On the next episode of the reality show, viewers will meet two young women with very different obsessions.
First there's Shannon, a 20-year-old who just can't seem to stop drinking gasoline.
"My favorite way of drinking the gasoline is through the gas can or the jerrycan," Shannon explained. "I take the cap off and I breathe in the fumes that come forcing out of the can. Sometimes, if there's any gas on the lid, I'll lick it off."
The dangerous drink isn't a rare treat for Shannon. She consumes 12 teaspoons of gasoline a day. That's a total of over 5 gallons in over the course of the last year.
Also featured on the upcoming episode is Lacey, a 24-year-old who's carried around (and sniffed) a doll head since she was 4.
"It kind of smells like marshmallows," she said of Suzi-Q -- that's the doll head's name. "It's like aromatherapy."
Learn more about Shannon and Lacey and whether or not they're able to kick their habits when "My Strange Addiction" airs Sunday night at 10 p.m. ET on TLC.
