Well perhaps you'll find this more interesting. "Maeng Da" (pimp class/grade) is also known as "Riau" depending on the source but for the sake of identification lets refer to it as "spiked leaf". Now as far as I know, there are only 2-3 groups specifically
exporting kratom from S.E.Asia to the entheogenic community. Now (I'm gonna be careful not to let this go too close to vender discussion) most vendors are buying from one one of two wholesalers. They have mostly the same product but different names for each so one will call the spiked leaf something else and their purchasers sometimes change the name to appear more exclusive or whatever.
The spiked leaf is more potent than average but with the "maeng da" variety cramping was unavoidable and quite painful, so I simple stopped using it. I think the cramping was the result of increased gas production and decreased motility of the g.i. tract.
I've noticed that kratom (like most opiates) slows my digestion. People don't realize that gas can be extremely painful, because they can usually fart. In fact it can be so painful that it often mistaken for a heart attack!
Now the funny thing is that spiked leaf from the other wholesaler didn't have any negative effect on my digestion.
All kratom variations will have certain properties in common and some slight differences but the maeng da that caused consistent stomach cramps also took longer to peak but didn't last as long as regular leaf. It also gave me loose stools the next morning, something that has never been an issue with kratom.
Previously a fake kratom extract appeared in headshops. It was made of O-Desmethyl Tramadol mixed with caffeine.
The funny thing is it is only the spiked leaf from a single supplier, that left me feeling bad. The spiked leaf from the other wholesalers never gave me that reaction. It is possible that the single harvest had some micro-tourists that decided to come along or that the plant material was sprayed with a fertilizer or something. Back in my poppy pod days I used to "enjoy" the stomach cramps I'd get from trying to salvage bad pods.
I think the doctors figured it was something living too based on this quote,
I did not disclose Kratom, as I knew that they had not idea what it was and they'd be quick to blame it. I wanted to get all tests first.
I was released with a 'no raw seafood' warning, since it was my last meal before this (my wife ate the exact same thing I did, and she was fine) as a testament of the doctor's absolute ignorance as to what was wrong with me.
And that guy was a dumbass. Always tell the doctors EVERYTHING you know, don't make them guess.
