In January 2026, Health Canada published a new plain language document with evidence-based information on how to choose and use a cannabis product for medical purposes. The resource, Information on the Use of Cannabis for Medical Purposes, is designed to support patients in making informed decisions about lower-risk use of cannabis, and to help health care providers in discussions with patients about cannabis use for medical purposes. To date, Health Canada hasn’t authorized the use of cannabis products to treat any specific diseases or symptoms. However, the available research, although limited, suggests that cannabis might relieve chronic non-cancer pain (mainly neuropathic), insomnia and depressed mood associated with chronic diseases. There currently isn’t enough evidence for Health Canada to recommend which cannabis product to take for any specific health condition. Cannabis Use for Medical Purposes See: bit.ly/47wLgkR A new World Health Organization (WHO) guideline provides evidence-based recommendations for the safe and effective use of mercury free dental materials and minimal interventions to prevent and manage dental caries, in alignment with the Minamata Convention on Mercury and global oral health priorities. The resource, WHO guideline on environmentally friendly and less invasive oral health care for preventing and managing dental caries, evaluates the clinical effectiveness, cost effectiveness, toxicity and environmental impact of fluoride varnish, silver diamine fluoride (SDF), pit and fissure sealants, glass ionomer cements, resin-based composites and related materials. The document incorporates GRADE based assessments and guiding principles, including prevention first, minimally invasive care, shared decision making and the precautionary principle, alongside risk mitigation advice for vulnerable groups and occupational safety measures. It also outlines implementation strategies, sustainability considerations and research gaps to support countries in transitioning toward mercury free, environmentally responsible oral health care.
