Stambler was convicted of providing prescriptions for hundreds of oxycodone pills for patients who had no legitimate medical need for the painkillers.
The sentencing follows last week's manslaughter conviction of a New York doctor in an overdose death.
Dr. Stan Li also was convicted of selling prescriptions to David Laffer. He is serving a life term after pleading guilty to killing four people during the pharmacy robbery for painkillers in June 2011.
