More Information

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.

EXPUNGEMENT

This state has enacted legislation explicitly providing the opportunity for those with marijuana convictions for activities that have since been decriminalized/legalized to have past marijuana convictions expunged, vacated, otherwise set aside, or sealed from public view.

Mandatory Minimum Sentence

When someone is convicted of an offense punishable by a mandatory minimum sentence, the judge must sentence the defendant to the mandatory minimum sentence or to a higher sentence. The judge has no power to sentence the defendant to less time than the mandatory minimum. A prisoner serving an MMS for a federal offense and for most state offenses will not be eligible for parole. Even peaceful marijuana smokers sentenced to “life MMS” must serve a life sentence with no chance of parole.

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.

Legalization

Generally, legalization means a policy that supports a legally controlled market for marijuana, where consumers can buy marijuana for personal use from a safe legal source.
