Many people use alcohol and marijuana simultaneously, but the combined effects can elevate THC levels, intensify impairment, and lead to alcohol poisoning. While people often mix these substances to enhance effects or counter side effects, it poses risks and can be unsafe.
Alcohol and Marijuana Co-Use
Alcohol and marijuana are the two most abused addictive substances in the United States. The most current data from SAMHSA (Substance Abuse and Mental Health Services Administration) indicate that:
- 221 million U.S. adults consumed alcohol in 2022. Among these, over 29 million developed alcohol use disorder (alcohol addiction) in the same year.
- 62 million U.S. adults consumed marijuana in 2022. Among these, 19 million developed marijuana use disorder (marijuana addiction) in the same year.
Co-using alcohol and marijuana is a common practice, but it comes with its own set of effects and risks. Understanding how these substances interact is beneficial for those who engage in this behavior. The combined impact of marijuana and alcohol on the CNS (central nervous system) and cognitive functions can lead to notable alterations in perception and behavior.
Effects of Mixing Marijuana and Alcohol
Mixing alcohol and marijuana can accelerate and intensify their effects. Both substances impact the CNS. Marijuana affects memory, thinking, pleasure, and sensory perception, while alcohol, as a depressant, heavily impairs motor skills, judgment, cognition, and memory.
THC (tetrahydrocannabinol), a key compound of marijuana, and alcohol are psychoactive, acting on cannabinoid receptors in the brain and triggering cognitive effects and impairments. When consumed together, alcohol enhances THC absorption, leading to a more pronounced high, but it also amplifies the associated lows, making impaired judgment more conspicuous, for instance.
The risks and side effects of mixing weed and alcohol include:
- Enhanced effects of THC: Combining alcohol with any substance extends its presence in the system, as the liver prioritizes alcohol metabolism. This can intensify the effects of THC.
- Overdose potential: Combining drugs with alcohol increases the risk of overdosing on either substance. While THC overdose effects can be harmful, the dangers associated with alcohol overdose are more severe, including the potential for alcohol poisoning and fatal outcomes.
- Decreased judgment: Both alcohol and marijuana products impair rational thinking. Their synergistic effects when combined can amplify impulsivity, poor judgment, and behaviors leading to accidents. This combination may also increase the likelihood of drug-related blackouts, memory issues, and long-term cognitive problems.
- Increased dehydration: Alcohol’s diuretic properties, coupled with potential exacerbation by marijuana, may lead to increased dehydration.
- Potential issues with elimination: Marijuana’s antiemetic effects hinder vomiting, which, when combined with alcohol, may disrupt the body’s ability to expel excess alcohol, potentially increasing the risk of overdose or alcohol poisoning.
- Intensified side effects: Combining alcohol with marijuana products amplifies the side effects associated with the drug, including anxiety, allergic reactions, or hallucinations.
- Long-term effects: Chronic co-use of these substances increases the risk of developing cardiovascular issues, liver disease, kidney disease, gastrointestinal problems, cancer, and compromised immune system function.
- Complicated physical dependence: Chronic abuse of both substances can exacerbate physical dependence on either alcohol or cannabis, leading to complex withdrawal issues.
- Psychological effects: Chronic use of either substance is associated with various mental illnesses. Combining both drugs may heighten the risk of being diagnosed with co-occurring mental health conditions like depression or anxiety disorders.
Is Mixing Alcohol and Marijuana Bad for You?
Research exploring the chronic use of alcohol and marijuana is still in its early stages. As marijuana legalization progresses in various states, studies examining the frequency and potential long-term effects of this dual consumption are anticipated to advance.
The combination of alcohol and marijuana presents potential risks and adverse effects that should be carefully considered by anyone intending to mix these substances. While some people may engage in this practice without apparent immediate harm, there are significant dangers associated with co-using these substances. The interaction between alcohol and marijuana can lead to heightened intoxication, impaired cognitive functions, and an increased risk of overdose or poisoning. Beyond this, the long-term effects of chronic co-use may contribute to various health issues, both physical and psychological.
People should develop an awareness of potential complications, including intensified side effects, impaired judgment, and the risk of developing physical and psychological dependence on either substance. Understanding the potential negative impact on hydration, elimination processes, and the increased potential for allergic reactions is essential for making informed decisions about co-use.
As research in this area continues to evolve, individuals are encouraged to stay informed about the latest findings regarding the co-use of alcohol and marijuana. Seeking guidance from healthcare professionals and staying attuned to personal health and well-being is crucial for making informed choices about substance use.
Marijuana and Alcohol Withdrawal
When considering the potential consequences of mixing marijuana and alcohol, it may be necessary to address withdrawal effects. Both substances are known to induce physical dependence, and individuals who chronically combine alcohol and marijuana may experience compounded withdrawal challenges.
Alcohol withdrawal
Alcohol withdrawal is a well-documented phenomenon associated with chronic use. Abrupt cessation of alcohol can lead to symptoms ranging from mild anxiety and tremors to severe complications such as seizures and DTs (delirium tremens). Combining alcohol with marijuana can complicate the withdrawal process, potentially exacerbating the severity of symptoms and prolonging the recovery period.
Marijuana withdrawal
While marijuana withdrawal is often considered less severe than alcohol withdrawal, it is still recognized by APA (American Psychiatric Association). Symptoms may include irritability, insomnia, loss of appetite, and mood disturbances. Chronic co-use of marijuana and alcohol can intensify withdrawal symptoms related to either substance, making the cessation process more challenging.
Seeking professional guidance and support during this process is advisable, as healthcare professionals can provide personalized strategies to manage withdrawal symptoms and facilitate a safer and more comfortable recovery.
