Tobacco smoking during pregnancy causes many detrimental effects on health and reproduction, in addition to the general health effects of tobacco.A number of studies have shown that tobacco use is a significant factor in miscarriages among pregnant smokers, and that it contributes to a number of other threats to the health of the foetus.
Smoking during pregnancy is dangerous to the unborn baby and may cause pre-term birth, birth defects such as cleft lip or cleft palate, or miscarriage. [93] [80] Tobacco is the most commonly used substance among pregnant women, at 25%. [87] [94] Nicotine crosses the placenta and accumulates within
Nicotine itself could be at least partly responsible for many of the adverse after birth health results related to cigarette use while the mother was pregnant. [40] There is evidence that nicotine negatively affects fetal brain development and pregnancy outcomes. [42] There is also risk of stillbirth and pre-term birth. [43]
[90] A 2014 US Surgeon General report found "that nicotine adversely affects maternal and fetal health during pregnancy, and that exposure to nicotine during fetal development has lasting adverse consequences for brain development." [14] Nicotine prenatal exposure is associated with behavioral abnormalities in adults and children. [107]
Substance examples of long term effects as follows: Alcohol exposure has shown it could lead to poor growth. Tobacco exposure can make it more likely to get obese. Alcohol, nicotine, and opiate exposure have shown to lead to attention deficits. Nicotine and alcohol exposure affect learning and memory.
While acute/initial nicotine intake causes activation of neuronal nicotine receptors, chronic low doses of nicotine use leads to desensitization of those receptors (due to the development of tolerance) and results in an antidepressant effect, with early research showing low dose nicotine patches could be an effective treatment of major ...
Smoking during pregnancy can cause adverse health effects in both the woman and the fetus. The 2008 US Guideline determined that "person-to-person psychosocial interventions" (typically including "intensive counseling") increased abstinence rates in pregnant women who smoke to 13.3%, compared with 7.6% in usual care.
Nicotine has been demonstrated to alter the amounts of brain-derived neurotrophic factor in humans. [266] Nicotine could make cancer therapies less effective. [267] Based on in vitro and in vivo effects of nicotine, patients should be advised not to use nicotine products during cancer treatment unless it is temporarily needed to stop tobacco ...
