Boy or Girl? As if these health risks are not enough, smoking is now linked to stunted growth in adolescents and teens. BMI, or body mass index, measures body fat based upon height and weight. Boys who smoked 10 cigarettes a day between the ages of 12 and 17 grew about 1 inch shorter than nonsmoking boys 1. Despite the commonly held myth among teenage girls that smoking can control weight gain or even help them lose weight, the Canadian Cancer Society study found no difference in weight loss between girls who smoked and girls who did not.
Of the subjects who participated in the study, girls who smoked had similar BMIs to girls who did not smoke. However, a study in the February issue of the American Journal of Public Health reported a different health risk: Girls who smoke 10 cigarettes per day or more are at risk for abdominal obesity. Their waist sizes are 1. According to a study published in the Harvard University Gazette, adolescents as young as 10 have exhibited smoking-related lung damage.
Even as few as five cigarettes a day caused airway obstruction and delayed growth in lung functioning. The more an adolescent smoked, the greater the damage to lung capacity. Smoking thwarts bone growth in adolescence and adulthood. Smoking during adolescence is also a major risk factor in developing osteoporosis later in life 2.
Especially for girls, who already have an increased risk of developing osteoporosis, smoking can have detrimental effects on bone density.
For teenage and adult male and female smokers, decreased bone density can result in osteoporosis, arthritis and bone fractures. Fetal exposure to tobacco smoke results in lower birth weight and delayed development in infancy. Pregnant women should stay away from smokers.

Thank you I love this site. Unfortunately, there isn't much research available on the influence of smoking cigarettes on growth specifically. The dearth of information may be the result of research and medical ethics that prohibit exposing people to a substance with known health risks such as cigarettes to test the effects. As a result, any research is likely to only show a relationship between smoking and growth, but not necessarily prove that smoking is the cause.
Given the ethics at play, these studies likely used existing smoking and growth data to look for patterns, so the ability to draw conclusions is limited. They may be able to determine some of the causes and whether or not your growth will continue.
This finding may be best explained by a process called endochondral ossification in which bone replaces cartilage during fetal development. Since nicotine binds to the cells in bones that facilitate this process, it may impede bone growth. Another potential explanation for the connection of smoking on growth is rooted in the known effect of smoking on oxygen levels. All forms of smoking e. Ingesting carbon monoxide deprives cells of oxygen, which is necessary for cell growth and delivering nutrients to organs.
In studying several Himalayan populations living in high altitudes, the researchers discovered that they had shorter limbs and less blood flow. In contrast, what researchers have proven is that smoking can do significant damage to other areas of the body, including lung growth, respiratory function, and brain development.
