There is some great information on the CMA site.
Recommending a public health approach
In legalizing cannabis, the federal government must focus on protecting Canadians and reducing any potential impact on health — in particular for children and youth.
In its submission to the federal Task Force on Cannabis Legalization and Regulation, the CMA recommends a broad public health approach that would focus on:
preventing drug dependence and addiction;
increasing availability of assessment, counselling and treatment services for those who wish to stop using; and
increasing the safety for those who are using through harm reduction programs and awareness.
They have posters and other links you can check out as well.
