Serving Alcohol to Obviously Intoxicated Patrons

Serving Alcohol to Obviously Intoxicated Patrons

Klein Buendel scientists and staff are co-authors on a new publication of research results with scientists from the Pacific Institute for Research and Evaluation (PIRE) in the Journal of Studies on Alcohol and Drugs (JSAD). The study, led by PIRE, examines alcohol over-service at bars, nightclubs, restaurants, etc. in California which is associated with driving while intoxicated, violence, and other problems.

Three hundred licensed bars, night clubs, restaurants, etc. were sampled in 2022 in nine counties representing the San Francisco Bay Area. Combination pseudo-patron and observer teams visited each on-premise establishment where the pseudo-patrons attempted to buy alcohol while displaying obvious signs of intoxication. The JSAD paper describes characteristics of the establishments, servers, pseudo-patrons, and time/date of purchase attempt that may be associated with the refusal of alcohol service.

In total, 21% of the establishments refused alcohol service to pseudo-patrons. Descriptive and regression analyses were conducted and are described in detail in the JSAD publication. According to the authors, “No establishment or server characteristics were significantly associated with service refusal in logistic regression analysis; nor were month, day, or time.” However, service refusal was significantly more likely for female pseudo-patrons and pseudo-patrons displaying obvious or very obvious signs of intoxication.

The authors assert that the study indicates that alcohol over-service to obviously intoxicated patrons remains common at licensed on-premises establishments. Mandatory responsible beverage service training of servers and enforcement of alcohol over-service laws was recently enacted in California, which may help to reduce over-service and its related problems.

Decreasing access to marijuana by alcohol-impaired customers

Decreasing access to marijuana by alcohol-impaired customers

Recreational marijuana markets appear to be contributing to morbidity and mortality due to polysubstance impaired driving and other harms by selling a social intoxicant (marijuana) to already intoxicated customers. Impairment increases when marijuana is combined with alcohol, making driving particularly risky and also contributing to other injuries and violence. In recreational marijuana markets, deterrence efforts to reduce impaired driving directed at drivers face challenges due to dispute over THC levels in per se laws and lack of valid field sobriety tests.

A team of researchers at Klein Buendel, the Pacific Institute for Research and Evaluation, and NORC at the University of Chicago, is launching a new 5-year research project to study an alternative prevention approach — decrease access to marijuana by alcohol-impaired customers. The goal of this study is to test the effectiveness of a policy and training intervention in the state-licensed recreational marijuana market in a Northwest State, where state law bans sales to apparently-intoxicated customers. It combines policy efforts by state regulators to increase deterrence of the state’s law and motivate store management to comply and training of store personnel in skills to recognize intoxication and refuse sales, using a responsible marijuana vendor online training developed by the research team.

Specific Aims

Aim 1: Conduct pseudo-intoxicated patron (PiP) assessments at state-licensed recreational marijuana stores in the state’s largest metropolitan area in Year 1.

Aim 2: Implement a policy and training (PT) intervention in Year 2 designed to increase compliance with the state law prohibiting sale of recreational marijuana products to apparently-intoxicated customers with a subsample of stores, assigned at random, that intends to: a) make owners/managers of recreational marijuana stores aware of the state’s law prohibiting sales of marijuana to apparently-intoxicated customers, b) increase their risk perception and motivation to comply with this law, and c) train store personnel in skills needed to recognize signs of intoxication in customers and refuse sales.

Aim 3: Compare PT intervention stores to usual and customary policy and training stores in a randomized controlled trial by posttesting state-licensed recreational marijuana stores in the large metro area with PiP assessments for refusal of sales in Year 3.

Aim 4: Estimate impact of the PT intervention on refusal to PiPs by implementing the PT intervention with the remaining stores in Year 3 in a partial cross-over design and assessing state-licensed stores with the PiP protocol in Year 4 and in Year 5.

The research is innovative and high impact by testing one of the first interventions to prevent recreational marijuana sales to apparently-intoxicated customers in one of the first states to ban such sales to reduce the risk of polysubstance impaired driving and other harms. The design allows for reproducibility by using a partial crossover. The PT intervention can be a model intervention to improve compliance with regulations on recreational marijuana sales in other states that have legalized recreational marijuana or that are considering legalization. 

The research is supported by a grant from the National Institute on Alcohol Abuse and Alcoholism (AA031591). Dr. W. Gill Woodall and Dr. David Buller from Klein Buendel are the Project’s Multiple Principal Investigators. Dr. Robert Saltz from the Pacific Institute for Research and Evaluation and Mr. James Fell from NORC are collaborating Co-Investigators.

Sales of Recreational Cannabis to Alcohol-Intoxicated Customers

Sales of Recreational Cannabis to Alcohol-Intoxicated Customers

To prevent harm, some U.S. states have laws prohibiting the sale of recreational marijuana to alcohol-intoxicated customers. In a recent publication in the International Journal of Drug Policy, Klein Buendel researchers and collaborators evaluated an online responsible marijuana vendor (RMV) training program – Train to Tend – and its performance at deterring sales to apparently alcohol-intoxicated customers in recreational cannabis stores. Much like the training of responsible alcohol sales practices, RMV training may prove beneficial for helping to keep customers and communities safe.

One hundred fifty stores from Colorado, Oregon, and Washington were enrolled in the randomized controlled trial. Half of the stores were randomly selected to receive Train to Tend training. One of the five online training modules addressed recognizing signs of impairment and intoxication, refusing sales to intoxicated patrons, and understanding the risks of driving under the influence of cannabis.

