Perhaps you should be more careful with reading ;)

Sure it aids in the absorption... well metabolisation of Clopidrel which is in anticoagulant.

Cigarette smoking is a known inducer of CYP1A2 and its activity increases relative to the number of cigarettes smoked per day. Importantly, CYP1A2 is the predominant isoenzyme responsible for the first of the two oxidative steps required for clopidogrel to be metabolized into its active metabolite.

I think the risk of clot formation from smoking though (especially in those on medications such as oral contraceptives or HRT) far outweighs any benefit of Clopidrel synergy. Seems contradictory but w/e. Just my 2c.

Anyway, back to the topic at hand.

As another BENEFIT of smoking I would say it helps stop hiccups! If you ever have the hiccups - one drag of a cigarette is usually enough to stop them! xD

Smoking also tends to be somewhat of a social lubricant especially in many european countries.
