Polysubstance dependence refers to a type of substance use disorder in which an individual uses at least three different classes of substances indiscriminately and does not have a favorite substance that qualifies for dependence on its own. Although any combination of three substances can be used, studies have shown that alcohol is commonly used with another substance. This is supported by one study on polysubstance use that separated participants who used multiple substances into groups based on their preferred substance. The results of a longitudinal study on substance use led the researchers to observe that excessively using or relying on one substance increased the probability of excessively using or relying on another substance. Common combinations
The three substances were cocaine, alcohol, and heroin, which implies that those three are very popular. Other studies have found that opiates, cannabis, amphetamines, hallucinogens, inhalants and benzodiazepines are often used in combination as well. Presentation
Associated cognitive impairments
Cognition refers to what happens in the mind, such as mental functions like "perception, attention, memory, language, problem solving, reasoning, and decision making." Although many studies have looked at cognitive impairments of individuals who are dependent on one substance, there are few researchers who have tried to determine the problems with cognitive functioning that are caused by dependence on multiple substances. Therefore, what is known about the effects of polysubstance dependence on mental abilities is based on the results of a few studies. Learning ability
The effect of polysubstance dependence on learning ability is one area of interest to researchers.
Treatment must be individualized and last a sufficient amount of time to ensure the patient has kicked the addictions and to ensure the prevention of relapse. The most common forms of treatment for polysubstance dependence include: inpatient and outpatient treatment centers, counseling and behavioral treatments, and medications. It is important that treatments be carried on throughout the patients life in order to prevent relapse. It is a good idea that recovering addicts continue to attend social support groups or meet with counselors to ensure they do not relapse. Inpatient treatment center
Inpatient treatment centers are treatment centers where addicts move to the facility while they are undergoing treatment. Inpatient treatment centers offer a safe environment where patients will not be exposed to potentially harmful situations during their treatments as they would on the outside. Inpatients usually undergo the process of detoxification. Detox involves withdrawing the user (usually medically) from all substances of concern. During their stay in the treatment facility, patients often are learning to manage and identify their substance addictions and to find alternate ways to cope with whatever is the cause of their addiction. Outpatient treatments
Outpatient treatments include many of the same activities offered in an inpatient treatment facility, but the patient is not protected by the secure and safe environment of an inpatient treatment center. For this reason, they are significantly less effective. The patient usually continues to hold a job and goes to treatment nightly. Twelve-step programs
Both in-patient and out-patient treatments can offer introductions to 12-step programs.
