Yesterday, it was announced that teen violin prodigy Katya Tsukanova was the latest casualty of the so-called ‘Calvin Klein’ drug craze.

The 17-year-old was found dead by her Russian billionaire father at their mansion in Kensington on June 18, with the cause of death suspected to be an overdose.

Father Igor Tsukanova told The Telehraph that his daughter ‘had a bright future’, adding ‘she was such a smart girl, and she made one bad choice’.


The drug cocktail, known as Calvin Klein or CK Blend, has been reported to be sweeping the London nightlife scene, with friends of the tragic youngster saying ‘it’s everywhere’.



But what is this deadly drug craze, and what are the potential health implications for those who take CK?

The nickname CK (or Calvin Klein) comes from the first letters of the drugs the cocktail contains; Cocaine and ketamine.

It is sometimes called CK1 or cable too, and is considered to come under the umbrella of ‘poly drug use’, which is when two different psychoactives are taken to achieve a desired effect.

According to some reports, snorting the two mixed or one of the other produces a euphoric feeling similar to ecstasy, as one is a stimulant and one is a hallucinogenic.

Although both of these drugs can be dangerous on their own, the different reactions the body has to both of them mixed can be even worse. Ketamine.com, who warn about the dangers of the substance (which is commonly used by vets on horses) have warned that it can be ‘life-threatening’ and has a ‘high risk of addiction for both drugs’.

They also warn that there is the potential for violent behaviours, bad trips, and bingeing as tolerance increases.

One study in the International Journal of Toxicology also states the mix ‘has been associated with increased risk of human immunodeficiency virus (HIV)’, although doesn’t explain how this is the case.

Both drugs carry different dangers including heart problems, bladder problems, abdominal pain, and high blood pressure. Of course, there is also the risk of overdose when taking any drug.

Drugs charity Frank claim ‘the risk of overdose increases if you mix cocaine with other drugs or alcohol’ and ‘taking ketamine can be fatal, particularly if it is mixed with other drugs’.
