A shift in patterns of substance use among young adults is raising concerns among public health experts. New research indicates that, contrary to previous assumptions about “Generation Sensible,” rates of binge drinking and drug use have risen sharply among those in their early 20s in the United Kingdom. The findings challenge the notion that this generation is less inclined toward risky behaviors than their predecessors, and highlight a potential need for renewed focus on prevention and support.
The study, conducted by researchers at University College London (UCL), analyzed data from nearly 10,000 individuals born in the UK between 2000 and 2002, tracked through the Millennium Cohort Study. The data revealed a significant increase in both alcohol and drug use between the ages of 17 and 23. Understanding these trends in alcohol consumption and substance use is crucial for developing effective public health strategies.
Binge Drinking on the Rise
The data paints a stark picture regarding alcohol consumption. Almost seven in ten (68%) 23-year-olds reported binge drinking in the past year – defined as consuming six or more alcoholic drinks in one sitting – a 15 percentage point increase from the 53% who reported binge drinking at age 17. Nearly a third (29%) of 23-year-olds reported binge drinking at least monthly, a substantial jump from 10% at age 17. This increase is particularly noteworthy given earlier reports suggesting a decline in alcohol consumption among young people.
Beyond Alcohol: Increased Drug Use
The increase in risky behavior isn’t limited to alcohol. The UCL study as well found a substantial rise in drug use among this cohort. Almost half (49%) of 23-year-olds reported having used cannabis, compared to 31% at age 17. Perhaps more concerning, the proportion of young adults who had tried harder drugs – including cocaine, ketamine, and ecstasy – more than tripled, rising from 10% to 32%. 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.
These findings align with broader reports of increasing substance use among young adults. According to The Guardian, analysts are expressing concern over these trends, particularly as they emerge after a period where Gen Z was often characterized as more cautious.
Other Risky Behaviors and Vulnerable Groups
The study also examined other potentially addictive behaviors. Nearly a third (32%) of participants 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, while cigarette smoking rates remained relatively stable, at 8% and 9% respectively.
Dr. Aase Villadsen, the lead author of the study, emphasized that while experimentation is common during late adolescence and early adulthood, the scale of the increase in these behaviors is concerning. “The sharp rise in many behaviours between adolescence and early adulthood shows how risks intensify during this stage of life,” she stated. The research highlights the need for targeted interventions, particularly for young males, who are reportedly seven times more likely to experience gambling difficulties and are more prone to using harder drugs than their female counterparts.
The Impact of the University Environment
Dr. Katherine Severi, chief executive of the Institute of Alcohol Studies, pointed to the role of the environment, particularly for university students. She noted that universities have a “clear duty of care” to ensure student wellbeing and that commercial relationships with alcohol companies – such as sponsorships – should not compromise student health. Severi also highlighted the influence of affordability, availability, and promotion as key drivers of alcohol-related harm, factors to which many students are readily exposed.
The findings suggest that the perceived shift towards a more health-conscious generation may be more nuanced than previously thought. While some young people may be reducing their alcohol consumption, others are engaging in increased levels of binge drinking and drug use, particularly as they transition into their early 20s.
The full briefing paper, “Substance Use and Addictive Behaviours: Initial Findings From the Millennium Cohort Study at age 23” by Aase Villadsen and Emla Fitzsimons, will be published on the CLS website. Researchers will continue to monitor these trends and explore the underlying factors contributing to these changes in behavior.

The ongoing Millennium Cohort Study will provide further insights into the long-term effects of these behaviors. The next data release is expected in late 2027, offering a more comprehensive understanding of the trajectories of this generation.
