One can reduce the risk of Environmental tobacco smoke(ETS) by visiting places that are smoke-free.
Environmental tobacco smoke (ETS), or second-hand smoke, is the air polluted by tobacco smoke.
ETS consists of mainstream smoke (smoke exhaled from the smoker's lungs) and side stream smoke (smoke from the lit end of a cigarette, pipe, or cigar).
Conventional smoke exhaled by the smoker has a lower concentration of carcinogens, nicotine and tar. For this reason, side-stream smoke is more dangerous than mainstream smoke. ETS from tobacco, cigars, and pipes contain over 4,000 chemical compounds.
Over 50 of these chemicals are carcinogens. Several studies have shown that infants exposed to ETS are more likely to develop asthma than their unexposed peers. Inhaling ETS poses a serious health hazard.
Health Risks for Non-smokers
Second-hand smoke kills about 3,000 people each year from lung cancer. ETS causes eye irritation, headaches, ear infections, and coughing in people of all ages. It aggravates asthma and other respiratory disorders and increases the risk of coronary artery disease.

Answer:
Scoliosis can lead to osteoarthritis and degenerative changes in the spine, hips and knees. If a case is severe enough, internal organs may also be compromised or severely damaged.
Explanation:
The cause of physiological scoliosis is the human gait, which forces the spine into a threefold curve, alternately changing at every step. However, the innate normal asymmetries of the human body eventually establish permanent lateral curves of the spine, showing marked individual variations within the general law.
