A committee of Minnesota lawmakers will hold a hearing Tuesday to address the rise in synthetic drug use in the state.
Last month, the Duluth City Council passed two ordinances designed to clamp down on the sale and use of synthetic drugs.
One would require retailers to obtain a license to sell synthetic drugs, and the other would make it illegal to smoke, ingest, inject or snort any product with a label that says it is not for human consumption.
Council member Sharla Gardner, a co-sponsor of the ordinances, said authorities have had a hard time regulating the synthetic drug industry because chemists create new compounds as quickly as others are outlawed.
