I think I know. Symptoms sound familiar. I don't want to scare you unnecessarily, but this could be a serious problem, I think it's a levamisole (it accounts for the speedy sensation) cut in which case you ought to stay the hell away from it unless you can get it washed properly. It's time to do some serious googling now.Google levamisole and cocaine or go to erowid, there are a lot of good articles on the subject online.https://www.erowid.org/chemicals/cocaine/cocaine_article2.shtmlA lot of the lab tests can't distinguish between levamisole and cocaine. Dancesafe were working on a kit, but I'm not sure it's available.The real problem is that levamisole isn't being added at the street level, it's being done right at the origin of the cocaine; the farmers in Columbia. So the entire supply chain is infected. If I were to hazard a guess, I'd say the DEA's death squads in South America have influenced production either directly or indirectly. The cocaine could be cleaned up in Spain before it reaches the UK, but there's no incentive to make that happen. There is also the possibility that this is a psy-ops operation, either completely or in part. I have a feeling this is not the case though. There is one way to find out. Get your cocaine tested with one of the new levamisole detection drug kits and see what it says.
