What is substance abuse/addiction?
Based on the different theories surrounding the causes of addiction, the definition varies across schools.
Addiction: A primary, chronic, and neurobiological disease with genetic, psychosocial, and environmental factors influencing its development and manifestations. It is characterized by behaviours that include one or more of the following: impaired control over medication use, compulsive use, continued use despite harm, and craving.
What is the difference between Substance Abuse and Addiction?
The Diagnostic and Statistical Manual of Mental Disorders IV-R describes abusers as those who abuse substances despite recurrent social, interpersonal, and legal problems as a result of using. Harmful use implies substance use that causes either physical or mental damage.
Abuse and addiction are not the same. Abuse always comes before addiction, which is chronic and treatable. Abuse starts when there is a conscious decision to abuse substances. Used too often, the individual eventually craves the substance because physical changes in the brain haven taken place. Substances interfere with the brain’s natural processes by making both temporary and structural changes in brain cells. Mood, memory, thinking, and even motor skills such as walking may be affected. When this happens, drug abuse turns into addiction. People who are addicted have a compulsive craving and cannot quit by themselves.

What causes substance abuse/addiction?
While some researchers would say that there are a specific number of personality traits that precede the development of substance abuse one can not predict with certainty that any personality traits predispose a person to abusing substances. Therefore, we can not determine with confidence that, based on someone’s personality alone, they will become a substance abuser.
The medical model claims that addictions are a disease. This model states that addiction is an inherited disease, and an addicted individual is permanently ill, at a genetic level. The medical model also believes that like other medical diseases the person will remain ill even after years of sobriety.
The Dual Diagnosis philosophy dictates that addiction is a dual problem consisting of both physical and mental dependency on chemicals, combined with a pre-existing mental disorder and that the mental disorder needs to be treated first as the primary cause of the addiction. This philosophy supports the idea that chemical dependency leads to chemical imbalances in the neurological system, which would be then a substance induced imbalance.
What treatments are available?
1.Cognitive Model of Addiction (CT)– this theory is based on Aaron T. Beck’s work that examined thoughts as the originating factor of any behaviour. An individual’s behaviour and affect are determined by his or her view of the world and the way they structure their world. Beck’s work also explored what he called a “schemata”- a stable, mental representation of experiences that are involved in the evaluation of information. Basically, thoughts are interpreted based on experiences and activating emotions when new situations and events arise.
Abnormal or dysfunctional thinking occurs when systematic distortions are applied to the new incoming situations or events affecting motivations, actions, and feelings. CT is utilized to change these cognitive distortions by assisting the client to change one’s actions, motivations, and feelings by assisting the client in challenging their own dysfunctional cognitive processes.
There are many reasons people use and abuse substances; they range from pleasure, creativity, experimentation, and relief from sadness, anxiety or even boredom. It is the underlying belief in any reason for substance use that shape the physiological sensations linked to the cravings and usage, and eventually addiction.
These addicted behaviours are shaped from core beliefs that have to do with personal survival, autonomy, and freedom. An addict’s beliefs, in all three of these areas are dysfunctional. The dysfunctional thought patterns seem to take over and as the person becomes addicted, the drug appears to take control of the individual. The obstacle in addiction is eliminating the person’s dysfunctional beliefs that they hold about the substance. These dysfunctional beliefs can range from fear of side affects to the belief that they cannot function without the substance. Changing the maladaptive beliefs, thought patterns, and schemas are at the core of the CT approach for substance abuse and addiction. These beliefs must be changed in order for long-term behavioural change and sobriety.
In CT patients are taught to face the source that is leading to their emotional distress and to change the beliefs that substances can assist in the mending of these or any other problems. This is done by reducing the intensity and frequency of the urges by exploring the underlying beliefs and to teach the patient techniques for managing and controlling their urges. In all areas the individual’s faulty beliefs about people, events, and their views on drug and alcohol use need to be fully examined.
2.Acceptance and Commitment Therapy (ACT)
ACT, a form of CBT, uses a wide range of experiential exercises to examine the power of destructive cognitive, emotive, and behavioural processes that have contributed to and maintain substance abuse problems. It helps clients to fundamentally change their relationship with painful thoughts and feelings, to develop a clearer sense of self, to live in the present, and to take action, guided by personal values, and to create a rich and meaningful life without the use of substances.
ACT takes the view that most psychological suffering is caused by ‘experiential avoidance’, i.e. by attempting to avoid unwanted private experiences, such as unpleasant thoughts, feelings, urges & memories. The individuals efforts at experiential avoidance might work in the short term, but in the long term they often fail, and in the process, they often create significant psychological suffering. In individuals with substance abuse disorders or any serious addiction: in the short term the substance of choice makes a person feel good and helps rid of unpleasant thoughts and feelings – but in the long term, it destroys their health and vitality.
In ACT, clients develop “mindfulness skills” which enable them to fundamentally change their relationship with painful thoughts and feelings and the connection these thoughts and feelings have with substances. When clients practice these skills in everyday life, painful feelings and unhelpful thoughts have much less impact and influence over them. Therefore, instead of wasting their time in a battle with their inner experiences, they can invest their energy on taking action to change their life for the better – guided by their deepest values and absent of drugs and alcohol.
3.Emotion Regulation and Mindfulness
Growing literature is supporting the importance of emotional regulation in the treatment of substance abuse. Research has mainly been done on nicotine cessation however, since nicotine and other psychoactive substances, such as cocaine, activate similar psychopharmacological pathways, an emotion regulation application may be applicable. This model focuses on negative reinforcement as the primary driving force for addiction and patients are encouraged to identify and recognize their negative and emotional states and prevent the maladaptive, impulsive, and compulsive responses that they developed to deal with them. In the cases of addiction, these responses would be abusing substances. Like CBT this approach involves the thoughts involved in maladaptive and dysfunctional emotional states but the focus here is the reaction to those states. Therefore, this could be used in conjunction with CBT if found affective.
