On the rise or a return to pre-pandemic levels? A cross-sectional online survey on nicotine, alcohol, and illicit drug use among youth.

OBJECTIVES

The COVID-19 pandemic has had unprecedented and deteriorating effects on the mental health of adolescents and young adults. Various studies have described changes regarding substance abuse, but findings are conflicting.

STUDY

DESIGN

We conducted a cross-sectional online survey on nicotine, alcohol, and illicit drug use.

METHODS

From March to May 2023, 502 participants aged 14-24 from a community-based sample completed the questionnaire.

RESULTS

We found a general trend of declining or stable substance use during the first 2 years of the pandemic; however, in the third year (i.e., 2022), substance use returned to pre-pandemic levels or exceeded it. Compared with young adults (age 19-24), adolescents' (age 14-18) use increased more clearly. Participants who scored above the cut-off on screening measures for problematic substance use showed a more pronounced increase in the use of cigarettes and illicit drugs but not of alcohol. Higher alcohol consumption during lockdowns was associated with increased likelihood of current problematic alcohol (odds ratio [OR]: 3.03) and cannabis use (OR: 2.60). Furthermore, individuals who reported increased usage of one psychotropic substance during lockdowns were more likely to have increased their use of other substances as well (OR: 2.66-4.87).

CONCLUSIONS

Although not optimally generalizable due to the retrospective online format and convenience sampling, our results support the notion that special attention ought to be paid to certain subgroups such as younger people and those who already exhibit problematic substance use during the pandemic. Following up on post-pandemic trends in substance use is crucial for developing prevention measures and targeted interventions.
