Smith testified in the Pittsburgh drug trials of September 1985. As with other major league players, he was granted immunity from prosecution in exchange for his testimony. In February 1986, Smith, along with six other players, was determined to have been a prolonged drug user who had also facilitated distribution to other players, and was suspended for a full season. All the suspended players were allowed to continue playing under the condition that they donated ten percent of their base salaries to drug-related community service, submitted to random drug testing, and contributed 100 hours of drug-related community service.
