Normal spirometry at screening as demonstrated by FEVI +/- 80% of predicted and FVC +/- 80% of predicted.
Adequate veins, as assessed by the Investigator or Investigator's designee, that are suitable for the required number and frequency of PK blood draws in this study.
In otherwise good general health as determined by a complete medical history, physical examination, 12-lead electrocardiogram (ECG), blood chemistry profile, hematology, serology (HIV-l/2Ab, HBsAg, HCV Ab), and urinalysis at screening.
Female participants (if of child-bearing potential and sexually active) and male participants (if sexually active with a partner of child-bearing potential) who agree to use a medically acceptable and effective birth control method throughout the study and for one week following the end of the study.

Smokers must meet the following inclusion criteria (items 9-10):

A history of smoking> 15 cigarettes/day currently and for at least the last 2 years.
Serum cotinine +/-500 ng/mL at Screening Visit I.

Nonsmokers must meet the following inclusion criteria (items 11-12):

A history of never smoking> 5 cigarettes/day and not smoking at all for at least the last 2 years prior to Visit I.
Serum cotinine :o 40 ng/mL at Screening Visit I and a negative urine cotinine test at Visit 2 Day-I.

Exclusion criteria

Treatment with an investigational drug within 30 days ( or within 5 half-lives of the investigational drug, if>30 days) prior to Visit I.
Significant hepatic, renal, gastroenterologic, cardiovascular endocrine, neurologic (including history of seizures or stroke), or hematologic disease.
Any acute illness in the 5 days prior to Visit 2.
Upper respiratory tract infection within 6 weeks of Visit 2 or bronchitis or pneumonia within 6 months of Visit 2.

Hypotension or hypertension, at screening or baseline.
Poor veins in the opinion of the Investigator or the Investigator's designee such that the participant is judged to likely have difficult venipuncture during the study.
Any other disease or condition, by history, physical examination, or laboratory abnormalities that in the investigator's opinion, would present undue risk to the subject, or may confound the interpretation of study results.
Participation in another clinical trial within 2 months of the beginning of the present study, or blood donation or comparable blood loss (>350mL) within 2 months before the present study.
