Another thing about smoking is that it affects physiological processes and makes it a challenge for them. Things like respiration for example.
Smoking really affects your lungs because it interferes with respiration
Smoking is sometimes exhilarating and relaxing although bad for your health. Yea, the smoke is actually absorbed into the bloodstream The nicotine is what is addicting. The bloodstream moves quickly. Smoking creates these heated aerosol as well as gas that gets in the lungs. The bloodstream then absorbs the substances. There is definetly a line of order in the way the body absorbs the smoke. Interesting. In some cultures smoking is used to induce trances and spiritual enlightenment WOW. That is very cool. You learn something new everyday.
Smoking generally has negative health effects, because smoke inhalation inherently poses challenges to various physiologic processes such as respiration.
