Though some say smoking is a sin, the bible does not refer to smoking whatsoever. As for alcohol, the bible does say "The blood of Christ". In communion, the blood of Christ is the wine. Either way, neither is a true sin in religion.
The only Church I can think that thinks smoking and drinking are a sin is the Jesus Christ of Latter Day Saints. They do not even believe in coffee, tea or chocolate. Otherwise, other religions don't seem to be bothered by it.
