People with diabetes in Colorado won’t have pay more than $100 a month for insulin under a new law.

Gov. Jared Polis signed  legislation Wednesday that caps insurance co-payments on insulin no matter the type of insulin.

KCNC-TV reported that the Democrat declared that the days of insulin price gauging are over in Colorado at a ceremony filled with people affected by diabetes.

The bill was sponsored by state Rep. Dylan Roberts, D-Avon, who lose his brother, Murphy, to diabetes.

Nationally the average insulin price nearly tripled from 2002 through 2013, and prices have risen 10% or more a year since then, forcing many diabetics to ration their insulin.

Some have ended up in hospitals and a few have died as a result, which has led to congressional hearings on the issue.
