Some interesting bedtime reading
Herkinorin looks very interesting indeed. Beta-arrestin 2 Doesn't appear to be the only mechanism in play in terms of opioid tolerance, conditioned place preference, dependence liability, there are other factors, such as cholestocystokinin receptors, ORL-1 (the nociceptin opioid-like receptorddddddddddddddddddddddddddddddddddddddd
