AG Yost Announces Quantitative Analysis of Marijuana at BCI


(COLUMBUS, Ohio) — Ohio Attorney General Dave Yost today announced that the Bureau of Criminal Investigation (BCI) has implemented the quantitative analysis of marijuana in drug evidence seized by law enforcement.

“BCI’s new ability to differentiate between marijuana and hemp creates a valuable resource for officers who depend on our laboratory services, offered at no cost to them,” Yost said. “This major achievement bolsters our reputation as the leading crime lab in the state.”  

BCI has completed the validation of new instrumental methods for cannabis vegetation and oils, meeting new legal requirements recently established by Senate Bill 57. The quantitative analysis of a sample determines the tetrahydrocannabinol (THC) content.

Senate Bill 57 changed the Ohio Revised Code definition of marijuana to exclude hemp, defined as cannabis containing not more than 0.3% THC as calculated on the dried weight. With this definitional change, marijuana could no longer be identified conclusively with past techniques such as microscopic examination and chemical color testing.

“Ohio prosecutors are very appreciative of the hard work that Attorney General Yost and BCI have done to bring this critical testing capability to Ohio,” said Louis Tobin, executive director of the Ohio Prosecuting Attorneys Association. “Since the legalization of hemp last summer, law enforcement has struggled to enforce Ohio marijuana laws due to an inability to distinguish between marijuana and hemp. Expensive private testing was often the only solution. With the Attorney General’s announcement today, Ohio prosecutors will be better able to enforce our drug laws and protect Ohioans. We look forward to our continued partnership with the Attorney General and his staff as we work to keep Ohio safe.”
Soon after the bill became law, the Ohio Attorney General’s Office offered grant funding for law enforcement agencies to test suspected marijuana at other accredited laboratories until BCI could modify its testing techniques. Law enforcement agencies received $3,972 in grant funding to test samples in eight cases tied to over 20 felony charges.
BCI is currently pursuing additional validation studies for quantitative testing of other THC-infused food products.
