I also assume you are blissfully ignorant of what drug use can do to a fetus. BTW my grand daughter had no vaccinations before we knew she was autistic. Getting babies to the pediatrician are a low priority to drug abusers.
Drug use is horrible and certainly could be a factor in autism However ignoring a whole body of evidence is also horrible
Looking at the thousands of zombies walking all around you on our streets shows what drug use does to teens and adults. They euphemistically call it “mental illness,” but it is basically drug-induced permanent brain damage.
