Drug info - quality of cocaine in different countries

[Nargyle]

Ok, so the alien that abducted me the other night told me a little story.
He said that he was a 25 year old peruvian guy who had enjoyed cocaine quite a bit in his home country, however last year he decided to travel through europe for a while, he stayed several months in the netherlands where his family originally comes from and where he still has family and friends, while there he tried cocaine a couple of times but he never got the good effects he got from peruvian coke, he just felt speedy and anxious. Then he went to visit his brother that lives in Spain, in the canary islands to be more precise, and also tried cocaine there without getting good effects again.
He says he now wonders if peruvian cocaine is much better than the coke from other countries, can anybody that has travelled or knows about this confirm his suspicions?
Thanks.
