A recent Scientific American article entitled Is “Cannabis Good or Bad for Mental Health?” suggested that if you think you understand cannabis and its impact on our well-being, you probably don’t. With over 500 chemical constituents, interacting a different doses and ingested by different means, there are endless permutations of complexity for the ways cannabis can impact our emotional health. We can’t slap one label on it as either “all helpful” or “all harmful” when it comes to the impact on depression, anxiety, trauma and psychosis. Cannabis and all of the spin-off substances continue to evolve faster than rigorous science can keep up. The truth is — at the level of randomized control trials — we know very little.
