Nicotine, one of the stimulant substances that everyone has met at least once in their life, can be taken by the respiratory system, even through cigarette smoke. Nicotine dependence, which the World Health Organization (WHO) considers to be one of the most difficult addictions, is unfortunately seen in many people in society. Due to the temporary feeling of comfort, the choice of nicotine as a mind opener and advocacy of being used by humans for this purpose is extremely misleading.

The carbon monoxide gas is a colorless, tasteless, odorless, flammable, toxic gas. It could even leak from the walls. It enters the body through the respiratory tract. Carbon monoxide is not destroyed in the body, it is expelled by respiration. Carbon monoxide poisoning often occurs during burning in a closed environment (such as water heaters, stoves, stoves) and may also occur in the business lines where carbon monoxide is used or produced. If poisonings that occur with respiratory poison carbonmonox are not medically intervened in a short time, poisoning may end with death.

It was brought to the Ottoman empire from day to day, through various exchanges, as long as it looked old. This change is not the content of the tar, but the change in the ease of obtaining.
