Co-use of Smokeless Nicotine Products and Marijuana Among Danish Youth Exposed

Research conducted at the University of Southern Denmark has revealed a significant link between the use of smokeless nicotine products and marijuana among Danish youth. A cross-sectional nationwide survey of 15- to 29-year-olds showed that 41.9% had ever used marijuana, with 38.6% reporting frequent use. The study found that factors associated with marijuana use included current use of other nicotine products, being male, having medium- or long-cycle higher education without a current occupation, excessive binge drinking, and living in the Capital Region. Youth who used smokeless nicotine products had markedly higher odds of ever using marijuana, with a 4.13-fold increase in risk.

Key Takeaways:

• The study aimed to identify factors associated with marijuana use and examined the co-use of smokeless nicotine products and marijuana among Danish youth.
• The research used data from a cross-sectional Danish nationwide questionnaire-based survey among 15- to 29-year-olds conducted in 2022, with 6236 participants included in the analyses.
• Factors associated with marijuana use were current use of other nicotine products, being male, having medium- or long-cycle higher education without a current occupation, excessive binge drinking, and living in the Capital Region.
• Youth who used smokeless nicotine products had a 4.13-fold increase in risk of ever using marijuana.
• Among respondents who had ever used marijuana, use of smokeless nicotine products was associated with frequent marijuana use, with a 1.73-fold increase in risk.
• The study found a significant co-use of smokeless nicotine products and marijuana in terms of both marijuana ever-use and frequent marijuana use.
