Conditional Release

The state allows conditional release or alternative or diversion sentencing for people facing their first prosecutions. Usually, conditional release lets a person opt for probation rather than trial. After successfully completing probation, the individual's criminal record does not reflect the charge.

Local Decriminalization

This state has local jurisdictions that have enacted municipal laws or resolutions either fully or partially decriminalizing minor cannabis possession offenses.

Drugged Driving

Every state criminalizes driving under the influence of a controlled substance. Some jurisdictions also impose additional per se laws. In their strictest form, these laws forbid drivers from operating a motor vehicle if they have a detectable level of an illicit drug or drug metabolite (i.e., compounds produced from chemical changes of a drug in the body, but not necessarily psychoactive themselves) present in their bodily fluids above a specific, state-imposed threshold. Read further information about cannabinoids and their impact on psychomotor performance. Additional information regarding cannabinoids and proposed per se limits is available online.


This state has an active hemp industry or has authorized research. Hemp is a distinct variety of the plant species cannabis sativa L. that contains minimal (less than 1%) amounts of tetrahydrocannabinol (THC), the primary psychoactive ingredient in marijuana. Various parts of the plant can be utilized in the making of textiles, paper, paints, clothing, plastics, cosmetics, foodstuffs, insulation, animal feed, and other products. .


This state has legalized marijuana for recreational use.

Medical Marijuana

This state has medical marijuana laws enacted. Modern research suggests that cannabis is a valuable aid in the treatment of a wide range of clinical applications. These include pain relief, nausea, spasticity, glaucoma, and movement disorders. Marijuana is also a powerful appetite stimulant and emerging research suggests that marijuana's medicinal properties may protect the body against some types of malignant tumors, and are neuroprotective.
