Pot and pregnancy

A study published in the May issue of the journal Pediatrics analyzed the cognitive performance of 354 babies between 6 and 13 months, born to mothers who had used different drugs during pregnancy.
Alcohol use during pregnancy was associated with poorer cognitive performance. Cocaine and tobacco use was associated with smaller birth size. Cannabis use produced no detectable effects compared to mothers who abstained entirely.
