The safety profile of cannabis is largely unknown. The states and localities that have legalized marijuana have focused on the quality of marijuana products, but haven't required anyone to systematically report side effects. That needs to change. Since today's marijuana products are four to five times more potent than past products, old data understates the safety issues. I fear that the marijuana story is a slow-moving train wreck. We're witnessing widespread use of largely unregulated and untested products which may be toxic in themselves as well as adulterated or counterfeited.
