I'm also quite skeptical, but if this actually is accurate, I don't think the potential for a mechanism of action is necessarily that far-fetched. My heart rate absolutely increases to some degree for an extended period of time when I consume sativa cannabis, for example, and I don't think this is uncommon. Changes in heart rate could potentially alter aspects of the heart, over a sufficient length of time.

Even if that weren't the case, cannabis contains lots of psychoactive compounds which aren't fully understood, and even for the ones we do seem to understand, the brain and body are incredibly complex and chaotic systems and could possibly exhibit unexpected effects when exposed to them.
