R. v. Adams

R. v. Adams

The Crown proved beyond a reasonable doubt that Adams operated a conveyance while impaired by a narcotic analgesic because (1) consistent eyewitness and police observations established erratic driving and impaired behaviour; (2) a certified DRE concluded impairment by a narcotic analgesic following the 12‑step evaluation; (3) forensic toxicology detected hydromorphone, oxymorphone and a clonazepam metabolite in the accused’s urine; and (4) the legislative presumption in s.320.31(6) supports causation; mens rea was satisfied by voluntary consumption with knowledge of warnings; conviction entered.
