Combining these 2 substances can be harmful to your health
June 11, 2021
In 2012, Colorado voters were the first to approve the recreational use of marijuana. Fast forward to May 2021, and its recreational use is now legal in 17 states, plus Washington, DC and Guam, while medical use is legal in 36 states and four territories. Add the increased access to marijuana to the ubiquity of alcohol and you get the most common form of polysubstance misuse around.
Mixing alcohol and marijuana is a common practice, but using them at the same time can be harmful to your health, according to studies.
According to the CDC, “Using alcohol and marijuana at the same time is likely to result in greater impairment than when using either one alone.” Let’s take a closer look at the health impacts of using alcohol and marijuana simultaneously.
Harms
According to the literature, various studies stress that the biopsychosocial effects of combining alcohol and cannabis are additive. One key concern is impaired driving performance, as concurrent use heightens the risk of collision. The combination can also increase the risk of unprotected sexual intercourse, as well as various other legal, academic, health, and relationship problems.

Chronic use of alcohol and marijuana combined can also decrease cognitive functioning in brain structures such as the hippocampus. These effects are more pronounced when the drugs are used together compared with when the drugs are used separately. Importantly, those who smoke or vape marijuana while drinking can exhibit higher plasma tetrahydrocannabinol (THC) and feel a greater “high.”
The Alcohol and Drug Abuse Institute describes the mixture of alcohol and marijuana as “unpredictable at best. Some users may experience intense paranoia, nausea, and vomiting. The effects of alcohol amplify the effects of marijuana and vice versa.” Both substances impair judgment and motor skills, notes the Institute.
According to the American Addiction Centers, alcohol and marijuana have many similar effects, but act through different mechanisms. "Both result in sedation, alterations in judgment, perceptual effects that include time distortions and even minor hallucinogenic effects, and physical effects that include slowed reflexes and decreased motor coordination," according to the Centers. Marijuana affects the cannabinoid receptors in the brain, whereas alcohol affects several neurological pathways, in particular, the neurotransmitters gamma aminobutyric acid (GABA, an inhibitory neurotransmitter) and NMDA (N-methyl-d-aspartate, an excitatory neurotransmitter).
Brain wiring
Publishing in Nature, researchers assessed dynamic functional network connectivity (dFNC) using functional magnetic resonance imaging (fMRI) among 534 participants grouped according to combinations of nicotine use, marijuana use, and alcohol consumption. They found a trend toward decreased connectivity primarily in areas of sensorial and motor control among those who had a history of marijuana and alcohol use.
They also suggested that the effects of marijuana and alcohol may be additive, thus, once again, reinforcing the notion that alcohol and marijuana combined is worse than either alone.
Motivations
In a novel study, researchers used a questionnaire to assess the motives behind the combined use of alcohol and marijuana in 286 young adults. Importantly, they found that the combined underlying concurrent uses were similar but distinct from the use of either drug separately.
