Which of the following statements is FALSE? Nicotine is a powerful psychoactive drug. Nicotine is highly addictive. Nicotine is considered a powerful depressant. Nicotine affects one's mood.

The correct answer is Nicotine affects one's mood.

Nicotine is an organic compound from the group of alkaloids, which are heterocyclic amines, that is, which have closed chains (cycles), containing a nitrogen.

It is produced by burning cigarettes and is the main cause of addiction that smokers have. This is because when you smoke your cigarette, nicotine reaches the brain in about 9 seconds and acts on the central nervous system, causing a pleasant feeling of well-being. However, this sensation is fleeting and the more the person smokes the more the body adapts to the drug and the addiction increases, requiring more doses of nicotine in the body, that is, increasing the amount of cigarettes consumed. That is why when someone tries to stop their addiction, suddenly stopping their smoking, they usually have a withdrawal syndrome.

In addition, at the time of consumption, nicotine also causes a stimulating action in the central nervous system and, as a consequence, there is an increase in blood pressure, heart rate, respiratory rate and motor activity, in addition to reduced appetite .
