Yet known the full extent of the effects of prenatal exposure to cocaine, but scientific studies indicate that these babies are born prematurely and underdeveloped: less weight, lower skull diameter and shorter length.

The precise determination of the consequences for the newborn is complex and varies according to the drug that was consumed by the mother.

Added to that, we know statistically that mothers addicted to cocaine abuse in one or more other substances. The picture is complicated when considering the amount and variety of drugs of abuse, lack of prenatal care, socioeconomic status, exposure to infectious diseases, other health problems, poor nutrition, and many other factors involved directly on the health of the fetus and newborn.

It has been found that exposure to cocaine during fetal development can cause delays and other mental deficiencies, as well as inability to sustain attention and concentration for minimum periods to enable learning. Despite the severity of injuries and disorders suffered by these children, modern processing techniques allow for a meaningful recovery. Either way, the fact that these data and advances are only palliatives, and not be taken as 100% effective.

Cocaine stimulates the central nervous system. The immediate effects include:

*dilated
*increased blood pressure,
*heart rate and respiratory
*increase in body temperature
*Occasional use can cause …
*congestion or drainage from the nose
*ulceration of the mucous membrane of nose

These symptoms can cause death from cardiac or respiratory failure. Also present irritation and ulcers in the nasal mucosa.

Commonly causes nasal congestion that can occur with or without liquid secretion. The use by injection exposes the addict to HIV infections, hepatitis B and C and other infectious diseases. Infection with HIV can occur through the direct transmission of virus by sharing needles and other devices contaminated.
