The Maine House has backed a bill that would require drug manufacturers to institute a system to collect unused prescription drugs from the public.

The bill, LD 821, “An Act to Support Collection and Proper Disposal of Unwanted Drugs,” was approved 91-51 in the House on March 17. The state Senate has yet to vote on the measure.

The bill would require the manufacturers to pay for the cost of the program without the cost being shifted to consumers.

Local legislators who voted for the bill were Democratic Reps. Chuck Kruger of Thomaston; Edward Mazurek of Rockland; Joan Welsh of Rockport; Andrew O’Brien of Lincolnville; House Speaker Hannah Pingree of North Haven; Wendy Pieh of Bremen; Elizabeth Miller of Somerville; Veronica Magnan of Stockton Springs; and John Piotti of Unity.

Voting against the bill were Republican Reps. Wes Richardson of Warren, Jayne Crosby Giles of Belfast; Jonathan McKane of Newcastle, and Michael Thibodeau of Winterport.
