Yes. I got severely nauseous and threw up from it, and that is despite carrying a heavy opioid tolerance, so I believe it is a unique thing for the Kratom plant. The effects were crappy as well. It seemed to have dose ceiling of the equivalent of 20mg Hydrocodone or so. Just plain not worth the money.
I tried 2 grams of a 10x extract for the first time earlier this week. VERY enjoyable experience that lasted about 90 minutes (coming from someone with next to no opiate experience so I don't have much to compare it to), although I did have a bit of a hangover the next day until mid afternoon.
i enjoy kratom very much its a pleasent mild opioid like high, its not going to give you the rush real opiates do though... and you can purchase it from online vendors just becareful where you purchase from as alot of online vendors will sell you bull shit ....extrated kratom is the way to go so you dont have to consume s much.....also if you have a herb shop or a kava bar in your location they tend to sell it there aswell some good online vedors i use are iamshaman.com and bouncingbearbotanicals.com
yeah thats pretty much exactly what the effects are, chilled out mellow body high, very similar to an opiate high just not as intense and dosent give you that initial rush
Kratom is a good product if you find the purest source. Maeng Da or Thai Kratom is the strongest NATURAL kratom.
