P ediatric use of medical cannabis entered widespread public consciousness in 2013, when the CNN television network aired Weed, a documentary highlighting its therapeutic benefits in children with severe epilepsy. 1 Since then, pediatric medical cannabis has continued to gain societal and scientific attention. [2][3][4][5] Cannabis contains 2 main cannabinoids with proposed medicinal effects: cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC). 6 Cannabidiol reduces seizure frequency and duration in children with treatmentresistant epilepsy, 7 specifically Dravet syndrome; 8-10 THC is known to have antiemetic, appetite-stimulant and analgesic effects useful in cancer treatment. [11][12][13][14][15] We use the term medical cannabis for any combination of CBD and THC.In 2018, Canada became the second nation to legalize cannabis for both recreational and medical use. Products under pharmaceutical regulations (Controlled Drugs and Substances Act [S.C 1996, c. 19]) are available via prescription as semisynthetic drugs 16 or highly purified plant-derived drugs. 17 Nonpharmaceutical, standardized cannabis extracts are available with medical authorization from more than 150 licensed producers, (Cannabis Act [S.C. 2018, c. 16]). Additionally, adults may obtain cannabis intended for recreational use, without medical authorization, from retail stores, called dispensaries, or black market sources. 18,19 Provenance of cannabis from dispensaries is often unknown. Cannabis can also be grown at home.There is a lack of robust evidence to guide cannabis practices across pediatric medical disciplines. 2,20,21 The Canadian Paediatric Society does not support its use, except on a carefully considered, case-by-case basis, citing limited evidence and potential harms. 2 Thus, in Canada, use of medical cannabis is most known in children with severe conditions.

While improvements in care quality were only seen in two areas, our approach was highly effective in achieving knowledge dissemination, knowledge improvement, and practice change goals.
