The Mitchell Report also stated that interviews were requested of five MLB players who had spoken out publicly on the steroid issue. Of these players, only one, Frank Thomas , was willing to be interviewed. The Mitchell Report stated that there was no evidence that any of these five had used performance-enhancing drugs. Curt Schilling , one of the four players who declined to interview with Mitchell, explained that he denied Mitchell's request because he "would have nothing to offer" Mitchell's investigation "other than personal opinion and hypotheticals." 
Most drugs of abuse are addictive. Addiction is a chronic, relapsing disease characterized by compulsive drug seeking and use despite negative consequences and by long-lasting changes in the brain. People who are addicted have strong cravings for the drug, making it difficult to stop using. Most drugs alter a person’s thinking and judgment, which can increase the risk of injury or death from drugged driving or infectious diseases (., HIV/AIDS, hepatitis) from unsafe sexual practices or needle sharing.
