Most people don't know that peyote is completely legal in Canada, as it has always been. Although mescaline, peyote’s main psychoactive ingredient, is banned as a Schedule 2 drug, Canada’s Controlled Drugs and Substances Act specifically exempts peyote (Lophophora).
This disparity came about in the mid 70’s, when Canada was about to sign the international Convention on Psychotropic Substances. That convention insisted that mescaline be “controlled,” and that the easiest way to do that would be to ban peyote.
Although peyote does not grow naturally in Canada, native tribes in Alberta and Saskatchewan had been importing peyote buttons from Arizona and other arid locales in the American Southwest, and using them in peyote ceremonies, for at least a few hundred years. Some believe peyote has been imported into Canada for thousands of years.
Federal officials were surprisingly sympathetic to the peyotists’ plea not to ban their sacred plant, and so decided to only ban the extracted active ingredient, mescaline.
So yes you can grow it eat it make tea just don't extract the mescaline. To bad the native did not do more psychedelic maybe all be legal lol...
Happy tripping all and be safe .
