DXM has been available since the 1950s, though it was once removed from the market due to its potential for abuse. The drug was brought back in less palatable forms because of its usefulness as a cough suppressant. Over time, the drug has found its way into many different types of over-the-counter medications.
DXM is a synthetic derivative of morphine that inhibits the release and action of the excitatory neurotransmitter N-methyl-D-aspartate (NDMA), an action that helps to suppress the cough reflex. The drug is not controlled substance; however, the United States Drug Enforcement Administration (DEA) does list it as a drug of concern.
According to the available data from the Substance Abuse and Mental Health Services Administration (SAMHSA) and the National Institute on Drug Abuse (NIDA), the abuse of DXM typically occurs in younger individuals. Abuse may be more prevalent in young females under the age of 18 and in males between the ages of 18 and 26 years old.
It is impossible to separate the “purely physical effects” from the “purely mental effects” associated with any medicine, drug, or other substance. The effects of any substance occur as a result of an interaction between the physiology that is associated with the drug’s breakdown and assimilation, and the cognitive and emotional effects that interact with the physical process of using the substance. When substances are combined, these interactions become even more complex. The notion that ingesting any substance can produce “purely physical effects” or “purely mental effects” is a misconception, as these categories do not exist in the real world. All behaviors, reactions, and so-called physical states represent a combination of physical processes and cognitive or emotional mechanisms even if individuals are not overtly aware of their cognitive or emotional ramifications.
The potential interaction between DXM and alcohol, of course, depends on the amounts of the drugs taken. As one takes higher amounts of the DXM, even a very small amount of alcohol could provide a significant interaction. Combining DXM with alcohol can also result in a number of other potential effects that include:
NIDA lists a number of potential long-term problems associated with chronic abuse of DXM. These potential problems will only be exacerbated if DXM is chronically abused with alcohol. These serious potential long-term effects include:
None of the above effects are either “purely physical” or “purely mental.” For instance, liver damage will often result in cognitive issues, such as confusion, issues with memory, and even delirium due to metabolic issues. Neurological damage can result in issues with simple or complex movements that can lead to accidents and other potential injuries.
Most of the data supplied by the DEA, NIDA, and SAMHSA suggest that even though chronic use of DXM is associated with the development of tolerance to the drug, physical dependence on DXM most likely does not occur. Nonetheless, individuals who chronically misuse or abuse any drug may develop a number of emotional attachments to using the drug to help them cope with stress, and when they discontinue the drug, this may result in a number of psychological and/or emotional stressors. Thus, chronic use of these drugs in combination can potentially result in very complicated issues associated with the development of a polysubstance use disorder. Because even moderate use of alcohol for prolonged periods of time can result in a severe alcohol withdrawal syndrome that can be potentially fatal due to the development of seizures, anyone who has repeatedly used alcohol and DXM together should consult with a licensed medical professional before they discontinue use of these drugs.
Using DXM and alcohol in combination represents a dangerous and potentially fatal practice. Because both drugs are central nervous system depressants, using them in combination enhances both their effects and can lead to numerous potentially serious conditions. The potential dangers of using these drugs in combination are significantly exacerbated when one uses DXM or alcohol at higher doses. Individuals who regularly abuse these drugs should seek professional help.
