In a handful of tweets, Wise said he smelled a "strong reefer aroma" June 4.
Wise said he did not see anyone smoking marijuana nor did he smell marijuana on anyone specifically.
The Cavaliers organization had no comment about the assertion.
Twitter users responded by saying Wise is a "snitch" and made fun of his choice to use the word "reefer."
The Cavs are down 0-2 in the 2017 NBA Finals as of June 5. The Cavs take on the Warriors Wednesday in Game 3 in Cleveland at Quicken Loans Arena.
