The new system, known as the Marihuana for Medical Purposes Regulations, will "provide access to quality-controlled marihuana for medical purposes, produced under secure and sanitary conditions, to those Canadians who need it," said the government's health agency, Health Canada, which announced the plans in June.
It will be a huge change for medicinal weed in Canada.
Until now, medical pot has been produced only by individual growers, who are not allowed to supply more than two people each. Starting this April, those small-time growers will have their licenses nullified, and large, privately owned weed farms (including a former Hershey factory in Ontario) will replace them.
