What is the pH of cigarette smoke?

Cigarette smoke is generally mildly acidic (pH 5.6-6.3), and thus requires inhalation for efficient absorption of high doses. Mildly acidic smoke is also generally less noxious to inhale than alkaline smoke (Brunnemann & Hoffman, 1974).

Is nicotine on its own harmful?

Does nicotine affect intelligence?

For example, compared to healthy controls, cigarette smokers have cognitive deficits in auditory–verbal and visuospatial learning, visuospatial memory, cognitive efficiency, executive skills, general intelligence, and processing speed (large effect sizes, d ≥ 0.8) [29].

Does nicotine affect mood?

At first, nicotine improves mood and concentration, decreases anger and stress, relaxes muscles and reduces appetite. Regular doses of nicotine lead to changes in the brain, which then lead to nicotine withdrawal symptoms when the supply of nicotine decreases.
