The drug bupropion (Zyban) is an option for people who
have been unsuccessful using nicotine replacement. The
drug was originally prescribed as an antidepressant, and its
use in smoking cessation was discovered by accident.
Researchers knew that smokers trying to quit were often
depressed, so they began experimenting with bupropion as
a means to fight depression, not addiction. It reduces the
withdrawal symptoms associated with smoking cessation
and can be used in conjunction with nicotine replacement
therapy. Researchers suspect that bupropion works directly
in the brain to disrupt the addictive power of nicotine by
affecting the same chemical neurotransmitters or messengers
(such as dopamine) that nicotine does.
The pleasurable aspect of addictive drugs like nicotine
and cocaine is triggered by the release of dopamine. Smok-
ing f loods the brain with dopamine. The New England Journal
of Medicine published the results of a study of more than
600 smokers taking bupropion. At the end of treatment, 44
percent of those who took the highest dose of the drug (300
mg) were not smoking, compared to 19 percent of the group
who took a placebo. By the end of one year, 23 percent of
the 300 mg group and 12 percent of the placebo group were
still smoke-free. Using Zyban with nicotine replacement
therapy seems to improve the quit rate a bit further. Fourweek
quit rates from the study were 23 percent for placebo,
36 percent for the patch, 49 percent for Zyban, and 58 percent
for the combination of Zyban and the patch.
Avoiding Environmental Tobacco Smoke
You don’t have to smoke to suffer from the effects of nicotine.
Environmental tobacco smoke (ETS) causes health
problems in nonsmokers. You can reduce the impact of this
stress on yourself and others by taking some of these actions
to avoid or help ban ETS:
• Stop patronizing restaurants, bars, cafes, or similar
businesses that allow smoking. Write to them to say
they are losing your business for that reason. (If you
really love the food, suggest smoking sections in a
separately ventilated enclosure.)
• Write letters to the editor, naming names and
identifying a particular smoke-filled restaurant
or other business. State your reasons for not
patronizing the business. Negative press works
wonders!
• Make a point of congratulating restaurants, bars,
cafes, or smaller businesses on creating smoke-free
environments. Write letters, naming names to create
positive press for their efforts.
If you live with a smoker or are smoking in your home,
here are some ways to avoid ETS:
• Stop smoking inside the home. If you must smoke,
go outdoors.
• Create a separate smoking room with its own
ventilation system and air seals to keep the smoke
out of the rest of the house.
• Install a more effective ventilation system with a
supply of outside air and a special filter called a
particulate filter.
