I know a lot of addicts who have used Kratom to quit opioids. It's pretty much the only thing I've ever seen people have LONG TERM success with. Withdrawal is fucking brutal from these drugs, that's why they are the gold standard of addiction. Hell, opioids are the first drugs that pretty much all humans are exposed to...due to the casomorphin in a mother's breast milk (nature's way to calm a grouchy, hungry baby.)
I don't judge addicts. It's completely understandable how someone who is prescribed pills for legit pain could become a heroin junkie...and some people are especially predisposed to that weakness. And then there is long term post-acute withdrawal. With Kratom, they can stop hard opiods cold turkey and gradually reduce the K dose to cessation. They will still withdraw from the Kratom, but it lasts a few days and then it's over. It's nothing compared to heroin withdrawal...nothing.
If they ever feel the need to relapse back to hard opiods, then having K on standby gives them something to take that craving away on the spot. The stuff is about $45/lb if you know where to look and depending on your state laws, it is completely legal. The pharmaceutical companies absolutely want to ban the stuff and they are dumping millions in to lobbying for that ban. It cuts in to their profits for chronic pain management...and it's an entire world of difference in how safe it is compared to the poison that they peddle. The worst part is, it helps people to stop being dependent on their product....taking their power away. It also works wonders for alcoholics who want to quit drinking.
I'm partial to the white vein maeng da strain.
