The prison guard who was convicted of dealing drugs at his Port Coquitlam pretrial centre will be spending time behind bars himself, following his sentencing Friday.

North Fraser Pretrial Centre guard Roger Moore was convicted on four counts of drug trafficking, and on Friday was sentenced to four years in prison.

The court heard Moore had smuggled in pot, ecstasy and anabolic steroids. The value in prison: more than $20,000.

"Certainly it's unusual to be involved in the investigation when it involves one of the corrections officers in the trafficking of illegal drugs," RCMP Sgt. Peter Thiessen said Friday.

"One incident like this is one too many."

But it's not the first time a North Fraser guard has found himself in trouble. Last October, a guard pleaded guilty to helping an inmate escape.

Former inmate Glen Flett says that drugs are readily available in prison.

"You can probably on any given day get high in prison," he said.

And Flett says it's not uncommon to get the help of staff members to smuggle in drugs.

Last summer, the federal government announced it was spending $120 million to help eliminate drugs in federal prisons. It has added more drug dogs and stepped-up searches, but Flett says it won't be enough.

"About as realistic to get rid of them on the east side of Vancouver," he said.
