A responsible press would encourage Obama to smoke more and drink less.
Obama comes from two long lines of alcoholics: His father died driving drunk. His half-brother David died driving drunk. His half-brother Roy was an alcoholic before discovering teetotaling Islam and changing his name to Abongo. His maternal grandfather Stan was a barfly.
Back during the Pennsylvania primary, Hillary was always gulping down boilermakers, hoping (I imagine) to provoke Barack Jr. into responding in kind to demonstrate his regular guyness and then going off on a Barack Sr.-style bender. (Barack Sr.'s standing order at his favorite Nairobi bar was two double shots of Jack Daniels as soon as he walked in the door.)
With that kind of genetic background combined with his stressful job, the President should avoid drinking.
On the other hand, the President does need to self-medicate his fragile emotional state right now, so let him do it with cigarettes. So what if he dies of lung cancer at 75 rather than of something else at 85? We're paying him to be President in his 40s.
