BILLINGS, Mont. -

An 18-year-old Billings man faces seven felony charges after police say he inhaled dust cleaner and passed out while driving, crashing into another vehicle.

Darien Cordell Martin pleaded not guilty Tuesday to six felony counts of criminal endangerment and one felony and three misdemeanor counts of negligent vehicular assault. Prosecutors say one of his passengers was seriously injured.
    
Charging documents say Martin had four passengers in his car in July when he passed out after huffing Dust Off. The car crossed several lanes of traffic, went over the landscaping in front of a business and hit a car stopped at a traffic light.
    
Prosecutors say a blood test showed Martin had the active chemical substance in the dust cleaner in his system along with marijuana and opiates.
