This is not your old man’s marijuana.

Authorities say a burgeoning domestic pot industry has transformed the potency of the weed now hitting the streets.

In the past, law enforcement says they mostly seized compressed marijuana bricks. Now they are mostly intercepting medical-grade, domestic marijuana.

A Rocky Mountain High Intensity Drug Trafficking Area study found busts involving Colorado weed were made last year in 23 states.

Information obtained by The Associated Press through an open records request shows the Kansas Highway Patrol made 468 felony drug trafficking arrests last year. The agency arrested 187 people during the first five months this year. Most of the pot seized came from Colorado.

Troopers also seized $4 million in cash last year, and $1.3 million during the first five months of this year.
