It happened Friday night at the Mardi Gras Casino.
A trooper was watching surveillance video when he saw Joshua T. Wilkerson, 28, and Selwyn G. Brewer, 45, get into a car illegally parked in a handicapped spot.
The trooper says he saw Wilkerson give Brewer pills, then watched Brewer crush and snort the pills. The dome light of the vehicle was on during the event.
Officers approached the vehicle and informed them of what they saw, then arrested Wilkerson and Brewer.
Wilkerson is facing charges of possession with intent to deliver, public intoxication, conspiracy to commit a felony and illegally parking in a handicap parking spot. He is also facing a charge of littering, after the trooper witnessed him dispose of a hamburger wrapper in the parking lot.
There is no word yet on what charges Brewer faces.
