Understanding Addiction

Learn about drug addiction and substance abuse

Substance abuse, or drug abuse, is defined as an overindulgence in, excessive use of, or the development of a dependence on addictive substances. When drugs are taken in excess, they cause a direct activation of the brain’s reward system, which is responsible for the production of memories and the reinforcement of behaviors. The ingestion of drugs in large quantities produces such an intense activation of the reward system that it overpowers one’s ability to focus on the normal aspects of everyday life, and instead they become overly consumed by the desire to use their drug of choice.

Some people may find it difficult to understand why a person would subject themselves to the dangers that drug intoxication can cause. They may feel that a person should “just stop” using and be done with it. But it is not that simple. Substance abuse and dependence is an illness that stems from complications in the chemical makeup of an individual’s brain. Drug use changes the brain, thus inhibiting the user’s ability to immediately stop the behavior entirely without help.

There are a wide variety of drugs that are used by a vast amount of the world’s population. Depending on the type of drug that one uses, the resulting effects will vary. The most commonly recognized types of drugs that people are known to abuse include the following:

Marijuana (also commonly referred to as “weed” or “pot”) is the most predominantly abused drug in the United States. For some people, using marijuana causes them to experience feelings of euphoria and intense relaxation. It can also impair memory, which can be beneficial to people who are suffering from recurrent unwanted thoughts. Marijuana has also been known to distort one’s reality, which is enticing to some individuals who enjoy escaping from the stresses of their own reality.

Narcotics and opiates can include a variety of different substances, such as heroin, prescription painkillers, and opium. These types of substances can be swallowed, smoked, snorted, or injected. The use of these drugs causes the user to experience feelings of euphoria, the numbing of any pain, an increased sense of self-confidence, and ultimate relaxation.

Stimulants can include methamphetamine (meth), amphetamine (uppers, such as Adderall), and cocaine. When using these substances, people are provided with a sense of increased energy, mental acuity, and euphoria. These substances can be taken through the act of snorting, injecting intravenously, smoking, or swallowing.

Hallucinogens and dissociative drugs, which may also be referred to as psychedelics, include substances such as PCP, LSD, ecstasy, and ketamine, among others. When people use these substances, they experience changes in their sensory perceptions and thought patterns. These substances can be ingested by swallowing, smoking, or chewing.

Inhalants can involve chemical substances such as gasoline or glue, aerosols such as spray paint, gasses like propane, nitrous oxide, and nitrates. These chemicals cause an individual to become intoxicated when they are sniffed or inhaled. The process of inhaling these substances is commonly known as “huffing.”

Central nervous system (CNS) depressants and downers refer to drugs that work towards slowing down a person’s central nervous system. These types of drugs can cause the user to feel extreme relaxation and sedation. Examples of these types of downers can include various tranquilizers, barbiturates, GHB, Rohypnol, and benzodiazepines.

Statistics

Drug addiction statistics

In 2012, it was estimated that 23.9 million Americans 12 years of age and older had used an illicit drug or abused some type of psychotherapeutic medication (such as a pain reliever, stimulant, or tranquilizer). This equates to 9.2% of the population, and these numbers continue to grow.

Seemingly the most dangerous way in which a person can use drugs is by injecting it intravenously. It has been reported that in 120 countries worldwide, there has been an increase in the amount of HIV/AIDS infections transmitted through the use of shared needles.

Causes & Risk Factors

Causes and risk factors for drug addiction

There is not one specific cause or factor that can be attributed to a person’s risk level for developing an addiction to substances. The causes that lie in the development of an addiction vary from person to person and include the influence of multiple factors, such as:

Genetic: Combined with outside environmental influences, inherited genes are responsible for approximately half of one’s vulnerability for developing a drug addiction. Addiction tends to run in families; people who have a first-degree relative (such as a biological parent or sibling) that has struggled with addiction are more likely to develop an addiction themselves.

Physical: The chemicals that drugs are composed of affect the brain’s communication system and cause a disturbance in the way that nerve cells normally send, receive, and process information. The longer that people abuse substances, the more likely it is that the drugs will cause long-lasting damage to the composition of this communication system, reducing its natural flow and leading to the development of a physical dependence on the substance.

Environmental: Certain environmental factors can play a role in the development of an addiction to drugs. People who have a lot of stress in their lives may find that using drugs provides a sense of relief from the chaos around them. People who have been physically and/or sexually abused may also be at risk for developing a dependence on substances. Living in an environment where one is exposed to violence, where drugs are readily available, and where one is surrounded by peers who also use substances can all have an impact on a person’s susceptibility to developing a drug addiction.

Risk Factors:

The more risk factors that a person is subject to, the more likely they are to develop an addiction to drugs. The following are some examples of risk factors that can be attributed to the onset of substance abuse and subsequent addiction:

  • Poor self-control/impulse control
  • Lack of parental involvement
  • Poor socioeconomic status
  • History of aggressive behaviors
  • Exposure to violence
  • Exposure to some form of trauma
  • Poor life skills
  • Peer pressure
  • A person’s accessibility to the drug

  • Depressive disorders
  • Anxiety disorders
  • Bipolar disorder
  • Schizophrenia
  • Polysubstance abuse

I had a great experience at this facility. I have been to one other facility in the past and I can really tell the difference. The process starts with a FREE assessment and it was done relatively quickly. The staff were empathetic and seemed to really care about helping me. Once I got on the unit I met with other staff who were equally helpful. I got to meet with my doctor and therapist while here and my stay was actually pretty comfortable. I was especially pleased with the beginning stages as I was desperate for help and I got it quickly. The hospital is open 24/7 and an assessment can be done without an appointment.
