This is different. There’s the plant. Contains about 1.5% mitragynine.

Then there were purified extracts of the active alkaloids in the plant. Started around 30% mitragynine years ago now in the 85% range.

Then there were synthetic derivatives of mitragynine (7oh, mgm-15, etc.). These are much more fun/addictive and surprisingly safe. Almost all “overdoses” involved a mix of alcohol or other drugs. Much safer than fentanyl or traditional opioids because it doesn’t meaningfully trigger respiratory depression leading to asphyxiation. Unfortunately, they’re also addictive. The harm level, imho, was somewhere around alcohol or nicotine.

I used to order it online in like 2005. Crude extracts were available maybe since 2007. The plant almost got banned several years ago. Then over the last few years all these extracts and derivatives have been coming out. MGM-15 is stronger than heroin from what I've heard. Strongest stuff I ever tried was a mitragynine gummy and it felt like hydrocodone. That one gummy had the effects of what I used to get from a couple cups of tea. Good stuff but not risking addiction to try it again. Made me nauseous too
