The measure includes mandatory jail time for people who make meth around children or in buildings where other people will be endangered.
It also toughens penalties for storing meth ingredients and for stealing the fertilizer used to make meth.
Attorney Gen. Lisa Madigan pushed for the bill. She says meth is different from most drugs because it is often made here in Illinois, not imported from other places.
Meth production and use is growing more common, especially in rural areas.
The legislation passed unanimously and now moves to the Illinois House.
