To date it has featured people obsessed with everything from teddy bears to hair dryers and season three features some of the most bizarre subjects yet.
Taking centre stage in the third season is 28-year-old Jaye from Houston, Texas who can’t get enough baby powder.
She describes that friends were convinced that she had a secret drug habit when they visited her house and saw every surfacecoated with a thin layer of white dust.
Without her daily fix she states, ‘I wouldn’t be able to function.’
According to Jaye her addiction started when she accidentally spilled powder as a youngster and inhaled it by mistake.
And over the past sixteen years her addiction has spiralled out of control.
Now, not content with merely sniffing the powder, Jaye actually places the substance in her nostrils up to ten times a day using a tablespoon.
She estimates that she has snorted 1,125 pounds – around half a ton – of powder since her obsession began.
It is widely known that inhaling talcum can cause aspiration pneumonia which come from breathing in a foreign substances – a condition that can damage the airways.
And those around her air their concerns during the documentary.
Friend Larry confronts Jaye about her addiction when she returns from the shops with yet more supplies of talc.
‘What do you mean you’re running low on baby powder? You don’t have any children.
‘And you yourself don’t think of this as a health issue?,’ he says.
Jaye insists that her peculiar addiction is not a problem and to date she hasn’t encountered any side effects.
She now can’t go an hour without smelling the scent.
‘I find it irresistible and it’s hard for me to stay away from it for long periods of time,’ she said. ‘I always keep a stash somewhere so I can get a smell.’
Meanwhile Nathaniel, 27, from Arkansas, describes how he has been in an intimate relationship with his car for nearly five years.
He reveals that he goes on dates with Chase, a 1998 Chevy Monte Carlo, buys it birthday gifts, and even has sex with it. ‘[I’m attracted] emotionally and sexual. It is hard to explain.
‘It’s just something I’ve had for quite a long time and I know he doesn’t return the favors like I give to him as far as working on him.
