Well shit, take some then, lol. Also, please don't call it "herbal heroin". While it does contain alkaloids that are opioid reptor agonists so you coul refer to it as an opioid, it is nowhere near being in the same league as heroin. If anything, poppy pods would be herbal heroin as they actually contain morphine, which is pretty damn close to diacetylmorphine(heroin), and is in fact the source of the morphine which people synthesize into heroin.
Do you not know how to take kratom? There are plenty of descriptions of how online. It's easier with powder, you don't have to brew a tea like you do with leaves.
