It has also been shown that depression and polysubstance dependence are often both present at the same time. If a person is genetically predisposed to be depressed then they are at a higher risk of having polysubstance dependence.Possibly the most widely accepted cause of addictions is the self-medication hypothesis, that views substance addiction as a form of coping with stress through negative reinforcement, by temporarily alleviating awareness of or concerns over the stressor. People who use substances learn that the effects of each type of substance works to relieve or better painful states. They use substances as a form of self-medication to deal with difficulties of self-esteem, relationships, and self-care. Individuals with substance use disorders often are overwhelmed with emotions and painful situations and turn to substances as a coping method. Sociocultural
The sociocultural causes are areas in a persons life that might have influenced their decision to start and continue using multiple substances. Sociocultural causes can be divided into social causes and cultural causes. Social Causes: Some studies have shown that adolescents have one of the highest rates of polysubstance dependence. According to one study this population, ages 12–25, represents about half of the nations population that uses illicit substances. Of these individuals, half of them have started using substances by the end of 12th grade. This could be attributed to social expectations of peers, peer pressure to fit it, or a way of numbing their emotions.
Diagnosis

In addition they must show a minimum of three of the following symptoms listed below, all within the past twelve months. There is a distinct difference between a person having three separate dependence issues and having Polysubstance dependence the main difference is polysubstance dependence means that they are not specifically addicted to one particular substance. This is often confused with multiple specific dependences present at the same time. To elaborate, if a person is addicted to three separate substance such as cocaine, methamphetamines and alcohol and is dependent on all three then they would be diagnosed with three separate dependence disorders existing together (cocaine dependence, methamphetamine dependence and alcohol dependence,) not polysubstance dependence. In addition to using three different substances without a preference to one, there has to be a certain level of dysfunction in a persons life to qualify for a diagnosis of polysubstance dependence. One of the bigger challenges that often occurs when trying to diagnose is the fact that people dont always report what they are taking because they are afraid of getting into legal trouble. When coding polysubstance Dependence in a DSM-IV it would be a multiaxial diagnosis 304.80- Polysubstance Dependence", next to the classification, it is accompanied by a list of other types of Substance dependence (e.g.
