Polish police have closed down the largest amphetamine factory ever discovered in Poland and seized nearly 20 kilograms of high quality amphetamine with a street value of around 600,000 zlotys (NZ$230,000).
Poland is a major producer of amphetamine and while other narcotics such as cocaine tend to be imported, amphetamine is produced locally both for domestic consumption and export, according to police.
Police said they stormed the premises in the Czosnow municipality near Warsaw and arrested two men at the factory which housed a sophisticated chemical laboratory.
The unassuming property, painted white and resembling a farm, may have produced as much as 500 kilograms of the narcotic this year alone, police said.
"This was pure amphetamine of a very high quality," said Warsaw Police spokesman Mariusz Mrozek. He said amphetamine was now seen as a Polish "national product" in the drugs world and that homegrown chemists were "specialists" in its production.
Police also discovered around 1000 litres of phenylacetone, a raw material used in the production of amphetamine. Such a quantity can yield around 700 kilograms of pure amphetamine worth around 21 million zlotys, they said.
