Nevada's clean air laws apply to all indoor workplaces.
Smoking is prohibited in all indoor workplaces, except for certain bars, brothels, strip clubs, areas in casinos that minors may not enter, and enclosed areas within bars that minors may not enter.
Nevada does not require employers to create designated smoking areas or provide other accommodations for smokers in the workplace.
Nevada doesn’t specifically require employers to provide workplace accommodations for nonsmoker employees.
Nevada laws don’t address employer policies on smoking in the workplace. Local laws regulating smoking -- at the city, county, or town level -- may require employers to have a policy on smoking in some areas. And even though it’s not required by law in Nevada, employers are generally free to adopt policies on smoking in the workplace if they choose to.
An employer may not fail or refuse to hire, discharge, or discriminate in terms of compensation, benefits, or conditions of employment because of an employee's lawful use of any product offsite during nonwork hours, unless use adversely affects job performance or the safety of other employees. Employers are also prohibited from retaliating against employees or applicants who exercise their rights under the state's smoking laws.
If you want to go right to the source and look up Nevada law on workplace smoking laws -- or if you're writing a letter to your employer or employee and want to cite the applicable law -- the relevant statute(s) can be found at Nev. Rev. Stat. Ann. Sections 613.333 and 202.2483. Workplace smoking information is also available in Nolo's books Your Rights in the Workplace, by Barbara Repa (Nolo) and The Employer's Legal Handbook, by Fred Steingold (Nolo).
