More than 15 kilograms of so-called "superbuff" cocaine has been seized from a house in Airdrie.

Superbuff is cocaine that has been cut with another substance, in this case Phenacetin — a common cutting agent dealers use to dilute the purity of cocaine in order to maximize profits.

Phenacetin is a pain killer that was withdrawn from the Canadian market in 1973 after it was associated with cancer and kidney damage. 

The seizure was co-ordinated by the Alberta Law Enforcement Response Team (ALERT), which says the bust highlights the dangers for drug users and the unknown chemical substances added to drugs.

“For the recreational drug user this should be a wake-up call as the idea of pure cocaine is a myth," said Sgt. Glenn Uchytil, a CPS member seconded to ALERT, in a release.

"You may have just wanted to get high, but as we saw last year with some tainted ecstasy, you may wind up dead."

Police also found $100,000 worth of cocaine.

The seizure followed a two-month ALERT investigation that began after a tip came in about someone distributing cocaine to dial-a-dope drug traffickers.

Two people have been arrested and a warrant has been issued for a third.
