Drug addiction is a condition that affects millions of individuals and their families every day. The devastation that drug addiction leaves in its wake can be felt in relationships, careers and the health of the individual struggling with the disease. A dependence on illicit or prescription drugs can cause individuals to lose their families, their jobs or even their lives. Sadly, the majority of people who suffer from drug addiction will never seek the help they need. Instead of contacting a drug rehab facility, they remain isolated, falling deeper and deeper into the cycle of addiction. But there is hope and healing through drug rehab treatment.

There are a variety of different drug addictions currently being treated in the rehab centers of America and around the world. The ones currently ranked as the most prevalent in the United States include:


Heroin addiction — This powerful opiate remains one of the most dangerous in the world. The constant fear of overdose, long-term health problems and the risk of contracting HIV/AIDS all make heroin addiction a certified killer.


Marijuana addiction — While medical professionals debate whether or not marijuana is technically addictive, the drug continues to keep individuals from reaching their full potential and even acts as a gateway drug to more serious substances.


Cocaine addiction — Although cocaine use is nowhere near its peak from the 1980s and 1990s, thousands of people each day enter drug rehab in an attempt to break free from the strong psychological pull of cocaine addiction.


Prescription drug addiction — Prescription painkillers are the drugs of choice for many people, both young people, and adults, around the country. Opiates, including Vicodin and OxyContin, are highly addictive and can be as dangerous as heroin if given the wrong set of circumstances.

Causes and Contributing Factors

Though there are a number of theories about what causes drug addiction, the truth is that for each individual, the answer is different. Usually, it is a combination of genetic impulses toward addiction or compulsive behaviors and environmental influences. Simple things like early access to drugs and alcohol, childhood trauma and chronic psychological conditions increase the likelihood of developing addiction to drugs and alcohol. Determining what caused or contributed to the addiction through rehab helps those in recovery find answers and healing.

Some of the most common reasons people develop addiction include:
  • Genetics. A large proportion of those who receive treatment for a drug addiction report having a parent or other family member who had a similar condition.
  • Co-dependence. Found predominantly in women, co-dependence occurs when an individual becomes addicted to drugs because their significant other has the same condition.
  • Self-esteem or self-image issues. Many women and young people develop drug addiction due to concerns about their appearance. This commonly occurs with teens who have trouble fitting in at school and women who suffer from eating disorders due to a distorted view of their own self-image.
  • Physical or sexual abuse. A high number of drug addicts have a history of sexual or physical abuse. The pain and shame associated with abuse leads them to self-medicate with drugs or alcohol.
  • Mental illness. Over half of those with a drug addiction also suffer from mental illness. People with clinical depression, anxiety, bipolar disorder and borderline personality disorder are all at a high risk for addiction.4
A few other ways that drugs can affect the brain and create long-term changes include:
  • Pleasure pathway changes. Drugs trigger the brain’s reward system and create feelings of euphoria. Dopamine floods the brain and over-stimulates the system, creating a “high.” Over time, those who struggle with addiction can no longer trigger dopamine production on their own.
  • Cravings. The body and the brain enjoy the feel-good effect of drugs. Over time, the individual can come to crave the “high” associated with drug abuse.
  • Impaired brain function. Drug abuse alters the brain’s ability to experience pleasure and impairs brain functioning. The individual’s perspective and cognitive abilities can be impaired long after the drug of choice wears off.
  • Tolerance. Over time, the brain grows accustomed to the initial level of the chosen drug and requires more of it to enjoy the same experience.
  • Lowers inhibitions. Under ordinary circumstances, the brain has limitations and boundaries; when drugs are present, those boundaries lift and inhabitations disappear.
  • Long-term changes. In the same way that the brain develops a tolerance to a particular drug, there are concurrent changes in the brain caused by getting high repeatedly. The brain has to be retrained to return to its old level of cognitive function; in some cases, the changes cannot be completely reversed.5
