PONTIAC, Mich. -

A jury has ruled in favor of a Detroit-area gas station and a product distributor sued by the family of a 20-year-old man who committed suicide after using so-called synthetic marijuana.

Records show a "no cause" verdict was issued Thursday following the civil trial in Oakland County Circuit Court in Pontiac.

John Sdao died in 2012 after using Spice that was sold by the Royal Oak gas station. Spice is a mix of dried herbs and spices sprayed with chemicals. Michigan banned synthetic marijuana in 2012.

Defense attorney Dean Kallas said Tuesday that the jury ruled "the suicide was unrelated to the product."

Sdao's family was seeking $10 million. Their attorney James Rasor says he wants the state Appeals Court to "clarify the law" on the ruling.
