Survey results indicate that smoking
and alcohol and marijuana use increased among residents of Manhattan during the
5~8 weeks after the terrorist attacks on the World Trade Center winch took place
on September 11, 2001. Almost one-third of the nearly 1,000 persons interviewed
reported an increased use of alcohol, marijuana, or cigarettes following the
September 11th attacks. The largest increase was in alcohol use. About
one-fourth of the respondents said they were drinking more alcohol in the weeks
after September 11; about 10% reported an increase in smoking, and 3.2% said
they had increased their use of marijuana. The investigators found survey participants by randomly dialing New York City phone numbers and screened potential respondents for Manhattan residents living in areas close to the World Trade Center.
