Stimulant substance use and gambling behaviour in adolescents. Gambling and stimulant use

Gambling is widely recognized as an important public health problem. Despite the rising use of stimulant substances among adolescents, there are still very few studies focusing on whether adolescents’ use of stimulants is associated with their gambling behaviour. Therefore, the aim of this study was to investigate the association between gambling habits and consumption of stimulants such as coffee, energy drinks, and new psychoactive substances in a sample of Italian adolescents. A survey was conducted in 2017 with a representative sample of Italians between the ages of 14-17 years, comprising 15,833 students attending 201 secondary schools. Logistic regression analyses were run to assess the association between at-risk/problem gambling (O1) and independent predictors: the model included independent variables (coffee, energy drinks and new psychoactive substance consumption) and covariates (demographic variables, social environment variables and risk-taking behaviour variables). A sensitivity analysis was also conducted to examine a second dependent variable regarding any experience of gambling behaviour (O2). Adolescents who were at-risk gamblers or problem gamblers were significantly more likely to consume energy drinks than non-gamblers or not-at-risk gamblers. A similar pattern was seen for consumption of new psychoactive substances. No significant association emerged with coffee consumption. The sensitivity analysis showed that, compared with non gamblers, the group of gamblers had higher odds for frequent coffee consumption, as well as for consumption of energy drinks and/or new psychoactive substances. Screening for gambling and stimulant use may provide important information, as it may be necessary to take action to reduce stimulant substance use as part of efforts to deal with unhealthy gambling habits.
