None of the competitors at last night’s Strikeforce: Houston were tested for drugs due to the policy of the local commission, the Texas Department of Licensing and Regulation. Despite regulating one of the biggest MMA hotbeds in the country, the TDLR does not require that participants in combat sports be drugs tested unless there is “good cause” to do so. When the UFC last held an event in Texas (UFC 103), they formally requested that the TDLR test all fighters, a request that the commission complied with. This is in line with UFC policy that there will be drug testing at all its events, with the organisation even going as far as conducting its own drug testing when running shows outside of North Amerfica. For whatever reason Strikeforce did not request that the TDLR test its fighters for illegal and banned substances.
