'Return to Amish' Star Charged for Meth

"Return to Amish" star Chapel Peace was peddling more than butter and blankets ... prosecutors say she was deep into meth.

The 33-year-old was one of 27 busted in Pennsylvania this week during a massive drug sting. According to the State Attorney General, detectives seized more than $90k of meth, $8,400 of heroin and more than $27k in cash.

Peace, who's been featured on the series, was charged with possession with intent to distribute and for having paraphernalia. Chapel was also reportedly arrested last year with heroin.

No word if this will affect Peace's gig on the TLC show.
