Marijuana, cocaine, and, in some communities, LSD, have been the drugs of choice in Nebraska over the past few years. Most marijuana in Nebraska grows wild, but the State also has some indoor operations that use modern technology. The Nebraska State Patrol operates a marijuana eradication program; the Nebraska Civil Air Patrol takes part. Illegal drug activities occur in all parts of the State, particularly in the more populous areas on major highway systems. The availability and demand for methamphetamine has increased rapidly in the last 2 years. Arrests for methamphetamine in the area have also increased significantly in the region.

Hospitals do not keep statistics on cases related to methamphetamine, but they have reported increasing numbers of such cases.
