Just to clear a few things up: First of all, W-15 is not really an opiod because neither the substance itself or it's metabolites shows any affinity for the opioidreceptors, although it is chemically related to opioids like fentanyl. Secondly On the other hand, this substance have a weak affinity for both the adenosine 1 receptors, and the cannabinoid 2 receptors, something which may explain some of it's analgesic effects. My point is that this substance should be moved to another category than the opioid category as it isn't really an opioid. Review by Dimethyl (Posted on 25/10/2018)
