What should pregnant individuals generally be cautious about using?

Pregnant individuals should exercise caution, especially regarding the use of illicit drugs. This is because illicit drugs can pose significant risks to both the mother and the developing fetus. The use of such substances can lead to adverse outcomes such as preterm labor, low birth weight, developmental issues, and other health complications. Additionally, these drugs may affect the body's natural physiological processes during pregnancy, potentially leading to long-term health issues for the child.

While it is essential for pregnant individuals to be careful with any substances—including natural supplements and homeopathic remedies as they may also carry risks or lack sufficient safety data—it is the illicit drugs that are most clearly associated with serious negative effects on both maternal health and fetal development. Therefore, being cautious about the use of illicit drugs is paramount during pregnancy to ensure the health and safety of both the mother and her child.
