There are still a number of questions surrounding a Federal government move to legalize marijuana.
Lawyer Matt Letson says there is currently no legal parameters governing pot use in the workplace.
Letson notes some provinces, including Ontario, have taken steps to clarify the rules.
Letson notes there have been several legal cases involving employers, employees and the use of marijuana in the workplace and he says the best policy is to disclose the use to your employer.
Medical Advisor Dr. Paul Atkinson says despite being legally prescribed in some cases, Health Canada has not issued a drug identification number for cannabis like it has for other drugs or blood pressure meds.
Atkinson says those other drugs have undergone vigorous testing and have been regulated.
