and the tour was cancelled, as audience members were smoking pot during performances. Such exposure would cause Chong to violate the terms of his parole. In 2006, Chong published a memoir about his experiences in jail and his exploration of meditation, called The I Chong: Meditations from the Joint. In 2010, Chong and Cyril Wecht appeared at a Democratic Party fundraiser in Pittsburgh, Pennsylvania, to aid the campaign against Mary Beth Buchanan, the United States Attorney who prosecuted him. She was running as a Republican candidate for the United States House of Representatives. She was defeated in the Republican primary. Seizure of a/k/a Tommy Chong DVDs On May 7, 2008, federal agents raided Spectrum Labs in an investigation related to its "detoxification" products. The search was one of nine conducted for Operation True Test, an investigation being led by Buchanan, still the U.S. Attorney for the Western District of Pennsylvania. It targeted companies that sold so-called "masking products," intended to help drug users pass employer drug tests. No federal law bans such products; they are regulated on a state-by-state basis. Of the nine search warrants issued, none was for businesses within Buchanan's district. Chong claimed that federal agents had seized 8,000–10,000 copies of the yet-to-be released documentary, a/k/a Tommy Chong, from Spectrum Labs, but their attorney said no DVDs were taken. In a press release, Chong said, "[The seizure of the DVDs is] a way to punish the distributor financially. There's no way to get the DVDs back until the investigation is over." Chong said he did not have any ownership of the film. The Pittsburgh Post-Gazette later amended its story, saying that an "undisclosed number of DVDs was taken". It noted the government is not required to disclose a reason for the seizure as the raid was part of "an ongoing investigation".
