Louis Theroux's Next BBC Documentary Sounds Pretty Harrowing

He goes to a city where even newborns are dependent on heroin

Louis Theroux's new series on the "most dysfunctional and disturbing aspects of American society" is dropping next month and his first stop is West Virginia - a city so devastated by heroin use that one in 10 babies are born dependent on the drug.

The BBC2 series will feature 3 "hard-hitting" documentaries on drugs and sex trafficking. The first episode 'Louis Theroux: Dark States - Heroin Town' looks at how a national love affair with prescription painkillers turned into a heroin crisis.

It's said around 2 million Americans are addicted to opiates, but a recent crackdown on over-prescription means they have become increasingly hard, not to mention expensive, to get a hold off.

So Americans have been turning to a cheaper and stronger opiate - like heroin - and for the first time in over two decades life expectancy in the country is declining due to the rise in fatal overdoses.

It's not the first time Theroux has delved into drug use in the States, as he ventured to California in 2009 to see how Meth had ravaged the state in 'Louis Theroux: The City Addicted To Crystal Meth'.

Louis Theroux: Dark States - Heroin Town will air 8 October on BBC2 at 9pm.
