Short answer - of course not (no more than is alcohol).
‘Dr. Dana Gossett, a research obstetrician and gynecologist at the University of California, San Francisco who also treats patients, says studies show marijuana increases the risk of stillbirth and adversely affects how a baby’s brain develops.
‘Gossett cites some research that suggests children exposed to marijuana while growing in the womb can have poorer performance on visual-motor coordination — tasks like catching a ball or solving visual problems like puzzles.
‘And studies also show, she says, these kids may have behavioral problems at higher rates than other children by the age of 14, and are at greater risk for initiating marijuana use.’
Having raised one adopted child born withdrawing from drugs and currently raising the second I can’t begin to tell you the harm caused these little ones. Anyone who does drugs during pregnancy should lose the child and be sterilized before they can harm another innocent life
