Primary Outcome Measures :
  1. Area Under the Plasma Concentration Versus Time Curve From Time Zero to Time t [AUC(0-t)] [ Time Frame: Blood samples taken pre-dose and post-dose at 3, 5, 10, 15, 20, 30, 40, and 50 minutes, and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours ]
    AUC(0-t) was evaluated using the trapezoid rule.

  2. Maximum Observed Plasma Concentration [Cmaximum (Max)] [ Time Frame: Blood samples taken pre-dose and post-dose at 3, 5, 10, 15, 20, 30, 40, and 50 minutes, and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours ]
    Cmax was depicted from plasma concentration of nicotine.


Secondary Outcome Measures :
  1. AUC [0-infinity (Inf)] [ Time Frame: Blood samples taken pre-dose and post-dose at 3, 5, 10, 15, 20, 30, 40, and 50 minutes, and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours ]
    AUC (0-inf) was evaluated using the trapezoid rule.

  2. Time to Reach Maximum Plasma Nicotine Concentration (Tmax) [ Time Frame: Blood samples taken pre-dose and post-dose at 3, 5, 10, 15, 20, 30, 40, and 50 minutes, and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours ]
    Tmax was time at which Cmax of nicotine was reached.

  3. Apparent Elimination Half-life of Nicotine T(1/2) [ Time Frame: Blood samples taken pre-dose and post-dose at 3, 5, 10, 15, 20, 30, 40, and 50 minutes, and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours ]
    T(1/2) was calculated using plasma time-concentration values.

  4. Elimination Rate Constant for Plasma Nicotine: K (el) [ Time Frame: Blood samples taken pre-dose and post-dose at 3, 5, 10, 15, 20, 30, 40, and 50 minutes, and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours ]
    Kel was calculated with the help of plasma time concentration values.
