Study Groups

Smokers
All participants receive both Novolin R (experimental drug) and 14% NaCl (Sodium Chloride) solution (placebo), to be administered in randomly assigned order on two separate testing sessions. During administration of either Novolin R or 14% NaCl, participants will receive 1 spray in each nostril every 3 minutes for a total of 6 sprays. The nasal spray bottle delivers 0.1 ml of liquid per spray. Since the concentration of insulin in Novolin R is 100 IU/mL, six sprays will deliver a 60 IU dose.
Novolin R
Novolin R is a sterile, clear, aqueous, and colorless solution that contains human insulin (rDNA origin) 100 units/mL, glycerol 16 mg/mL, metacresol 3 mg/mL, zinc chloride approximately 7 mcg/mL and water for injection. The pH (potential Hydrogen) is adjusted to 7.4. Hydrochloric acid 2N (concentration) or sodium hydroxide 2N may be added to adjust pH. Novolin R vials are latex-free. The drug substance is being purchased from McKesson.
Non-Smokers
All participants receive both Novolin R (experimental drug) and 14% NaCl solution (placebo), to be administered in randomly assigned order on two separate testing sessions. During administration of either Novolin R or 14% NaCl, participants will receive 1 spray in each nostril every 3 minutes for a total of 6 sprays.
