Combining drugs (stimulants, depressants, hallucinogens, etc.) can have serious health consequences. If you are struggling with substance or polysubstance use, you’re not alone. The first step to seeking help and making change is being honest with yourself about your behavior. Polysubstance use can impact your mind, body, relationships, and other aspects of your life. Though recovery can be challenging, it is possible with social and professional support.
Prelimbic cortex is a common brain area activated during cue-induced reinstatement of cocaine and heroin seeking in a polydrug self-administration rat model. Repeated exposure of the posterior ventral tegmental area to nicotine increases the sensitivity of local dopamine neurons to the stimulating effects of ethanol. Unlike psychostimulants, nicotine enhances DA release via activation of nicotinic acetylcholine receptors within the VTA. NACh receptors are non-selective cation channels, with permeability to Na+, K+, and Ca2+, and their activation leads to depolarization and enhanced neurotransmitter release .
Ways How to Help an Alcoholic
Recovery from alcohol and drug addiction is possible, for you or a loved one. Cognitive Behavioral Therapy gives people the power to examine the underlying causes of their addictive behaviors. As each trigger is identified with the help of a counselor, patients learn over time to not just should you go back to rehab after a relapse avoid these triggers but to confront them in a more positive, less socially and personally destructive way. A role for conditioned ventral tegmental glutamate release in cocaine seeking. Ethanol facilitates glutamatergic transmission to dopamine neurons in the ventral tegmental area.
Recent evidence shows an increasing rate of methamphetamine use among adults in the U.S. admitted to treatment programs for heroin addiction . The implication is that overlap of opioids with other substances is common but can vary across time, both within an individual and within populations of users. This is the first study in Jamaica and the Caribbean that demonstrates the prevalence of concurrent polysubstance use, combinations of substances used, and associations with sociodemographic factors. This research found that approximately 1 in every 5 Jamaicans aged 12–65 years used two or more drugs in their lifetime. This is comparable to our Latin American neighbours that undertook a similar survey and reported that 21% of participants combined at least two substances .
Induce sedation, and stimulants like caffeine and methamphetamine can lift low moods. In addition, since each chemical has a different effect, there is a propensity to combine them and produce multiple effects simultaneously. As America continues to battle the onslaught of addiction to opioids and other substances, it’s critical that friends, family, colleagues, and anyone touched by someone else’s addiction, understand and speak out about the fact that this is a disease. Relapse Prevention Therapy helps users identify triggers that might cause them to use substances to get high, and teaches strategies and techniques for learning to cope with triggers and ways to avoid them.
If your health care provider prescribes a drug with the potential for addiction, use care when taking the drug and follow instructions. Difficult family situations or lack of a bond with your parents or siblings may increase the risk of addiction, as can a lack of parental supervision. Use of hallucinogens can produce different signs and symptoms, depending on the drug.
If you start using these substances together, a new metabolite is formed, as mentioned above. This metabolite, cocaethylene, can also cause your heart rate and blood pressure to increase more than if you were using these substances in isolation. The metabolite produced by polysubstance abuse here also increases toxicity to the liver, heart, and other major organs. If you have a co-occurring mental health condition along with polysubstance use disorder, this can become inflamed by the use of multiple drugs. The former definition of polysubstance abuse was a substance dependence disorder where the person regularly uses three or more substances or groups of substances. For instance, taking more than one depressant drug can increase the risk of overdose or death.
Because NAc output is heavily regulated via local GABAergic microcircuitry, increased activity of iMSNs would likely dampen overall NAc output. This is supported by the upregulation of Ca2+-permeable AMPA receptors in the NAc that are capable of conducting Ca2+ in the absence of NMDA receptor activation (Ponzoni et al., 2019). Long-term nicotine use also produces a persistent increase in mPFC pyramidal cell and NAc MSN dendritic branching (Brown and Kolb, 2001; Hamilton and Kolb, 2005; Ehlinger et al., 2016), similar to psychostimulants.

You suspect potential drug or alcohol use but you feel helpless and don’t know how to approach the subject. In this article, we’ll give you some important information about what is called polysubstance dependence, signs to look for, and how you can help. This may also be referred to as combined drug intoxication or multiple drug intake.
