(Washington, DC)  --  Pot stocks are soaring sky high after the firing of Attorney General Jeff Sessions.  Shares of Canadian marijuana company Tilray went up 30-percent after news that Sessions was out.  Other publicly traded pot companies such as Canopy Growth and Aurora Cannabis also had their stocks lifted more than eight percent.  Sessions had promised to roll back Obama-era policies that allowed states to set their own rules on weed.  Marijuana companies were also enjoying a boost because Michigan voters approved a measure legalizing recreational pot.
