          Abstract

          Objectives:

          To describe marijuana use by Canadians and their perceptions of risk and harm.

          Design:

          A cross-sectional, structured, online and telephone survey.

          Participants:

          A nationally representative sample of Canadians.

          Methods:

          This survey used random probability sampling and targeted respondents based on age, sex, region and their expected response rate.

          Results:

          Of the 20% of respondents reporting marijuana use in the past 12 months, they were more likely to be younger and male. The most common form of use was smoking, 79%. When asked about harmfulness, 42% and 41% responded that they considered marijuana more harmful than helpful to mental health and to physical health, respectively. When asked about driving under the influence, 71% responded that it was the same as alcohol.

          Conclusion:

          This research is important for health providers and policy makers seeking to maximize public health through clinical and legislative reform of non-medical use of marijuana.

          Objectifs:

          Décrire l'usage de la marijuana chez les Canadiens ainsi que leurs perceptions des risques et dommages.

          Conception:

          Sondage transversal structuré, en ligne et téléphonique.

          Participants:

          Échantillon national représentatif des Canadiens.

          Méthodes:

          Ce sondage a eu recours à un échantillonnage probabiliste aléatoire et à des répondants ciblés selon l'âge, le sexe, la région et le taux de réponse escompté.

          Résultats:

          Les 20 % de répondants qui ont indiqué avoir fait usage de la marijuana au cours des 12 derniers mois sont plus susceptibles d'être des jeunes hommes. La forme d'usage la plus courante est par l'inhalation de fumée, 79 %. Au sujet de la nocivité, 42 % et 41 % ont répondu qu'ils considéraient la marijuana plus dommageable que salutaire pour la santé mentale et la santé physique, respectivement. Au sujet de la conduite sous influence, 71 % ont répondu que c'était comme pour l'alcool.

          Conclusion:

          Cette recherche est importante pour les fournisseurs de services de santé et les responsables de politiques qui veulent maximiser la santé publique par une réforme clinique et législative de l'usage non médical de la marijuana.

          Development of a rational scale to assess the harm of drugs of potential misuse.

          Drug misuse and abuse are major health problems. Harmful drugs are regulated according to classification systems that purport to relate to the harms and risks of each drug. However, the methodology and processes underlying classification systems are generally neither specified nor transparent, which reduces confidence in their accuracy and undermines health education messages. We developed and explored the feasibility of the use of a nine-category matrix of harm, with an expert delphic procedure, to assess the harms of a range of illicit drugs in an evidence-based fashion. We also included five legal drugs of misuse (alcohol, khat, solvents, alkyl nitrites, and tobacco) and one that has since been classified (ketamine) for reference. The process proved practicable, and yielded roughly similar scores and rankings of drug harm when used by two separate groups of experts. The ranking of drugs produced by our assessment of harm differed from those used by current regulatory systems. Our methodology offers a systematic framework and process that could be used by national and international regulatory bodies to assess the harm of current and future drugs of abuse.

            The association between cannabis use and depression: a systematic review and meta-analysis of longitudinal studies

            Longitudinal studies reporting the association between cannabis use and developing depression provide mixed results. The objective of this study was to establish the extent to which different patterns of use of cannabis are associated with the development of depression using meta-analysis of longitudinal studies.

              Prenatal exposure to cannabis and maternal and child health outcomes: a systematic review and meta-analysis

              Objective To assess the effects of use of cannabis during pregnancy on maternal and fetal outcomes. Data sources 7 electronic databases were searched from inception to 1 April 2014. Studies that investigated the effects of use of cannabis during pregnancy on maternal and fetal outcomes were included. Study selection Case–control studies, cross-sectional and cohort studies were included. Data extraction and synthesis Data synthesis was undertaken via systematic review and meta-analysis of available evidence. All review stages were conducted independently by 2 reviewers. Main outcomes and measures Maternal, fetal and neonatal outcomes up to 6 weeks postpartum after exposure to cannabis. Meta-analyses were conducted on variables that had 3 or more studies that measured an outcome in a consistent manner. Outcomes for which meta-analyses were conducted included: anaemia, birth weight, low birth weight, neonatal length, placement in the neonatal intensive care unit, gestational age, head circumference and preterm birth. Results 24 studies were included in the review. Results of the meta-analysis demonstrated that women who used cannabis during pregnancy had an increase in the odds of anaemia (pooled OR (pOR)=1.36: 95% CI 1.10 to 1.69) compared with women who did not use cannabis during pregnancy. Infants exposed to cannabis in utero had a decrease in birth weight (low birth weight pOR=1.77: 95% CI 1.04 to 3.01; pooled mean difference (pMD) for birth weight=109.42 g: 38.72 to 180.12) compared with infants whose mothers did not use cannabis during pregnancy. Infants exposed to cannabis in utero were also more likely to need placement in the neonatal intensive care unit compared with infants whose mothers did not use cannabis during pregnancy (pOR=2.02: 1.27 to 3.21). Conclusions and relevance Use of cannabis during pregnancy may increase adverse outcomes for women and their neonates. As use of cannabis gains social acceptance, pregnant women and their medical providers could benefit from health education on potential adverse effects of use of cannabis during pregnancy.
