An advisory council to Ontario's health ministry is recommending that pharmacists in the province also be allowed to write prescriptions for smoking-cessation drugs. The recommendation is contained in a broader report that supports expanding the power of pharmacists to prescribe drugs for minor ailments, as well as to alter prescriptions or change dosages.

While Ontario's Health Professions Regulatory Advisory Council admits that nicotine addiction is not a "minor ailment," it says pharmacists in the province should be able to write prescriptions for stop-smoking drugs as a way to improve access for those who want to quit. ...more
