Does smoking prevent pregnancy?

No: No, smoking doesn't prevent pregnancy. News reports have China with >300 million and India with >200 million smokers, yet they still have problems with population growth. Smoking is bad news for an individual's health and bad for the community (smoking-related diseases costs our society a huge amount of money to treat).

Nope: Smoking harms all tissues, but isn't known as a contraceptive. In fact, medical experts recommend that women in child bearing years who smoke use contraception to avoid getting pregnant and harming the fetus.

NO: while smoking may have adverse effects of women's fertility, that effect is highly variable and generally quite modest. What prevents pregnancy is adequate contraception - ideally long-term like provera (medroxyprogesterone) injections or other reliable hormonal contraception, barrier protections like condoms and spermicide or diaphragms and spermicide (not as good) and IUDs (almost as good or equal). Don't gamble!!!
