The multibillion-dollar California cannabis (Cannabis sativa, marijuana) industry employs an unknown number of seasonal workers, including many immigrants. Most production occurs in the remote, rural, far-northern counties where farms may be hours by vehicle from the nearest town. While licenses for cannabis cultivation became available following legalization in California for adult recreational use in 2016, most cannabis— about 80%—is still grown on unlicensed farms. Cannabis is a labor-intensive crop, and the skilled and time-consuming task of hand-trimming flowers is the most common seasonal job in the industry. Some immigrant workers return for multiple cannabis harvest seasons and are attracted to the work by an interest in the cannabis culture and consumption or the opportunity to earn enough money in several months to live the rest of the year in their home country. Others are farmworkers moving from work in traditional crops for the relatively higher pay in the cannabis industry. Seasonal cannabis workers are exposed to many of the physical hazards found in all agricultural workplaces, like dust, pesticides, and injuries; another commonality with California’s traditional agricultural workforce is vulnerability to structural violence stemming from factors related to race, gender, immigration status, and employer/employee power imbalance. Cannabis workers are also uniquely affected by the intersections of these structural factors with the isolated and remote nature of cannabis farms and the ongoing criminalization of the industry. In this article we present the results of a qualitative study of the occupational health and safety of Mexican and South American immigrant seasonal cannabis workers who have previous cannabis industry-specific skills and experience. Workers were recruited using a peer-recruitment method, with 25 participants in three online focus group discussions on a range of occupational health and safety topics. This qualitative descriptive analysis is focused on experiences of structural violence and wage theft. [ABSTRACT FROM AUTHOR]

BACKGROUND: The presence of contaminants in cannabis presents a potential health hazard to recreational users and susceptible patients with medical conditions. Because of the federally illegal status of cannabis, there are no unified regulatory guidelines mitigating the public health risk of cannabis contaminants. OBJECTIVE: To inform further research and provide solutions to the public health risk of cannabis contaminants at a national level, we examined the current landscape of state-level contaminant regulations, and cannabis contaminants of concern, as well as patient populations susceptible to contaminants. METHODS: We examined the regulatory documents for medical and recreational cannabis in all legalized U.S. jurisdictions and compiled a complete list of regulated contaminants, namely, pesticides, inorganics, solvents, microbes, and mycotoxins. We data mined the compliance testing records of 5,654 cured flower and 3,760 extract samples that accounted for ~6% of California's legal cannabis production in 2020-2021. We also reviewed the publicly available medical cannabis use reports to tabulate the susceptible patient populations. RESULTS: As of 18 May 2022, 36 states and the District of Columbia listed a total of 679 cannabis contaminants as regulated in medical or recreational cannabis, including 551 pesticides, 74 solvents, 12 inorganics, 21 microbes, 5 mycotoxins, and 16 other contaminants. Different jurisdictions showed significant variations in regulated contaminants and action levels ranging up to four orders of magnitude. A failure rate of 2.3% was identified for flowers and 9.2% for extracts in the California samples. Insecticides and fungicides were the most prevalent categories of detected contaminants, with boscalid and chlorpyrifos being the most common. The contaminant concentrations fell below the regulatory action levels in many legalized jurisdictions, indicating a higher risk of contaminant exposure. Cannabis use reports indicated usage in several patient populations susceptible to contamination toxicity, including cancer (44,318) and seizure (21,195) patients. DISCUSSION: Although individual jurisdictions can implement their policies and regulations for legalized cannabis, this study demonstrates the urgent need to mitigate the public health risk of cannabis contamination by introducing national-level guidelines based on conventional risk assessment methodologies and knowledge of patients' susceptibility in medical use.

Introduction: Little is known about the possible impacts of recreational marijuana legalization on alcohol and marijuana co-use among underage youth. This study examines the association between recreational marijuana legalization in California in 2016 and alcohol and marijuana co-use among adolescents. Additional analyses investigate the associations between recreational marijuana legalization and co-use among past 30-day drinkers and marijuana users and the frequency of alcohol and marijuana use among co-users.Methods: This study used annual cross-sectional data from 7th, 9th, and 11th graders (N=3,319,329) who participated in the California Healthy Kids Survey from 2010-2011 to 2018-2019. Measures included past 30-day alcohol and marijuana use and student demographic characteristics, survey year, pre-post recreational marijuana legalization, and urbanicity. Multilevel regression analyses were conducted in 2021.Results: Recreational marijuana legalization was associated with greater odds of past 30-day alcohol and marijuana co-use in the total sample (OR=1.06, 95% CI=1.05, 1.07). Recreational marijuana legalization was more strongly associated with co-use among adolescents who reported past 30-day alcohol use (OR=1.58, 95% CI=1.52, 1.62) and heavy drinking (OR=1.25, 95% CI=1.21, 1.29) but was inversely related to co-use among past 30-day marijuana users (OR=0.76, 95% CI=0.74, 0.78). Among past 30-day co-users, there was a positive association with the frequency of marijuana use (β=0.36, SE=0.07).Conclusions: Recreational marijuana legalization may increase the risk of alcohol and marijuana co-use among adolescents. Greater restrictions on the numbers of alcohol and marijuana retail outlets and hours of operation and advertising and higher taxes on alcohol and marijuana products may help reduce the availability of these substances to adolescents.
