DAYTON (AP) — The Ohio State Highway Patrol has reported more drug-related arrests and seizures in Ohio in the first half of this year compared with the first six months of 2012.

Recently released patrol statistics show troopers made 4,728 drug arrests January through June for an 18 percent increase over the same period last year. The Dayton Daily News reports that is a rise of 42 percent compared to the average number of arrests from 2010 through 2012.

Seizures of prescription pill stimulants, depressants and hallucinogens also rose substantially the first half of the year over the three-year average. Total heroin arrests rose 100 percent compared with the 2010-2012 average.

Patrol Lt. Anne Ralston says the increased arrests and seizures stem from greater drug trafficking and stronger efforts to stop it.
