Do you mean the one where they mixed in a synthetic opioid (tramadol i think)?
No I wasn't talking about that. Although I mentioned kratom and ODT at the same time, I was referring to both substances as separate entities, where the same thing happened to both of them, with them subjectively having less enjoyable experiences in later batches. I had forgotten about the kratom mixed with ODT batches.
Although 4DQSAR has already explained about certain batches of kratom that had ODT mixed into them during the RC era, they were called Krypton, and caused several deaths in Sweden. Which presumably is where those batches were most widely available. I never saw Krypton kratom for sale anywhere in the UK, or anywhere that shipped to the UK.
Following on from these deaths, the authorities in the UK were unable to differentiate between those adulterated batches, and unadulaterated batches, and ended up placing a ban, or heavy restrictions on kratom in the UK. Where it's now illegal to sell and import the stuff. But weirdly it doesnt seem to be illegal to posess. According to wikiepedia anyway. I don't think buying it within the country is illegal either. The information about it's legal status in the UK is worded very strangely.
I was talking about the 100% pure kratom (with no additives) that was available during the RC era. The stuff from one particular supplier was fantastic in my experience.
My mood, sociability, confidence, energy, wellbeing, and musical appreciation, all suddenly went to 11 out of 10. It was amazing stuff.
As you've seen above, some others did not rate it, but many did, and it had many devotees.
For unknown reasons, today's stuff, even though it is genuine kratom, is just not very good. It's main function for me these days is to provide a pleasant and significant energy boost (it's closely related to coffee) which it is effective at doing. Todays kratom doesnt do any of the amazing stuff that the 2010s stuff did for me. I dunno if the grows just arent as good, or there's something been fucked up with the genetics or conditions of the crops being grown, but they are definitely lacking the magic of the best stuff. I don't think it's my brain chemistry having changed. I think it's the product itself. Many other people say the same things about current supplies that are easily available in the UK from a certain clearnet vendor. Who shall remain nameless.
I suspect the same thing that's happened to kratom has happened to mephedrone, in terms of it just not being anywhere near as good as it was previously.
I tried many times post ban to acquire what was advertised as pre-ban quality and experience. But it never was. I eventually gave up after probably 5 or 6 attempts from various different suppliers, all saying the same thing.
I doubt if things are any different today. But I may try one more time. I've seen a photo of some product online that certainly looks like pre-ban did. But of course the actual product may not be what is in the photo, and even if it is, I doubt if the effects will be the same as pre-ban.
