According to a longitudinal study published in 1991, and done in the 1980's in Jamaica by Melanie Dreher, RN, PhD, FAAN, and funded by the National Institute on Drug Abuse and the March of Dimes, at 3 days after birth, there was no difference in babies who were exposed to cannabis, and those who were not. After 30 days, the exposed babies did better on comprehensive evaluations than non-exposed babies. After 4 years, there was no significant difference between the two groups. At 5 years of age, after the children had started school, the McCarthy scale and something called "the home scale" again showed no difference between exposed children and non-exposed children. A video of a presentation of this study by Dr. Dreher at the Patients Out of Time Conference in Asilomar in July of 2008 is available <a href> http://vids.myspace.com/index.cfm?fuseaction=vids.individual&videoid=39313123&searchid=b4885688-abdb-4dac-b6b8-1ab5e62b525a

"here" </a>. NIDA did not continue funding the study at this point, because the study did not show the harm they expected to see.

Yes.

Smoking puts carbon monoxide the blood steam. Blood prefers to attach to carbon monoxide over oxygen, a fetus's blood more so. When there is too much carbon monoxide, it deprives the child of oxygen - which is needed for proper growth and development.

As well, the child is still subject to the rest of the chemicals in cigarets.

There is no safe level of exposure to secondhand smoke and that, on average, children are exposed to more secondhand smoke than adults. Children are significantly affected by secondhand smoke. Children's bodies are still developing, and exposure to the poisons in secondhand smoke puts them at risk of severe respiratory diseases and can hinder the growth of their lungs. Secondhand smoke is a known cause of low birth weight, Sudden Infant Death Syndrome (SIDS), Asthma, bronchitis, pneumonia, middle ear infection, and other diseases.

These are some of the effects of second hand smoke:

Low Birth Weight

  • Secondhand smoke is a known preventable cause of low birth weight, which contributes to infant mortality and health complications into adulthood. Secondhand smoke exposure reduces the birth weight of infants of nonsmoking mothers and contributes to additional reductions in birth weight among babies of smoking mothers.
  • Nonsmoking pregnant women who are exposed to secondhand smoke tend to give birth to infants who have a reduced mean birth weight of 33g or more. Secondhand smoke exposure also increases the risk of a birth weight below 2,500g by 22 percent.

Sudden Infant Death Syndrome (SIDS)

  • Maternal smoking is the strongest risk factor leading to SIDS.
  • Infants who die from SIDS tend to have higher concentrations of nicotine in their lungs than do control children, regardless of whether smoking is reported.

Cognitive Impairments

  • Secondhand smoke exposure impairs a child's ability to learn. It is neurotoxic even at extremely low levels. More than 21.9 million children are estimated to be at risk of reading deficits because of secondhand smoke. Higher levels of exposure to secondhand smoke are also associated with greater deficits in math and visuospatial reasoning.
  • The offspring of mothers who smoke one pack of cigarettes per day during pregnancy have an IQ score that is, on average, 2.87 points lower than children born to nonsmoking mothers.

Behavioral Problems

  • Children born to women nonsmokers who are exposed to secondhand smoke during pregnancy and to women who smoked during pregnancy are more likely to suffer from Attention Deficit Hyperactivity Disorder (ADHD) and conduct disorder.
  • Girls are exposed to higher rates of secondhand smoke than boys, but boys have greater problems with hyperactivity, aggression, depression, and other behavioral problems.

Respiratory Problems

  • The U.S. Environmental Protection Agency (EPA) has reported that secondhand smoke exposure increases the risk of lower respiratory tract infections such as bronchitis and pneumonia. The EPA estimates that between 150,000 and 300,000 annual cases of lower respiratory tract infections in infants and young children up to 18 months of age are attributable to secondhand smoke exposure. Of these cases, between 7,500 and 15,000 result in hospitalization.
  • Infants whose mothers smoke are 50 percent more likely to be hospitalized with a respiratory infection during their first year when compared to infants with nonsmoking mothers. Infants whose mothers smoke in the same room have a 56 percent higher risk of being hospitalized compared to infants whose mothers smoke in a separate room. There is a 73 percent higher risk if mothers smoke while holding their infants and a 95 percent higher risk if mothers smoke while feeding their infants.
  • Early exposure to cigarette smoke is a likely significant independent risk factor for subsequent respiratory disease. It is likely that in utero damage is compounded by increased susceptibility to the effects of continued postnatal secondhand smoke exposure.

Asthma

  • Asthma attacks are perhaps the most well-known health effect of secondhand smoke exposure among children. Secondhand smoke exposure increases the frequency of episodes and the severity of symptoms in asthmatic children. The EPA estimates that 200,000 to 1,000,000 asthmatic children have their condition worsened by exposure to secondhand smoke.
  • Secondhand smoke exposure is associated with increased respiratory-related school absenteeism among children, especially those with asthma.
  • Maternal and grand maternal smoking may increase the risk of childhood asthma. Relative to children of never-smokers, children whose mothers smoked throughout the pregnancy have an elevated risk of asthma in the first five years of life. Children whose mothers quit smoking prior to the pregnancy show no increased risk.
  • Secondhand smoke exposure causes children who already have asthma to experience more frequent and severe attacks.
  • Maternal smoking, in utero and later, is significantly related to lifetime wheezing in offspring.

Repercussions on Adult Health

  • Not only does in utero and childhood secondhand smoke exposure cause decreased lung function and asthma in children, but such exposure is also responsible for poor lung function and respiratory disease in adults. Men who report postnatal secondhand smoke exposure and women who report prenatal exposure are more likely to have respiratory problems as adults.
  • Secondhand tobacco smoke exposure raises adolescents' risk of metabolic syndrome - a disorder associated with excessive belly fat that increases one's chances of Heart disease, stroke, and type II Diabetes.
  • The level of secondhand smoke a child is exposed to is directly proportional to the likelihood of the child becoming a smoker as an adolescent or an adult.
  • Moderate exposure to tobacco smoke is associated with decreased elasticity of the abdominal aorta in healthy 11-year-old children. Altered aortic elasticity is an early marker of atherosclerosis.
  • SHS exposure in motor vehicles may be associated with nicotine dependence symptoms among young never-smokers.
  • Women exposed to six or more hours of secondhand smoke a day as children and as adults have a 68 percent greater chance of having difficulty conceiving and suffering more miscarriages.
  • There is an increased risk of failed embryo implantation among women reporting current secondhand tobacco smoke exposure.
  • In subjects hospitalized because of early wheezing, prenatal and postnatal secondhand smoke exposure is a risk factor for asthma in early adulthood. The connection between prenatal smoke exposure and asthma appears to be mediated via the development of bronchial hyper-responsiveness. Smoke exposure in infancy is associated with an increased risk of active smoking in early adult age, which in turn, is linked to current asthma.
  • The adverse effects of postnatal smoking on development of airway growth may persist into early adulthood.
