Cannabis beverages may help people drink less alcohol

Recent survey data suggests that cannabis-infused beverages may serve as an effective tool for individuals looking to curb their alcohol consumption. People who incorporated these drinks into their routines reported reducing their weekly alcohol intake and engaging in fewer episodes of binge drinking. The findings were published in the Journal of Psychoactive Drugs.

Alcohol consumption is a well-documented public health concern. It is linked to nearly 200 different health conditions. These include liver disease, cardiovascular issues, and various forms of cancer.

While total abstinence is the most effective way to eliminate these risks, many adults choose not to stop drinking entirely. This reality has led public health experts to explore harm reduction strategies. The goal of harm reduction is to minimize the negative consequences of substance use without necessarily demanding complete sobriety.

Cannabis is increasingly viewed through this harm reduction lens. It generally presents fewer physiological risks to the user compared to alcohol. The legalization of cannabis in many U.S. states has diversified the market beyond traditional smokable products. Consumers can now purchase cannabis-infused seltzers, sodas, and tonics. These products are often packaged in cans that resemble beer or hard seltzer containers.

This similarity in packaging and consumption method is notable. It allows users to participate in the social ritual of holding and sipping a drink without consuming ethanol. Jessica S. Kruger, a clinical associate professor of community health and health behavior at the University at Buffalo, led an investigation into this phenomenon. She collaborated with researchers Nicholas Felicione and Daniel J. Kruger. The team sought to understand if these new products are merely a novelty or if they serve a functional role in alcohol substitution.

The researchers designed a study to capture the behaviors of current cannabis users. They distributed an anonymous survey between August and December of 2022. Recruitment took place through various channels to reach a broad audience.

The team placed recruitment cards with QR codes in licensed dispensaries. They also utilized email lists from these businesses. Additionally, they posted links to the survey on nearly 40 cannabis-related communities on the social media platform Reddit.

The final analytic sample consisted of 438 adults. All participants had used cannabis within the past year. The survey incorporated questions from the Behavioral Risk Factor Surveillance System. This is a standard tool used by the Centers for Disease Control and Prevention to track health-related behaviors. The researchers used these questions to assess alcohol consumption frequency and intensity.

The study aimed to compare the behaviors of those who drank cannabis beverages against those who used other forms of cannabis. It also sought to compare alcohol habits before and after individuals began consuming cannabis drinks. Roughly one-third of the respondents reported using cannabis beverages. These users typically consumed one infused drink per session.

The researchers found differences in substitution behaviors between groups. Participants who consumed cannabis beverages were more likely to report substituting cannabis for alcohol than those who did not drink them. The data showed that 58.6 percent of beverage users reported this substitution. In contrast, 47.2 percent of non-beverage users reported doing so.

The study provided specific data regarding changes in alcohol intake levels. The researchers asked beverage users to recall their alcohol consumption habits prior to adopting cannabis drinks. Before trying these products, the group reported consuming an average of roughly seven alcoholic drinks per week. After they started using cannabis beverages, that average dropped to approximately 3.35 drinks per week.

Binge drinking rates also saw a decline. The researchers defined a binge drinking episode based on standard gender-specific thresholds. Before initiating cannabis beverage use, about 47 percent of the group reported binge drinking less than once a month or never. After incorporating cannabis drinks, the proportion of people reporting this low frequency of binge drinking rose to nearly 81 percent.

Most participants did not replace alcohol entirely. The survey results indicated that 61.5 percent of beverage users reduced their alcohol intake. Only about 1 percent reported stopping alcohol consumption completely.

A small minority, roughly 3 percent, reported increasing their alcohol use. This suggests that for most users, cannabis beverages act as a moderator for alcohol rather than a complete replacement.

The study also examined the potency of the beverages being consumed. Most respondents chose products with lower doses of Tetrahydrocannabinol (THC). Two-thirds of the users drank beverages containing 10 milligrams of THC or less. This dosage allows for a milder experience compared to high-potency edibles. It may facilitate a more controlled social experience similar to drinking a glass of wine or a beer.

Daniel J. Kruger, a co-author of the study, noted the potential reasons for these findings. He suggests that the similarity in the method of administration plays a role. People at parties or bars are accustomed to having a drink in their hand. A cannabis beverage allows them to maintain that behavior. It fits into the social context more seamlessly than smoking a joint or taking a gummy.

There are limitations to this research that require consideration. The study relied on retrospective self-reports. Participants had to recall their past alcohol consumption. This relies on memory and can be subject to bias. The sample was also a convenience sample rather than a nationally representative one. Many respondents were recruited from New York State dispensaries or specific online communities.

The researchers also point out potential risks associated with these products. Cannabis beverages and edibles have a slower onset of effects compared to inhalation. It takes time for the digestive system to process the cannabinoids. This delay can lead inexperienced users to consume more than intended. Accidental overconsumption can result in negative physical and mental health outcomes.

Furthermore, there is the issue of dual use. Most participants continued to drink alcohol, albeit in smaller quantities. Combining alcohol and cannabis can intensify impairment. The authors note that this interaction needs further study to ensure public safety.

Future research is necessary to validate these preliminary findings. The authors suggest that longitudinal studies would be beneficial. Such studies would track individuals over time rather than relying on past recall. This would provide a clearer picture of whether the reduction in alcohol use is sustained in the long term.

Public education will be key as this market expands. Consumers need to understand the differences between alcohol and cannabis impairment. They also need accurate information regarding dosing and onset times. Policies that ensure clear labeling and child-proof packaging remain essential for harm reduction.

Despite the caveats, the study offers a new perspective on alcohol harm reduction. It highlights a potential avenue for individuals seeking to lower their alcohol intake. As the market for these beverages grows, understanding their role in consumer behavior becomes increasingly important for public health officials.
