This study compared 18 low-risk drinking guidelines that were gathered from Canadian government agencies, non-government agencies, medical bodies, and public and private agencies involved in the treatment of addictions. The results show that two sets of guidelines are predominantly used in Ontario. The formulation of these guidelines was entirely independent and their intended audiences are also different. However, a direct comparison of the two guidelines shows that differences are more apparent than real. This study also examines the literature evaluating low-risk drinking guidelines. Very little literature exists on evaluating low-risk drinking guidelines as vehicles for primary prevention and it is not known to what extent such guidelines influence knowledge and drinking behaviour. Future low-risk drinking recommendations should be evaluated for knowledge about standard drink units, awareness of the guidelines, use of materials and aids included in the dissemination program, and changes in behaviour from campaign exposure.

INTRODUCTION: Changes to federal legislation allowed nicotine-based e-cigarettes legal entry into the Canadian market in 2018. This included pod-type e-cigarettes (pods), such as JUUL, that were later found to be associated with steeply increasing prevalence and greater frequency of e-cigarette use among US and Canadian youth. Multiple studies of risk factors of JUUL use and use initiation have been conducted among various population groups in the US, but little evidence exists pointing to similar risk factors of pod use among Canadian youth and young adults. Understanding these risk factors can inform use prevention and intervention strategies in Canadian and other jurisdictions. METHODS: A total of 668 Canadian youth and young adults recruited by the 2018-19 Youth and Young Adult Panel Study were provided a baseline survey 3 months before and a follow-up survey 9 months after the relaxation of federal nicotine e-cigarette regulations. We used multivariable logistic regression to understand and rank importance of baseline predictors of future pod use among respondents. RESULTS: Past-month cannabis use (OR [odds ratio]=2.66, 95% CI:1.66–4.21, p<0.001), established cigarette use (OR = 3.42, 1.53–7.65, p<0.01), past cigarette experimentation (OR = 2.40, 1.34–4.31, p<0.01), having many friends who vaped (OR = 2.15, 1.37–3.34, p<0.001), age below 18 compared to age over 22 (OR = 5.26, 2.63–10.00, p<0.001) and male sex (OR = 1.69, 1.16–2.50, p<0.01) were significant and the most influential predictors of future pod use. CONCLUSION: Similar factors drove pod use among Canadian and US youth and young adults. Appropriate preventive strategies can benefit from considering polysubstance use among high school–aged youth.

OBJECTIVE: : On May 31, 2006, Ontario joined a small group of international jurisdictions to implement legislative restrictions on tobacco point of sale promotions. This study compares the presence of point of sale promotions in the retail tobacco environment from three surveys: one prior to and two following implementation of the legislation. METHOD: : Approximately 1,575 tobacco vendors were randomly selected for each survey. Each regionally-stratified sample included equal numbers of tobacco vendors categorized into four trade classes: chain convenience, independent convenience and discount, gas stations, and grocery. Data regarding the six restricted point of sale promotions were collected using standardized protocols and inspection forms. Weighted estimates and 95% confidence intervals were produced at the provincial, regional and vendor trade class level using the bootstrap method for estimating variance. RESULTS: : At baseline, the proportion of tobacco vendors who did not engage in each of the six restricted point of sale promotions ranged from 41% to 88%. Within four months following implementation of the legislation, compliance with each of the six restricted point of sale promotions exceeded 95%. Similar levels of compliance were observed one year later. Grocery stores had the fewest point of sale promotions displayed at baseline. Compliance rates did not differ across vendor trade classes at either follow-up survey. Point of sale promotions did not differ across regions in any of the three surveys. CONCLUSION: : Within a short period of time, a high level of compliance with six restricted point of sale promotions was achieved.

"Studies requiring the collection of biological specimens are often difficult to perform and costly. The authors compare face-to-face and telephone interviews to determine which is more effective for return of self-collected rectal swabs from subjects living in rural and semi-rural areas of Ontario, Canada. People interviewed face-to-face in 2006-2007 were asked to provide a rectal swab while the interviewer waited. Those interviewed by telephone were sent a package and asked to return the swab by mail, with one follow-up reminder call. Telephone interviewing resulted in a higher response rate for the completion of household and individual-level questionnaires. However, face-to-face interviews resulted in a significantly higher proportion of interviewees who returned swabs making the participation rate higher for this mode of contact (33.7 versus 25.0 percent). Using multivariable logistic regression, higher rates of rectal swab return were associated with face-to-face interviewing while adjusting for the impact of household size and respondent age and sex. For studies requiring the submission of intimate biological samples, face-to-face interviews can be expected to provide a higher rate of return than telephone interviews." (author's abstract)
