Busted Smuggling 8-Ball
... In Board Shorts
NHL star Jarret Stoll tried to smuggle cocaine and molly into a Vegas pool party ... by hiding them in his board shorts ... this according to the police report obtained by TMZ Sports.
Stoll was busted around 4:30 PM on Friday while going through the security area -- that EVERYONE goes through -- on the way in to the Wet Republic pool party at the MGM Grand.
Despite the sign CLEARLY warning people that they will be patted down on the way inside, Stoll took his chances ... and a security guard found a pink baggie with white powder and numerous "gel-caps" with an off-white powder inside consistent with the drug "molly."
According to the police report ... when asked if the powder inside the baggie was coke, Stoll said, "Yes."
Cops say Stoll had 3.3 grams of coke ... and 8.1 grams of molly.
He was transported to a nearby jail ... where he was booked for drug possession.
