Changes in the use of intoxicants after onset of pregnancy

A sample of 416 pregnant women were interviewed with emphasis on their use of alcohol, tobacco, and legally prescribed and illegal drugs before and after onset of pregnancy. The results indicate a significant reduction in alcohol consumption, tobacco smoking and the use of legally prescribed and illegal drugs in connection with the pregnancy. There was no correlation between socio‐economic level and use of intoxicants. There was a correlation, however, between the use of intoxicants by the pregnant women and the use of such substances by other significant persons in their environment.
