“To summarize the history and evolution of cannabis use and policies and to review current therapeutic uses, safety, and the central role pharmacists can play.
Cannabis regulation and use have evolved over the centuries and are becoming more widely accepted, with over two-thirds of states in the United States having an approved cannabis program. However, changing policy and a paucity of controlled clinical trials has led to questions on the safety and effectiveness of cannabinoid therapies. Although there are conditions for which cannabinoids may be helpful, potential contraindications, adverse effects, and drug-drug interactions should be taken into account.
Pharmacists are in a unique position based on their accessibility, knowledge, and skills to guide product selection, dosing, and discuss drug interactions and adverse effects to educate patients on safe cannabis use, whether it be delta-9-tetrahydrocannabinol, cannabidiol, or a combination thereof. Pharmacists and pharmacy organizations, moreover, should advocate for an integral role in the medical cannabis movement to ensure patient safety and evaluate cannabinoid pharmacology, pharmacokinetics, drug-drug interactions, safety, and efficacy through rigorous investigations.”
