When Hershey's had a plant in Smiths Falls, Ontario, you could smell chocolate from miles away. But not a single chocolate bar has rolled off the line since the plant closed in 2008. Now, Smiths Falls, a working class town of about 10,000 in Eastern Ontario, has a new industry, medical marijuana. Health Canada is changing its medical marijuana rules, and Tweed, a licensed marijuana production company, has just received its license to grow medical cannabis there. Some are hoping the new plant will bring much needed jobs to an area that's had it tough for the last few years.
