Feds Target Synthetic Marijuana Ring

An effort by state and federal lawmakers to combat the manufacture and distribution of synthetic marijuana has had only limited success. Known as K2, Kush, Klimax and a variety of other names, the drugs are still finding their way onto American streets – with deadly results.

Federal prosecutors have announced a 13-count indictment naming 16 people accused of making or selling synthetic marijuana, including a college professor. ABC’s Jim Ryan has updates from Dallas, Texas.
