Calvin klein (CK) designer cocktail, new "Speedball" is the "grimm reaper": Brain dopaminergic surge a potential death sentence.

On June 18th the world lost a fabulous 17-year-old violinist prodigy a Carnegie Hall sensation, Katya Tsukanova, due to a fatal overdose of the designer drug named Calvin Klein (CK). The CK drug is so named because it contains a combination of both cocaine and ketamine. It is therefore appropriately categorized as a “polydrug.” CK (sometimes called CK1 or cable) has become a real party drug not only in England but also in other parts of the world including New York’s nightclub scenes. The feeling experienced from using CK is akin to that induced by the famous sex-inked, Molly, in the 60s and 70s. People taking this drug, mostly by snorting it, suggest that the mixture of the two-produce powerful euphoric highs coupled with a hallucinogenic feeling caused by ecstasy.
