Read this too...
The contraceptive patch contains hormones similar to those in
birth control pills. Hormonal contraceptives are not for everybody.
Most side effects of the contraceptive patch are not serious and
those that are, occur infrequently. Serious risks, which can be
life threatening, include blood clots, stroke or heart attacks and
are increased if you smoke cigarettes. Cigarette smoking increases
the risk of serious cardiovascular side effects, especially if you
are over 35. Women who use hormonal contraceptives are strongly
advised not to smoke. Some women should not use the contraceptive
patch, including women who have blood clots, certain cancers, a
history of heart attack or stroke, as well as those who are or may
be pregnant. The contraceptive patch does not protect against HIV
or other sexually transmitted diseases.
Seems like it is not recommended for smoking women to use
it....hmmm.
