological addiction. On the other hand, physical dependence refers to the physiological effects of drug use. Physical addiction is characterized by tolerance—the need for increasingly larger doses in order to achieve the initial effect—and withdrawal symptoms when the user stops.
What are the signs and symptoms of drug addiction
and abuse?
The more drug use begins to affect and control a person's life, the more
likely it is that he or she has a drug problem. Unfortunately, substance
abusers are often the last ones to recognize their own symptoms of dependence
and addiction. If you suspect that a friend or loved one is abusing drugs,
it's important to remember that drug abusers often try to conceal their symptoms
and downplay their problem. But there are a number of warning signs you can
look for:
Inability to relax or have fun without doing drugs.
Sudden changes in work or school attendance and quality of work or grades.
Frequently borrowing money, selling possessions, or stealing items from employer, home, or school.
Angry outbursts, mood swings, irritability, manic behavior, or overall attitude change.
Talking incoherently or making inappropriate remarks.
Deterioration of physical appearance and grooming.
Wearing sunglasses and/or long sleeve shirts frequently or at inappropriate times.
No longer spending time with friends who don't use drugs and/or associating with known users.
Engaging in secretive or suspicious behaviors, such as making frequent trips to the restroom, basement, or other isolated areas where drug use would be undisturbed.
Talking about drugs all the time and pressuring others to use.
Expressing feelings of exhaustion, depression, and hopelessness.
Using drugs first thing in the morning.

If you are abusing drugs, you may be in denial about the magnitude of the problem or the negative impact it's had on your life. However, if you feel you should cut back or feel guilty about your drug use, you may have a substance abuse problem. Other warning signs include criticism from friends and family regarding your drug use and the need to use drugs in order to get through the day.

What are the signs and symptoms of drug use and
abuse in teens?
There are several telltale signs of possible drug use or abuse in teenagers.
The challenge for parents is to distinguish between the normal, sometimes
volatile ups and downs of adolescent development and the red flags of substance
abuse.
According to the National Drug Intelligence Center, sudden or extreme changes in personality, appearance, school performance, or extracurricular activities may indicate teen drug use. For example, a previously well-behaved, respectful teenager may become emotionally volatile, hostile, or violent. A teenager who is abusing drugs may also withdraw from family and friends, drop previously-enjoyed activities, and neglect schoolwork. Secretive behavior and lying to cover up drug use is also common. In addition, teen drug users may steal, ask for money, or sell valuable possessions in order to support their habit.
Warning Signs of Teen Drug Use |
Negative changes in schoolwork, missing school, or
declining grades. |

Why do people use and abuse drugs?
There are many reasons why people use drugs. Some people use drugs because
they like the rush it gives them or because they are thrill-seekers. Others
may try a drug out of curiosity or because their friends do it. However,
many people use drugs in order to cope with unpleasant emotions and the
difficulties of life. In fact, the National
Alliance on Mental Illness estimates that around 50% of drug abusers
also suffer from a mental illness such as depression, anxiety, bipolar
disorder, or schizophrenia.
People who are suffering emotionally use drugs—not in order to get
high—but to feel normal. Drug use can be a seemingly attractive and
easy escape from all kinds of problems. Speed might be used to fight feelings
of inferiority, sleeping pills to deal with panic attacks, or painkillers
to numb depression. However while drug use might make a person feel better
in the short-term, this attempt to self-medicate ultimately backfires. Instead
of treating the underlying problem, drug use simply masks the symptoms. Take
the drug away and the problem is still there, whether it be low self-esteem,
stress, or an unhappy family life. Furthermore, prolonged drug use eventually
brings its own host of problems, including major disruptions to normal, daily
functioning. Unfortunately, the psychological, physical, and social consequences
of drug abuse and dependence are often worse than the original problem the
user was trying to cope with or avoid.
As a psychotherapist in private practice in the bay area I have had an opportunity to interact and work with ADAPT Programs on several occasions.