Typically, the term “gateway drug theory” refers to use of tobacco and alcohol preceding marijuana, followed by “harder drugs” like cocaine or opioids, and most who misuse opioids have already used legal drugs and marijuana . An important consideration of the theory is that the gateway drug is often used during adolescence. This is a window of brain development during which perturbations such as drug exposure can produce unique and enduring effects. A neurobiological basis for polysubstance use is that combining drugs that converge on a common circuit at different points can produce additive or synergistic rewarding effects. Synergistic pharmacological interactions occur with drugs that have different mechanisms but a common end consequence, such as increasing dopamine release in the nucleus accumbens .
Toxic effects of low alcohol and nicotine combinations in SH-SY5Y cells are apoptotically mediated. Effects of nicotine on the nucleus accumbens and similarity to those of addictive drugs. Intravenous cocaine, morphine, and amphetamine preferentially increase extracellular dopamine in the “shell” as compared with the “core” of the rat nucleus accumbens. Alcohol consumption increases basal extracellular glutamate in the nucleus accumbens core of Sprague–Dawley rats without increasing spontaneous glutamate release.
The role of addiction-medicine specialists in the global fight against addiction
Pyramidal cells in layers II/III send local projections within cortex, while those in layers V-VI send projections throughout the C-BG-T, including to the striatum, midbrain, amygdala, hippocampus, and thalamus (Gabbott et al., 2005; Santana and Artigas, 2017). Pyramidal cells can be further subdivided based on physiology and connectivity (Morishima and Kawaguchi, 2006; Brown and Hestrin, 2009; Reiner et al., 2010; Shepherd, 2013; Kim E. J. et al., 2015). Finally, the PFC contains multiple populations of interneurons that heavily regulate cortical output via projections to both pyramidal neurons and interneurons (van Versendaal and Levelt, 2016; Batista-Brito et al., 2017). Polysubstance abuse may also refer to the non-medical use of prescription medications. Alternatively, they are using different prescriptions without knowing that the combinations of drugs hazardous. Lastly, patients sometimes are unaware they should not mix their medications with alcohol.
What are 2 examples of drugs?
- methamphetamines (e.g. MDMA) and other stimulants such as cocaine.
- new psychoactive substances – synthetic drugs.
- opioids, including heroin.
- the non-medical use of prescription drugs.
Effects of ethanol exposure and withdrawal on dendritic morphology and spine density in the nucleus accumbens core and shell. Effect of low doses of Δ9-tetrahydrocannabinol and cannabidiol on the extinction of cocaine-induced and amphetamine-induced conditioned place preference learning in rats. Chemogenetic modulation of accumbens direct or indirect pathways bidirectionally alters reinstatement of heroin-seeking in high-but not low-risk rats. Juvenile ethanol exposure increases rewarding properties of cocaine and morphine in adult DBA/2J mice. Effects of daily delta-9-tetrahydrocannabinol treatment on heroin self-administration in rhesus monkeys.
Preventing drug misuse in children and teenagers
Multiple substance use disorders can also impair judgment, vision, and coordination, increasing the risk of injury. Studies reveal that 35% to 50% of people in emergency rooms with a traumatic brain injury struggle with alcohol or drug abuse. In contrast, THC reduces the motivation to self-administer cocaine in rodents (Panlilio et al., 2007). Although this suggests a differential regulation of cocaine’s effects in humans and rodents, further work is necessary to ensure that animal models of increased addiction severity cannot, in fact, be developed. Notably, however, neither cocaine and cannabis nor cocaine and alcohol co-administration in humans produces subjective effects that are different from cocaine, cannabis, or alcohol alone (Foltin et al., 1993).
- Polysubstance abuse can influence a tendency to exaggerate symptoms or outright lie about them to have a valid reason to visit pharmacies and doctors regularly to get a refill or try new drugs.
- What starts out as simply partying with friends can turn into a full-blown dependence or addiction quicker than many realize.
- Some studies concluded illicit substance use to be higher among rural individuals , while others indicate a greater preponderance in urban areas .
