RESUMEN
BACKGROUND: Chronic pain is a major health issue, adversely affecting millions of Australians and costing billions of dollars annually. Current pharmaceutical treatments may be limiting, and in some cases ineffective, while carrying substantial liabilities. Medicinal cannabis is an increasingly popular, albeit controversial, alternative. OBJECTIVE: The aim of this article is to briefly review the scientific evidence related to medicinal cannabis for the treatment of chronic pain and update physicians on relevant issues and optimal prescribing practices. DISCUSSION: To date, >130,000 medicinal cannabis approvals have been issued in Australia, mostly by general practitioners, with approximately 65% of these to treat chronic non-cancer pain. Available products deliver Δ9-tetrahydrocannabinol (THC) and/or cannabidiol (CBD). Despite robust supportive data from animal models, current clinical trial evidence for THC and CBD efficacy in chronic pain is incomplete. In their prescribing decisions, doctors must balance patient demand and curiosity with caution regarding potential risks and limited efficacy.

The observation that marijuana reduces intraocular pressure was made by Hepler and Frank in the 1970s. Since then, there has been a significant body of work investigating cannabinoids for their potential use as therapeutics. To date, no endocannabinoid system (ECS)-modulating drug has been approved for clinical use in the eye; however, recent advances in our understanding of the ECS, as well as new pharmacological tools, has renewed interest in the development of ocular ECS-based therapeutics. This review summarizes the current state-of-affairs for the use of ECS-modulating drugs for the treatment of glaucoma and ocular inflammatory and ischemic disease.
