Please note that two reviewer comments relating to the article by Yao et al., Cannabis Use Prevalence and Correlates in Patients Attending a Canadian Cognitive Clinic ^{Reference Yao, Maxwell, Ismail, Williams, Fischer and Hogan1} were inadvertently omitted from this issue and are therefore not included in this Table of Contents. The comments^{Reference Di Ciano2,Reference Troup3} have been correctly linked to this article and are available on Cambridge Core. They have also now been assigned to the July issue (volume 53, issue 4) and are listed in its Table of Contents. The Journal apologises for any inconvenience this may have caused.
