For anyone who may be struggling with chronic pain and/or opioid addiction, I implore you to research kratom. As far as anyone can tell, it is safe, minimally addictive, and in my experience it is good for head pain, stomach pain, anxiety, minor depression, not to mention potentiation of all kinds of other drugs.

Of course, use at your own risk. It may interact dangerously with many compounds, because it inhibits the cytochrome p450 enzyme. That said, after a six month up to three times a day habit, I've quit cold turkey twice without too much trouble.

I recommend I highly if you're out of other options.

One last warning, do not buy in person, you will be ripped off. You can get 250g for less than $30 online, and a dose for pain is 1-2 grams. Higher doses are mildly psychoactive, but OD is anecdotally impossible because you quickly become nauseaus and throw the powder up if you take in excess of 8-10+grams.
