Recent data challenges the widely held perception of Generation Z as a more health-conscious and moderate generation when it comes to substance use. A new analysis of data from the UK’s Millennium Cohort Study reveals a significant rise in binge drinking and drug experimentation among young adults in their early twenties, prompting concerns about potential long-term health and social consequences. While often characterized as “sober curious,” this cohort appears to be engaging in risky behaviors at rates comparable to, and in some cases exceeding, those of previous generations at the same age.
The study, conducted by researchers at University College London (UCL), tracked nearly 10,000 individuals born between 2000 and 2002, comparing their behaviors at ages 17 and 23. The findings indicate a substantial increase in both alcohol and drug use during this transitional period. This surge in risky behaviors raises questions about the factors influencing these trends and the effectiveness of current prevention strategies. Understanding these patterns is crucial for developing targeted interventions to support the well-being of young adults.
The data reveals a concerning trend: almost seven in ten (68%) 23-year-olds reported binge drinking in the past year, a 15 percentage point increase from the 53% who reported doing so at age 17. Binge drinking is defined as consuming six or more alcoholic drinks in a single sitting. Nearly a third (29%) of 23-year-olds admitted to binge drinking at least monthly, a significant jump from the 10% who engaged in this behavior at age 17. This increase is particularly noteworthy given the ongoing public health campaigns aimed at reducing harmful alcohol consumption.
The Rise in Substance Use Among Gen Z
Beyond alcohol, the study also documented a marked increase in drug use among young adults. Nearly half (49%) of those aged 23 reported having tried cannabis, compared to 31% at age 17 – an 18 percentage point increase. Perhaps more alarming is the tripling of experimentation with “harder” drugs, such as cocaine, ketamine, and ecstasy, rising from 10% at age 17 to 32% at age 23. The frequency of use of these harder drugs also increased, with 8% reporting use 10 or more times in the past year, up from 3% at age 17. This escalation in drug experimentation underscores the need for comprehensive substance abuse prevention programs.
The increase in risky behaviors isn’t limited to alcohol and drugs. The study also found a rise in other potentially addictive behaviors. Approximately 32% of the cohort reported gambling at age 23, whereas only 4% described their gambling as problematic. Daily vaping increased significantly, from 3% at age 17 to almost one in five (19%) at age 23. Cigarette smoking rates remained relatively stable, with a slight increase from 8% to 9% during the same period. These findings suggest a broader pattern of risk-taking behavior among young adults, extending beyond traditional substance use.
Why the Increase? Factors at Play
Dr. Aase Villadsen, the lead author of the study, noted that the findings challenge the narrative of Gen Z as a generation increasingly abstaining from alcohol. “Recent reports have suggested that young people are increasingly turning their backs on drinking alcohol compared to earlier born generations. However, our new study appears to show that this might not be the case for some members of Gen Z as they reach their early 20s,” she stated. This suggests that the perceived shift towards moderation may be more pronounced during adolescence and early teenage years, with behaviors changing as young people transition into adulthood.
Several factors may contribute to this increase in risky behaviors. Late adolescence and early adulthood are periods of significant life changes, including increased independence, exposure to new social environments, and heightened stress levels. These transitions can create vulnerabilities that increase the likelihood of experimentation with substances and other risky behaviors. The availability and affordability of alcohol and drugs, coupled with targeted marketing strategies, can also play a role. The influence of peer pressure and social norms should not be underestimated, as young adults often engage in behaviors to fit in or cope with social anxieties.
Dr. Katherine Severi, chief executive of the Institute of Alcohol Studies, emphasized the particular vulnerability of young people to the effects of alcohol. “Young people are particularly vulnerable to alcohol’s effects as the brain continues to develop into the mid-20s,” she warned. This developmental stage makes the brain more susceptible to the harmful effects of alcohol, potentially leading to long-term cognitive and behavioral problems. Severi also highlighted the role of the alcohol environment, particularly on university campuses, where affordability, availability, and promotion contribute to heavy drinking. She argued that universities have a “duty of care” to protect students and ensure that commercial relationships with alcohol companies do not compromise student health and well-being.
The University Environment and Alcohol Consumption
The study’s findings regarding university students are particularly concerning. Higher rates of heavy drinking were observed among those pursuing higher education, suggesting that the university environment may exacerbate existing risk factors. This is likely due to a combination of factors, including increased social opportunities, readily available alcohol, and a culture that often normalizes heavy drinking. The presence of alcohol sponsorships and promotions on campus can further contribute to this environment. Addressing these issues requires a multi-faceted approach, including stricter regulations on alcohol advertising, increased access to mental health services, and the promotion of responsible drinking campaigns.
The findings align with broader concerns about the impact of the COVID-19 pandemic on young people’s mental health and well-being. Lockdowns, social isolation, and economic uncertainty may have contributed to increased stress, anxiety, and depression, potentially leading to increased substance use as a coping mechanism. The long-term consequences of the pandemic on this generation are still unfolding, and ongoing monitoring of substance use trends is essential.
Implications for Public Health and Policy
The rise in binge drinking and drug use among Gen Z has significant implications for public health and policy. It underscores the need for targeted interventions aimed at preventing substance abuse and promoting healthy behaviors. These interventions should be tailored to the specific needs of young adults and address the underlying factors that contribute to risky behaviors. This includes providing comprehensive education about the risks of alcohol and drugs, increasing access to mental health services, and creating supportive environments that promote well-being.
Dr. Villadsen emphasized the importance of focusing on at-risk groups, such as young males, who are disproportionately affected by gambling problems and drug use. “Policy interventions, education and advice should be aimed at the most at-risk groups, such as young males, who are around seven times more likely to report having gambling difficulties than females, and are more likely to use harder drugs,” she explained. This targeted approach can maximize the impact of prevention efforts and ensure that resources are allocated effectively.
addressing the broader social and environmental factors that contribute to substance use is crucial. This includes regulating the availability and affordability of alcohol and drugs, restricting alcohol advertising, and creating policies that support healthy lifestyles. Collaboration between government agencies, healthcare providers, educational institutions, and community organizations is essential to create a comprehensive and coordinated response.
The Millennium Cohort Study provides valuable insights into the evolving behaviors of Gen Z. The full briefing paper detailing the findings on substance use and addictive behaviors will be published on the CLS website. Continued monitoring of these trends is essential to inform evidence-based policies and interventions that protect the health and well-being of young adults.
As researchers continue to analyze the data and explore the underlying causes of these trends, addressing the rise in risky behaviors among Gen Z requires a comprehensive and collaborative approach. The health and future of this generation depend on our ability to understand the challenges they face and provide them with the support they need to thrive.
Further research is expected to be released in the coming months, providing a more detailed analysis of the factors driving these trends. We will continue to monitor these developments and provide updates as they develop into available.
