The video, which has been seen by foxsports.com.au after being circulated on social media, shows Smith wearing sunglasses near what appears to be a white substance on the table of an apartment.
Smith is seen rolling up a banknote and picking up a credit card next to the white substance in the footage, while Munster is standing in the background among at least six people in the hotel room.
Now a second video has emerged of Munster dancing on a table and clutching what appears to be a small package containing white powder in his left hand.
