Drug Addiction: Why Does It Occur and What Can We Do About It?


People from all phases of life can experience issues with drug usage regardless of age, race, or the reason for which they started using the drug. Drug addiction does not necessarily have to be illegal drugs. Even prescription drugs like painkillers, sleeping pills, and tranquilizers can lead to drug abuse and addiction. One of the most common and unfortunate addictions that affect millions of people a day is drug addiction. Drugs affect different people differently. A person takes a drug yet never gets addicted, while another person gets hooked to the drug. Drug abuse and addiction are now clubbed together as a substance or drug use disorder.

Drug dependence is on a high and is seen as the new age epidemic. Around eight percent of people in America experience this at some point of time in their lives. Addiction affects just not the body, but it has a great impact on mental health and soundness of mind. It is considered to be one of the most severe health issues faced around the world and is termed a chronic disease.

What Is Drug Addiction?

Drug addiction is characterized by an uncontrollable desire to take the drug (craving), along with compulsive drug seeking that persists despite devastating consequences. It refers to a condition in which you cannot resist the urge to use them no matter how much harm the drugs may cause.

Addiction has far-reaching health and socioeconomic consequences. Drug abuse and addiction increase the individual's risk for a variety of other psychiatric and physical illnesses.

Certain people are typically more vulnerable than others to develop drug dependence, and this depends on the interplay between genetic makeup, the age of exposure to drugs, and other environmental influences.

What Are the Signs of Drug Addiction?

  • The person keeps taking the drug even after it is of no use for the health condition.

  • The person keeps taking the drug to experience the effects of the drug.

  • The person is not able to stop the drug even if they want to.

  • The individual gets a strange feeling or shaky or depressed feeling when the drug wears off. In severe cases, the person can even experience fever or have seizures.

  • The person keeps thinking about the drug, about when to take it, or how to get more.

  • The individual would have lost interest in things once they loved to do.

  • Feeling sad or low always.

  • Having trouble doing the routine and regular activities.

  • Trouble getting along with people.

  • Excessive sleeping or not being able to sleep or sleeping at strange hours.

  • Eating a lot more or a lot less than before.

  • Tremors or shakes.

  • Frequent nosebleeds.

  • Slurred speech.

The symptoms differ based on the type of drug. Some of the signs and symptoms of drug addiction caused due to taking illegal drugs like marijuana, cannabis, and hashish include:

  • A sense of feeling high.

  • Increased blood pressure.

  • Raised heart rate.

  • Dry mouth.

  • Redness in eyes.

  • Difficulty concentrating.

  • An increased sense of visual, auditory, and taste perception.

  • Hallucinations.

Drug Dependence, a Disorder of the Brain Circuit:

A number of brain areas are included in the genesis of addiction. But, the nucleus accumbens is the most studied target. This brain structure is basically involved in the reward and motivation pathway.

Drug dependence is not a moral weakness but a disorder of the brain circuitry. Drug addiction is a complex illness.

People want to take more and more drugs as they feel intoxicated after using the drugs. And over time, the brain is changed by the drugs. The brain becomes desensitized to the drug wanting more of the drug to produce the same effect.

How Is Drug Addiction Treated?

  • Effective treatment programs typically involve multiple components, each directed to a particular aspect of the illness and its consequences.

  • Individualized treatments focus on maintaining a drug-free lifestyle and achieving productive functioning. Clients require continued long-term care to achieve abstinence from drug usage.

  • A few evidence-based interventions: cognitive behavioral therapy (CBT) and motivational enhancement therapy (MET), remain the cornerstones of addiction treatment.

  • In addition to these interventions, some approved pharmacological interventions include Methadone maintenance therapy and Buprenorphine maintenance treatment for opioid dependence, Naltrexone drug therapy after medical detoxification, and nicotine replacement therapy (NRT) for tobacco cessation.

  • Bupropion and Varenicline are the FDA-approved agents for smoking cessation.

  • The agents that have been approved for alcohol dependence include Naltrexone, Acamprosate, and Disulfiram. All these agents should be administered under the guidance of a psychiatrist.

  • The behavioral interventions include CBT, contingency management interventions, community reinforcement approaches, the matrix model, and the 12 step facilitation therapy.

  • A holistic approach would also entail family-based interventions. Multidimensional family therapy involves working on decision-making, negotiation, and problem-solving skills.

Can Drug Addiction Be Prevented From Relapsing?

There are high possibilities for you to fall back into the same pattern of addiction. And once you start using it again, then it is very hard to get control over it. Here are a few steps you can follow to keep yourself from getting addicted again:

  • Strictly follow the treatment plan even if you feel you have recovered from it. You can visit your therapist or counselor regularly to stay drug-free.

  • Avoid going to areas where you purchase these drugs.

  • Indulge yourself in recreational activities so that you do not get to remember the drugs.

  • Get immediate help if you start over the drug again.


Drug abuse and drug addiction are preventable. Confronting your addiction can be the most challenging thing you have ever done, but you do not have to do it alone. You can involve your families, friends, or your loved ones to help you from staying away from drugs. If you do not feel good asking your family or friends, there are several self-help groups to help you out from overcoming the toxic cycle of drug addiction.
