Should filler weight be included in Ohio drug cases? Many drug offenses are based on the weight of the controlled substance found in the suspect’s possession. However, the tests performed by the Bureau of Criminal Investigation (BCI) do not test for the purity of the substance. When cocaine is cut with sugar or some other filler material, should the level of offense be based on the actual weight of the cocaine or the total weight of the cocaine and filler? Most appellate districts in Ohio have ruled that the total weight of the controlled substance and filler can be used.
