David O´Reilly, BAT • Thanks to mass manufacturing, globalization, two world wars and population growth, the 20th century was the CIGARETTE CENTURY • Thanks to technology, the 21st century could be the e-CIGARETTE CENTURY • Nicotine is an important, useful, cultural drug. It gets mothers, fathers, professionals stimulations and relax through their stresses in their daily lives. • The world would be a poorer place without it. The possitive roles that nicotine plays in our society has been lost in the smoke of the TOBACCO WARS. • The past is past, this is a new era!
