Pot-smoking Mountie Ron Francis facing 3 more charges

A New Brunswick Mountie who made headlines for smoking medical marijuana while in uniform is facing three new charges.

Cpl. Ron Francis pleaded not guilty on Friday in Fredericton provincial court to two counts of assaulting fellow officers on Jan. 12 and breaching an undertaking to not possess or consume alcohol and non-prescription drugs.

A trial has been scheduled for July 15.

Francis previously pleaded not guilty to assaulting two fellow officers and one count of resisting arrest, stemming from an alleged confrontation with fellow RCMP officers and Fredericton police officers who arrested him on Dec. 6.

He is scheduled to stand trial on those charges on Sept. 3.

Francis, who is a member of the Maliseet First Nation, arrived at court on Friday carrying a ceremonial feather.

T. J. Burke, his lawyer, asked for a hearing on whether the court order to surrender his firearms includes his possession of a crossbow.

Burke said he may argue a Constitutional challenge based on Francis' aboriginal right to hunt.

Francis, who has a prescription for medical grade marijuana to treat his work-induced post-traumatic stress disorder (PTSD), had publicly argued he should be able to smoke the drug in uniform.

The 21-year veteran of the RCMP was stripped of his uniform and placed on medical leave in November after smoking medical marijuana on video while wearing his red serge.

Francis, who served the RCMP's J Division in Fredericton, was previously found fit to stand trial following a 30-day psychiatric assessment.
