K@ is a partial agonist. I can give you a reference if you want some reading material as I know you're of the scientific persuasion. It's also not a very biased ligand. It has somewhat similar affinity for the kappa-opioid receptor which has sort of an opposing effect to mu-opioid agonists. That's probably partly why it's much less addictive than many other opioids. It also doesn't have many of the off-target toxicities associated with mu-opioid agonists.As you know I am agreement with you that K@ should not be sold in kava bars. I pretty much agree with 99% of what you say here... However, I think maybe you are exaggerating the dangers of K@ a little. It is true that it is an opioid, meaning it is an opiate receptor agonist (a full agonist as a matter of fact). But, there is some evidence that (for reasons I don't really understand) it has less addictive potential than other drugs in that category, and that the withdrawals are often less severe. It is true that people get addicted to it, and some people do have withdrawal symptoms. But the appeal of it--and the reason I believe it should be legal, whereas harder things should not--is that it seems to be milder and less harmful than stronger drugs on that continuum. At one point you say an overdose of K@ could possibly be fatal, but I'm not sure if that is true. Opiates like heroin are notorious for overdose deaths, of course, but as far as I know a K@ overdose probably won't kill anyone. A krat overdose will cause very unpleasant symptoms such as nausea, vomiting, etc. but is very unlikely to be fatal. Of course your point was the danger that people will confuse kava with K@ and take too high a dose: and I'm 100% with you on the need to educate people about that. (I'm reminded of a certain scene in the movie Pulp Fiction where a character confuses one substance for another...)
It's also not entirely correct to call the plant an opioid because it has alkaloids that bind opioid receptors. Many many organisms contain opioids, but that doesn't make the organisms opioids. However, K@ preparations have some comparable activity to opioids, so it's not far fetched to call it an opioid.
I'm honestly tired of the K@ discussions (more like bashing). Isn't it against the rules anyways??
