Police patrolled roads leading in and out of the Elmore Events Centre during the five-day event, including booze and drugs buses from Melbourne and local highway patrol units.

Senior Sergeant Ian Brooks said police performed 430 drugs tests and 1420 preliminary breath tests.

“We prosecuted 38 people for returning a positive drug test and two for drink-driving,” he said.”

“There were in excess of 100 different traffic offences, ranging from speeding to not displaying P- or L-plates correctly.”

He said the results were disappointing, not only that people chose to do drugs, but then continued to drive afterwards, some planning to travel for long distances.

Drug issues were prevalent during the event, with medical staff on-site telling police of numerous occasions of people seeking assistance after falling ill.

GHB and LSD were reported to be the illicit substances causing the most issues.

Roadside drug tests performed by police during the blitz checked for methamphetamines and cannabis.

A dog operation during the first two days of the festival also found several people with drugs, including one who was subsequently charged with trafficking.