- In addition, pre-exposure to alcohol or simultaneous access to both alcohol and nicotine decreases nicotine self-administration in rodent studies (Lê et al., 2010, 2014).
Combining these models with behavioral economic paradigms could clarify how the relative value of drugs and alternative reinforcers changes with polydrug use to improve treatment efficacy. Addiction is a complex disease with multiple, highly variable factors contributing to the initiation and maintenance of drug use, as well as relapse. Given the widespread prevalence of polydrug use among drug users, it is critical that we incorporate this variablility into human studies and animal models. This will help to determine if polysubstance use exacerbates SUD severity, if increased SUD severity drives polysubstance use, or if there is a bidirectional relationship between the two. As with psychostimulants and opioids, administration of nicotine with THC augments the effects of either drug alone when measured in tests of locomotion, analgesia, and hypothermia (Valjent et al., 2002). In addition, THC and nicotine co-administration exacerbates the somatic symptoms of THC withdrawal (Valjent et al., 2002).
Inspire Malibu isJoint Commission accreditedand has been designated a Higher Level of Care from the Department of Health Care Services. 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 . 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 . 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 . Opioids are distinct from other rewarding substances through their actions at specific opioid receptors.
People who are addicted to drugs are more likely to drive or do other dangerous activities while under the influence. MDMA ― also known as molly or ecstasy ― can interfere with the body’s ability to regulate temperature. A severe spike in body temperature can result in liver, kidney or heart failure and death.

Patterns of opioid consumption and progression vary according to sex and gender and detailed analysis of these patterns for polysubstance use are needed as well to optimize individualized strategies for prevention and treatment. Additionally, sex differences can be used as a tool to elucidate the neurobiological mechanisms underlying polysubstance abuse. In addition to acute actions described above, all drugs of abuse produce long-term plasticity that contributes to compulsive behaviors that characterize substance use disorder. They do so through multiple mechanisms, and a description of this is beyond the scope of this Perspective. However, a shared mechanism through which most drugs of abuse induce enduring neuroadaptations is by increasing the AMPAR/NMDAR ratio, resulting in enhanced excitatory transmission onto VTA-DA neurons . The mechanisms by which individual drug classes produce their effects and whether these are specific to individual classes is a topic of future investigation.
What are the Most Commonly Abused Prescription Drugs?
The affective and neural correlates of heroin versus cocaine use in addiction are influenced by environmental setting but in opposite directions. Voluntary induction and maintenance of alcohol dependence in rats using alcohol vapor self-administration. Dopamine neurons projecting to medial shell of the nucleus accumbens drive heroin reinforcement. Δ9-Tetrahydrocannabinol produces naloxone-blockable enhancement of presynaptic basal dopamine efflux in nucleus accumbens of conscious, freely-moving rats as measured by intracerebral microdialysis.
With polysubstance use, a person takes two or more drugs simultaneously or within a short period of each other. Combined drug intoxication can occur with alcohol, drugs, and prescription medications. Family therapy is an essential component of substance abuse treatment because sustained recovery occasionally necessitates the participation of all family members. Family therapy offers relatives the chance to learn everything there is to know about the disorder and how they can be of assistance. As a result, it equips families with the necessary tools to build a better functioning home environment capable of navigating recovery for lasting change. While some drugs, like inhalants, damage nerve cells in the brain or peripheral nervous system, others raise the possibility of acquiring infections like HIV and hepatitis C, which can be acquired via sharing injectables.
What are drug packages called?
Blister packs are pre-formed plastic/paper/foil packaging used for formed solid drugs. The primary component of a blister pack is a cavity or pocket made from a thermoformed plastic. This usually has a backing of paperboard or a lidding seal of aluminum foil or plastic film.
Additionally, those living in rural areas were 1.508 times more likely than participants living in urban areas to report past month polysubstance use. As it relates to occupational status, skilled workers were 4.328 times more likely and unskilled workers were 7.146 times more likely to alcoholism & hypoglycemia report past month polysubstance use. This model indicated no significant associations between marital status and religious status and past month polysubstance use. There was no other statistical significance noted between other age groups and past month concurrent polysubstance use.
