A new development has been made regarding John Stamos' recent DUI arrest.
According to TMZ, law enforcement officials believe the 52-year-old actor was under the influence of GHB, an intoxicant commonly used as a date rape drug, when he was arrested in Beverly Hills in June.
John was allegedly using the drug as a fitness supplement to "lean out body mass" in preparation for his new TV shows, Grandfathered and Fuller House, a source told the entertainment news outlet.

Following his arrest, John was hospitalized to be treated for an unknown medical condition. He subsequently entered a rehab facility in July and checked out after a one-month stint.

That's the key," the star said of his recent rehab stint in an interview with Details.
