I guess it's cultural. Human consumption of alcoholic beverages goes back to thousands of years while tobacco has been used in Europe since the 15th century when it was brought back from America.

Wine is present in the Bible and used in Christian churches during mass. It is also used in Jewish celebrations and holidays.

Tobacco doesn't have the same history and cultural impact. From what I understand it is/was mainly "spiritually" used by American Natives for shamanic celebrations. (I can clearly be wrong on that)
