Marijuana testing is coming to the NBA, and the players' union wants its rank and file to know the time to stop partying is now. Player representatives for the 29 teams were told at the union's annual meeting in the Bahamas to spread the word to their teammates about the league's new drug policy. Since marijuana can stay in a person's system for two to three months, players who use it in July run a risk of getting caught in October. "I would think that if guys are using, they got the message last year that they'll be tested," Tyrone Corbin of the Hawks said.

Steroids also were added to the league's banned substances list during the last collective bargaining negotiations. All players will be tested when training camps open in October.
