Mixing these substances can prove lethal, or cause strokes and other serious health issues. Studies note that some combinations can lead to additional drug use, including heroin use that follows sedative use.

However, CBD treatment has been found to reduce motivation to self-administer methamphetamine on a progressive ratio schedule and to reduce methamphetamine-primed reinstatement of drug-seeking (Hay et al., 2018). The additive effects of cannabinoid and psychostimulant polydrug use appear to be dependent on both the amount of drug consumed and the age range during use. For example, acute THC weakens psychomotor sensitization, but repeated THC administration promotes tolerance to the acute effects, increasing amphetamine-induced stereotypy and locomotor activity (Gorriti et al., 1999; Cortright et al., 2011). Additionally, adolescent THC exposure accelerates acquisition of cocaine self-administration and increases intake of low doses of cocaine (Friedman et al., 2019), indicating long-lasting changes in reward circuitry following adolescent THC use, similar to alcohol. Psychostimulants are the second-most widely used class of drugs, with 18 million current cocaine users and 29 million current prescription stimulant users worldwide (United Nations Office on Drugs and Crime, 2019).
- While the reasons for this increasing overlap in substances that are less frequently consumed is not totally clear, some of it may relate to the drug use trajectories where substances are added to one another in a progression.
- In addition to the physical risks of polysubstance abuse and addiction, such as overdose, abusing more than one substance at a time may worsen the symptoms of a mental disorder or contribute to the development of one.
- Finding the right addiction treatment program in a facility that cares about and supports each individual can be detrimental to a person’s recovery outcome.
- These studies further emphasize the need to consider use patterns and dose in interpretation of polydrug use effects.
- While some psychosocial therapies have been tested for certain combinations of substances, there is limited data to match specific interventions with all combinations of substances a patient might be misusing.
Although alcohol pretreatment can prevent the long-term reconsolidation of preference for morphine in drug-paired contexts (Zhu et al., 2020), adolescent alcohol exposure enhances the development of a morphine CPP (Molet et al., 2013). This finding indicates that the long-term effects of adolescent alcohol exposure are generalizable to multiple drug classes. Interestingly, co-administration of morphine and THC prevents the development of the analgesic tolerance that normally accompanies long-term exposure to either drug alone (Cichewicz and McCarthy, 2003; Cox et al., 2007; Smith et al., 2007). In addition, the analgesic effects of THC and oxycodone co-administration are additive to oxycodone alone (Nguyen et al., 2019).
The Role of Primary Care and Integrated Behavioral Health in Polysubstance Use
Within the US, over 17 million people aged 12 and above are estimated to initiate drug use annually. Rates of opioid use, in particular, are continuing to climb, with 53 million past-year opioid users worldwide and ∼11 million people in the US reporting opioid misuse within what happens if you drink on vivitrol the past year (United Nations Office on Drugs and Crime, 2019). This is especially alarming, as the number of deaths in the US involving opioids has increased 6-fold from 1999 to 2017, with ∼130 Americans dying from use per day (Centers for Disease Control, 2018).
What is Polysubstance Use?
However, drug-induced cognitive and physical impairments in humans, as assessed in a driving simulation, were found to be more severe after use of THC and alcohol compared to either drug alone (Downey et al., 2013). Conducting polydrug studies of combinations of THC or CBD with other drug classes is therefore necessary to understand the differential effects resulting from these drugs. Priority areas where addressing polysubstance use is particularly urgent may include those combinations that are shown to have negative effects and population impacts. One specific combination for research is to understand the mechanisms of specific and apparently deadly combinations of opioids with alcohol, benzodiazepines, and other sedating agents, and some work to address these interactions is underway [95].
Physical Health Effects
Preclinical studies demonstrated that cocaine enhances DA levels primarily through inhibition of the DA transporter, whereas amphetamine-like stimulants both inhibit the transporter and also directly increase vesicular release [70]. For example, cocaine increases inhibitory GABA transmission from the prefrontal cortex to VTA-GABA neurons, an effect that would disinhibit VTA-DA neurons through a mechanism that is distinct from that mediated by opioid receptors [71]. In addition to its primary effect to increase terminal DA release, amphetamine inhibits monoamine oxidase and enhances tyrosine hydroxylase, which would have the net effect of increasing DA extracellular levels, also in ways that are distinct from opioid mechanism [72]. Opioids are distinct from other rewarding substances through their actions at specific opioid receptors.
Cognitive behavioral therapy
Mixing alcohol with stimulants is erroneously thought to fight the drowsiness-inducing effects of alcohol. However, the negative effects of these drugs are hidden, so individuals https://sober-house.org/ will not observe and take charge.
