The Vancouver Sun reports in its Monday edition that strong interest in marijuana among older B.C. residents has them packing into information sessions at seniors centres to learn more about the newly legalized drug. The Sun's Matt Robinson writes that Terry Roycroft, the head of Vancouver's Medical Cannabis Resource Centre, a private organization that provides guidance on medical use of cannabis, has been speaking to seniors for several years about marijuana. Now he is seeing care homes and seniors centres pro-actively reaching out and requesting information sessions. Mr. Roycroft is now partway through a series of such talks across the province. "A lot of these seniors went through the flower power, the sixties, and so they're familiar kind of with cannabis. But only in the old forms, the weak products that were available back then," he said. Mr. Roycroft talks about the differences between tetrahydrocannabinol (THC) and cannabidiol (CBD), the effects of indica versus sativa, and the benefits of delivery methods like smoking, vaping and ingesting. (Unlike THC, cannabinoids like CBD will not get you high.) There are also considerations around possible interactions between cannabinoids and prescription drugs.
