  • Given nicotine's relatively short biological half life, it's going to depend a lot on how long before the workout, so you may want to specify. – Tyler Dec 26 '14 at 6:04
  • Along with the above i would also specify that it would also depend in the fitness regime you are following. – user285oo6 Dec 26 '14 at 16:33
  • What are you doing "in the gym" ? – Eric Dec 27 '14 at 4:19
  • Provide more details: cardio? Weightlifting? Effects of smoking on general performance? – Kneel-Before-ZOD Jan 11 '15 at 22:43
