In brief: No single answer
Exposure of the developing brain to different types of drug certainly is one source of mr. There is no single mechanism. Broadly, incredibly complex neuron development and migration patterns result in normal brain function.
Even slight disturbances in those delicate processes can lead to "bad brain." the amazing thing is how well protected the fetus is under most circumstances.

In brief: Depends on drug
Alcohol is a teratogen, meaning it causes actual changes in structure as well as function of the fetal brain.
It also impacts fetal body and brain growth, as can tobacco, cocaine, methamphetamine, heroin, mj, pcp's, etc. Some can cause lack of oxygen and nutrients, strokes and bleeding in the fetal brain. An active user parents differently when " high" or " stoned, " negatively impacting development.
