The effects of Methamphetamine on foetus though have not yet been characterized and are even less understood on the development of childhood, they are known to have toxic effects on the nervous system of the foetus. Even its exposure is known to have adverse effects on growing infants. Indirect effects on foetus should be taken into consideration. The pregnant women who are consuming Methamphetamine are having increased anxiety, they go for less prenatal care, remain malnourished, go in to preterm labour and the intrauterine foetal growth is also retarded. At many places, theses effects are observed rather enhanced due to less spousal support. Moreover, if you are smoking it, nicotine along with has adverse effect on the growth of the foetus.
