Cannabis (marijuana) during pregnancy is dangerous for the fetus
During pregnancy, the active component of cannabis, which is THC (tetrahydrocannabinol), can go into the placenta and affect the fetus, including its birth weight (like the case in the question here) and brain function, reducing the baby's IQ and attention capacity.
Depending on the type of drug and the quantity consumed, it is also possible that the baby suffers from weaning at birth, that is to say from deprivation (inconsolable crying, irritability, tremors, feeding difficulties, etc.). .
Cannabis may also have longer-term effects in children (learning disabilities, behavioral problems, hyperactivity, etc.).
