A bill could be introduced soon requiring anyone found guilty of possessing heroin to serve at least three years behind bars.
State Representative Scott Dianda, an Upper Peninsula Democrat, is working on the measure.
He says a ton of heroin is making its way in to the U.P. from Wisconsin and he wants to put a stop to it.
Dianda hopes harsher penalties will discourage people from selling or buying heroin in Michigan.
The drug is finding its niche as a cheap substitute for prescription pain killers.
He expects to introduce the bill this fall.
