Voluntary intoxication is a defense to specific intent crimes in Nevada, but not one that is easily put forth. The general feeling of everybody, judges included, is that if you choose to get that wasted you are responsible for whatever you do.
You may want to consult with a local attorney about whether your case meets the narrow standard of successful defenses in NV.
Intoxication is not a defense nor is it a good defense theory because then you cannot effectively rebut the police officer's testimony if you were impaired.
