O'Connor appeared in
public service announcements for Partnership for a Drug Free America and spent the rest of his life working to raise awareness about drug addiction. O'Connor also successfully lobbied to get the State of California to pass legislation allowing family members of an addicted person or anyone injured by a drug dealer's actions, including employers, to sue for reimbursement for medical treatment and rehabilitation costs and other economic and non-economic damages. The law, known as the Drug Dealer Civil Liability Act in California, went into effect in 1997. It is also referred to as The Hugh O'Connor Memorial Law. The act is based on the Model Drug Dealer Liability Act authored in 1992 by then Hawaii U.S. Attorney Daniel Bent. The Model Drug Dealer Liability Act has been passed in 17 states and the Virgin Islands. A website devoted to the Act can be found at:
www.ModelDDLA.com. Cases have been brought under the Act in California, Illinois, Utah and other states. His son's suicide inspired O'Connor to start a crusade against the man who sold the drugs to Hugh. He called Harry Perzigian "a partner in murder" and a "sleazeball". Perzigian filed a defamation lawsuit against the actor. In 1997, a California jury threw out the case. In an interview on CNN's Larry King Live soon after the verdict, O'Connor said he would never be able to put his son's death behind him. "I can't forget it. There isn't a day that I don't think of him and want him back and miss him, and I'll feel that way until I'm not here anymore," he said.
