Study breakdown

Tobacco and cannabis use correlated with alcohol problems among Czech and Slovak university students during COVID-19

Cross SectionalModerate evidence
The takeaway

Among nearly 3,000 Czech and Slovak university students surveyed during early COVID-19, tobacco and cannabis use were both positively associated with alcohol use disorders, with males at higher risk.

University health services, Central European substance use researchers, student prevention coordinators

Tobacco and cannabis use both associated with alcohol disorders in both countries

What the researchers found

Tobacco and cannabis use were positively associated with alcohol use disorders in both Czech and Slovak student samples. Males were more likely to report alcohol use disorders. In the Czech Republic, dormitory students had lower AUDIT scores, while in Slovakia, dormitory students had higher scores.

Why it matters

The COVID-19 pandemic may have altered substance use patterns among university students. Understanding the clustering of alcohol, tobacco, and cannabis use helps target prevention programs that address polysubstance patterns rather than single substances.

The numbers in context

1,422 Czech + 1,677 Slovak students; 93% CZ and 91% SK drank in past year; tobacco and cannabis positively associated with AUDIT scores; males had higher alcohol disorder risk; dormitory effects opposite between countries

How the study worked

Cross-sectional survey of 1,422 Czech and 1,677 Slovak university students during early COVID-19. Used AUDIT for alcohol, GN-SBQ for tobacco, and CAST for cannabis. Correlation and regression analyses examined substance use associations and demographic factors.

What this study cannot tell us

Cross-sectional during COVID-19 may not reflect normal patterns. Self-reported measures. Convenience sampling of university students. Cannot determine if cannabis/tobacco use causes or results from alcohol problems.

How to read the evidence

Cross-national comparison with reasonable sample sizes, though cross-sectional design during pandemic conditions limits generalizability.

When this study was published

Published in 2021 during early COVID-19.

The bigger picture

The consistent association between cannabis and alcohol problems across two Central European countries reinforces that polysubstance use patterns are relevant for student health services throughout the region, not just in individual national contexts.

Questions still open

  • Did COVID-19 lockdowns change the relationship between cannabis and alcohol use? Why did dormitory living have opposite effects in Czech Republic versus Slovakia?

Common questions

Did cannabis use predict alcohol problems?
Yes. In both Czech and Slovak samples, cannabis use was positively associated with alcohol use disorder scores, consistent with broader literature on polysubstance clustering among young adults.
Was this related to COVID-19?
The data were collected during early COVID-19, which may have influenced substance use patterns. However, the study could not separate pandemic effects from pre-existing associations between substances.
