An Indian man in Pittsburgh has pleaded guilty to selling powder that dilutes heroin and tiny "stamp" bags used to package it for street sale, and agreed to be deported.
That won't happen until 72-year-old Akhil Mishra returns for sentencing in August.
He was previously convicted in 1992 and 2000 of selling marijuana bongs and drug paraphernalia at "head shops" his family formerly owned in Pittsburgh.
Federal prosecutors cracked down on Mr Mishra again last year in the midst of a heroin overdose epidemic in western Pennsylvania.
Mr Mishra's defense attorney George Bills said his client expects to be sentenced to the jail time he will have served since last year.
Authorities contend Mr Mishra continued selling the items out of his Indiana Township home even after they raided his business.
