Customer Care Assistant and Production Assistant Marsha McKenna grooms marijuana plant clones at Tweed Marijuana Inc in Smith's Falls, Ontario, February 20, 2014.

Tweed Marijuana Inc, which converted an old chocolate factory into a marijuana farm, led the pack by becoming the first publicly held Canadian company in the sector. Picture taken February 20, 2014.
