Fetal tobacco smoke exposure causes permanent physiological harm
Is it true that fetal tobacco smoke exposure causes permanent physiological harm?
Yes. Fetal tobacco smoke exposure causes permanent physiological harm, as supported by substantial clinical and epidemiological evidence linking it to long-lasting neurodevelopmental, structural, and metabolic deficits in offspring.
Verdict: SUPPORTED · 6 sources for, 0 against · Last checked
The retrieved literature strongly supports the claim that fetal exposure to tobacco smoke leads to lasting physiological and cognitive impairments. Multiple papers confirm associations with altered birth size, disrupted white matter and brain development, learning disabilities, and long-term health consequences lasting into adulthood. There are no papers refuting the claim.
