If the police believe you are under the influence, and if you refuse a breathalyzer, in Nevada you will be arrested, taken to jail, and your blood will be drawn via warrant. Therefore, it's just not worth it to refuse. Your blood will be taken regardless, which could then show drugs in your system, whereas a breathalyzer only shows alcohol content. In other states, you may receive an automatic 6 month or 1 year license suspension for refusing.
