Every day, about 5.4% of pregnant women in the United States used illicit drugs in 2018 to 2019, and the effects can reach far beyond the prenatal period. This post pulls together findings on screening, treatment choices, and policy changes, showing which approaches reduce relapse, improve birth outcomes, and lower risks like NAS. It also tracks how substances like alcohol, tobacco, opioids, and cannabis influence pregnancy and child health across the globe.
Key Takeaways

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
