While writing up case reports regarding synthetic cannabinoid-associated deaths and reading other reports, this thought occurred...
Synthetic cannabinoid receptor agonists (especially newer generation compounds from 2013+) are a diverse chemical grab bag o' "fun".
Fun is defined here as adverse effects including tachycardia, seizure, nephrotoxicity, and death.
If you choose to partake in the substances, then keep that in mind. And no, I do not recommend or condone using synthetic cannabinoid containing products, so don't ask me what substances I would recommend using (seriously I get those kinds of questions).