The evaluation employed pseudo-patron pairs, one of which displayed obvious signs of alcohol intoxication. The refusal of cannabis sales to the pseudo-intoxicated buyers was very low. In some cases, store personnel made comments or expressed suspicion towards buyers’ behavior, but continued with the sale nonetheless. Refusal rates between intervention and control stores were not significantly different. Overall, responsible marijuana vending practices alone did not appear to influence the reduction of marijuana sales to customers with obvious signs of alcohol intoxication. A full description of the methods, results, and discussion can be found in the publication.

Refusal of Pseudo-intoxicated Customers at Retail Marijuana Stores

Refusal of Pseudo-intoxicated Customers at Retail Marijuana Stores

Klein Buendel Senior Scientist, Dr. David Buller presented a poster at the Society for Prevention Research Annual Meeting in San Francisco, California in May. The poster presented insights on whether personnel in recreational marijuana stores refuse sales to buyers who appear to be intoxicated.

Recreational marijuana is sold by state-licensed stores in seven U.S. states. Like alcohol, sales are prohibited to persons younger than age 21 and sometimes to persons who are apparently intoxicated. A sample of 150 licensed retail stores in Colorado, Oregon, and Washington were selected from state regulatory agency lists. A majority of stores sold both recreational and medical marijuana. The sample was stratified between the largest metropolitan area in each state (Denver, Portland, and Seattle) and nearby regions with smaller cities.

Pseudo-patron assessment teams comprised of a ‘buyer’ and an ‘observer’, visited each store once from August to October 2018. Buyers attempted to enter the premises while feigning obvious signs of intoxication (for example: slurred speech, stumbling, dropped change or ID) and attempted to purchase a low-cost cannabis product. Observers recorded whether buyers gained entry and if the clerk offered to sell marijuana (no actual purchases were made).

Refusal rates were rare. Overall, refusal rates were slightly higher in the states of Colorado and Oregon than in Washington. A state law that explicitly prohibited sales in Oregon may have slightly decreased sales there, while refusals in Colorado may be attributed to the wide-scale use of security guards checking IDs at entrances. These high rates of sales to apparently intoxicated customers are a cause for concern, especially in light of research indicating that the combination of alcohol and marijuana intoxication appears to severely impair driver performance.

Implementation and Effectiveness of an Online Responsible Vendor Training Program for Recreational Marijuana Stores

Implementation and Effectiveness of an Online Responsible Vendor Training Program for Recreational Marijuana Stores

Since 2012, nine U.S. States and the District of Columbia (DC) have legalized recreational marijuana, and several other states are looking to follow suit in coming years. At the outset of the legalization of recreational marijuana, the U.S. Department of Justice (DOJ) informed these states that they must put robust constraints into place that prevent youth access to marijuana. To accomplish this DOJ objective, Dr. David Buller and Dr. Gill Woodall from Klein Buendel (KB), and their co-authors created Train To Tend, an online responsible marijuana vendor (RMV) training program that aims to provide retail marijuana staff with the knowledge and skills they need in order to sell marijuana responsibly, and keep their communities safe. In a recent e-publication in the Journal of Public Health Management and Practice, the authors report the results of the implementation and evaluation of Train To Tend and what these results could mean for future research and policy.

Train To Tend was created with input from state regulators and local law enforcement personnel, curriculum standards published by the Colorado Marijuana Enforcement Division, interviews with recreational marijuana store personnel (n=15), and usability testing of a prototype training with store personnel (n=19) in Colorado and Washington State. Of all the input from these various stakeholders, retail marijuana store personnel reported that comprehensive training in responsible sales practices was uncommon in the industry. Coupled with the DOJ objective of preventing youth access to marijuana, this finding demonstrated a need for RMV.

Once all stakeholder input was reviewed, Train To Tend was created, and the training ultimately contained five modules: state laws and regulations, ID checking, health effects of marijuana, customer service practices including recognizing intoxicated patrons, and rules of the trade.

In a randomized controlled trial, the training was tested using a random sample of state-licensed recreational marijuana stores (n=225) in Colorado, Oregon, and Washington State. One hundred twenty-five stores were randomly selected to receive Train To Tend, while the remaining 100 stores received the usual and customary training in their state. In total, 420 store employees completed Train To Tend in 2017 and 2018. Pre- and post-training surveys were administered to Train To Tend trainees to gauge their perceptions of self-efficacy toward RMV practices, as well as their ratings of usability for Train To Tend.

Results revealed that the training improved trainees’ ability to check IDs, use their state’s inventory tracking system, and spot intoxicated customers. Also, most trainees felt very confident using the training, rated the training as user-friendly, and thought that the information and skills learned in the training would help keep their communities safe.

Overall, trainees’ improvement in confidence to engage in responsible sales practices, as well as the high levels of usability for Train To Tend they reported, suggests that programs like Train To Tend are feasible and potentially effective at training staff in recreational marijuana markets. In addition, this randomized-controlled trial provides a solid foundation upon which future research into RMV trainings can be built. This type of research is imperative to ensure the safety of customers that live in early-adopting recreational marijuana markets like Colorado, Oregon, and Washington State. By conducting research like this when recreational marijuana legalization is in its early stages, many unforeseen problems can be mitigated before they grow too large, and ultimately the public can be kept safer.
