HELENA, Mont. (AP) - A state representative from Missoula is introducing a bill to revise Montana's DUI law to account for people driving under the influence of marijuana.

Republican Rep. Doc Moore says his House Bill 168 provides a legal limit for the amount of THC - the active ingredient in marijuana - that can be in a person's blood while they're operating a motor vehicle.

Moore plans to introduce his bill in the House Judiciary Committee on Thursday morning.
