Challenges remain in clinical research of medical cannabis. However, increasing anecdotal and clinical study reports of potential benefit, advances in understanding of the endocannabinoid signaling system, and growing public acceptance for the use of cannabis in carefully selected patients upon the advice of their physicians, is driving renewed and significant interest among researchers. Scientists are working to confirm the existence of other cannabinoid receptors and to study the therapeutic potential of over 80 medically significant cannabis compounds. This work could reveal a wide range of potential therapeutic uses for cannabis, from those impacting the CNS, like Attention Deficit Hyperactivity Disorder (ADHD), to inflammatory and autoimmune diseases like Crohn’s disease.
As is the case with all attempts to provide medicines to patients needing them, the focus is on moving the science of medical cannabis forward and making treatments available to those who will derive benefit while first doing ‘no harm.’
