OH BABY –
August 6, 2025 – Women who strongly wanted to avoid pregnancy were significantly more likely to become pregnant if they engaged in heavy drinking. Their risk was 50% higher compared to women who drank moderately or did not drink at all.
On the other hand, cannabis use showed no connection to increased chances of undesired pregnancy. Women who used cannabis were just as likely to avoid pregnancy as those who didn’t use it.
The study began with a larger group of over 2,000 non-pregnant women between the ages of 15 and 34. From that group, researchers focused on 936 participants who expressed a clear desire not to get pregnant. Among them, 429 reported heavy alcohol use (based on a standard alcohol screening questionnaire), and 362 reported using cannabis. Of those cannabis users, 157 said they used it daily or almost daily.
