what is 'Teetotalism'???

Teetotalism is the practice and promotion of complete (or T-total) abstinence from alcoholic beverages. A person who practices (and possibly advocates) teetotalism is a called a teetotaler or teetotaller (plural teetotalers or teetotallers.)

People generally choose teetotalism for religious, health, family, or societal reasons, or from a combination thereof. This does not necessarily mean that they cannot participate in social drinking; for instance, for the typical teetotaller, soft drinks are an easily obtainable substitute at most drinking establishments.

Contemporary and colloquial usage has somewhat expanded teetotalism to include strict abstinence from most recreational intoxicants (legal and illegal, see controlled substances). Most teetotaller organizations also demand from their members that they do not promote or produce intoxicants.
