Substance use and addictive behaviours during COVID-19 confinement measures increased in intensive users: Results of an online general population survey in the Czech Republic
Abstract
Background: The COVID-19 pandemic has affected substance use and other addictive behaviour, however detailed insight is lacking. Material and Methods: Online questionnaire survey on the sample of 3,000 respondents aged 15+ randomly selected from the Czech internet panel using socio-demographic quotas was performed shortly after the end of confinement measures in May 2020 (response rate 35.4%).
Questions covered current prevalence and patterns of substance use (i.e. in the last 12 months) and other forms of addictive behaviours as well as changes in their behaviour during the confinement measures. Responses were provided on categorical scale; a factor of 0 to 2 was assigned to the categories to quantify the changes where 1 means no change.
Results: Respondents reporting the highest frequency of current use, especially the use of alcohol, cannabis and sedatives, further increased their intensity of use during the confinement measures by 5-10% on average, while less frequent users reduced it. The reduction of use during confinement measures increased with decreasing frequency of current use.
Although the same correlation exists in tobacco smokers, decrease in intensity of use was observed also in daily smokers. On the population level, our results suggest a slight increase in total alcohol and sedatives consumption and a significant increase in the total consumption of gaming and social media.
On the contrary, there was a significant reduction in the consumption of tobacco and online gambling (likely due to the ban on sports matches), and a slight reduction in the consumption of cannabis and other illicit drugs. Conclusion: People with intensive patterns of substance use increased their use during confinement measures.
The same concerns gaming and social media. Without this insight the overall picture suggests rather overall reduction of consumption.
Addiction treatment system should prepare for the increase of treatment demand following COVID-19 epidemic.
