“…These results are in line with other findings indicating that screen time clusters with other risk behaviours among youth (Carson et al, 2011; Iannotti et al, 2009). This is in contrast with other research that has examined the relationship between cannabis use and screen time and found null results (Sampasa-Kanyinga et al, 2018; Zuckermann et al, 2019). This is potentially because this literature has dichotomized screen time based on the recommended 2 h limit in the Canadian 24 Hour Movement Guidelines whereas we examined this variable continuously (Tremblay et al, 2016).…”

Introduction In this study we examined the co-occurrence of alcohol, cannabis, and tobacco among a large cohort of grade 12 students in Canada, and then explored if the age of initiation of these substances was associated with moderate-to-vigorous physical activity (MVPA), screen time, and BMI. Methods This cross-sectional study used student-level data from grade 12 students in years 1 to 5 (2012–2016) of the COMPASS study. Random intercept linear regression models were used to examine the impact of age of initiation of alcohol, cannabis, and tobacco use on student average daily physical activity, daily screen time and BMI. Results Twenty-eight percent of students had only tried one substance with alcohol being the most reported single substance used (25%). The most common co-occurrence was students reporting having tried all three substances (27%). Nineteen percent of students reported no substance use by grade 12. Younger age of first use of alcohol was associated with increased MVPA in grade 12. Earlier initiation of cannabis and tobacco were associated with increased screen time in grade 12. Age of first use of alcohol, cannabis and tobacco were not associated with BMI in grade 12. Conclusion While no specific cut-off age was identified this study indicates that for every year tobacco and cannabis use are delayed among children, there are subsequent reductions to screen time in grade 12. Early initiation of alcohol was associated with increased MVPA in grade 12. Early initiation of alcohol, cannabis and tobacco were not associated with BMI in grade 12.

“…Peters, Bae, Barrington-Trimis, Jarvis, and Leventhal [23] reported on a prevalence of cannabis use during lifetime and within 30 days of 33.9% and 14.9%, respectively, in a sample of 3177 adolescents from Los Angeles (USA) with a mean age of 16 years. Sampasa-Kanyinga, Hamilton, LeBlanc, and Chaput [24] reported on a prevalence of 21.5% for cannabis use within 12 months and a prevalence of 13.9% for cannabis use within 30 days in a sample of 9920 adolescents from Ontario, Canada. Results from adolescents in Spain showed an estimated prevalence of last-year cannabis use of 17.1% in young adults aged 15–34 years [17].…”

“…Additionally, other variables, such as psychological problems, have been associated with cannabis use, either as its cause or as its consequence [21], but that could not be identified because of a lack of psychiatric interviews. Another limitation is the use of corrected p -values, which, as happened in the work by Peters et al [23], turned into nonsignificant some results that would have been significant at p < 0 .05, as used in previous works [19,24]. This is the case with the association between weekly available money and the probability of getting involved in physical assault.…”

This study examined the relations between problematic cannabis use, physical assault, and getting involved in a motor vehicle accident under the influence of cannabis in a sample of adolescents randomly selected from 25 public and semiprivate high schools in Alicante (Spain). Participants (n = 648) completed The Spanish National Standardized Survey about drug use in high school adolescents (ESTUDES, 2017), which includes the cannabis abuse screening test (CAST). Prevalence of cannabis use across the life-span and within the past 30 days was 37.5% and 17.4%, respectively. CAST scores were associated with an increased risk of driving under the effects of cannabis, riding shotgun, and physical assault, but not with an increased risk of having a motor vehicle accident. There were no differences between boys and girls in the association of problematic cannabis use with risky behaviors. This result highlights the importance of comprehensive prevention and education strategies for adolescents at high risk of cannabis use.

In the Gambia like all nations, drug abuse is seen as a social and health problem that has many serious implications for the physical, social, psychological and intellectual development of the victims more especially, the children. Therefore, it continues to be a concern to families, community leaders, educators, social workers, health care professionals, academics, government and its development partners. Though there are some studies on drug abuse, there is none on children and drug abuse focusing on the street children the most vulnerable category. Street children are hypothesized to be more at risk of any epidemic including drug abuse. This study sought to determine the risk and prevalence of drug abuse among street children focusing on those in the car parks. The research was focused on six critical areas: level of knowledge of drug abuse, perception towards it, level of knowledge of the causes of it in the community and among street children, level of knowledge of negative impacts of it, level of knowledge of the preventive methods; and level of knowledge of the support services and treatments needed by victims.A structured questionnaire was used to collect the data from thirty-five participants (i.e. one driver and six casual apprentices from each of the five car parks) were interviewed. The data was presented and analyzed using tables and percentage. The findings revealed among other things, that there is high level of awareness of drug abuse but the feelings towards it are mixed. Like other children, street children are abusing drugs mainly due to peer influence with the ultimate objective of getting high to relief stress, group recognition, desire to be trusted by peers, etc. Similarly, participants are highly aware of the negative impacts encompassing fighting, stealing, mental illness, etc. To finance the behavior, victims are engaged in all types of dangerous antisocial behavior including romantic ones exposing them to a range of diseases including STIs and HIV/AIDS. Marijuana is the most commonly abused drug. Though in the minority, some have started experimenting cocaine/coke, hashish; and heroin. While participants have good knowledge of the critical methods to fight drug abuse, the support services needed by victims, victims are mostly reluctant to seek the services not only because they are hard to find but fear societal stigmatization, exclusion and discrimination and professionals' maltreatments.
