The result is a prolonged activity of pleasurable substances that are released in the brain under the influence of nicotine, such as dopamine and serotonin. The most plausible mechanism of action at work here is based on inhibition of the enzyme called monoamine-oxidase (MAO), active in brain nerve cells, where it is responsible for breaking down neurotransmitters. Furthermore, the effect is actually strongest in young animals. Studies show that when acetaldehyde is absorbed with nicotine it reaches the brain, and has a more powerful (synergistic) effect – i.e., one substance increases the activity of other, so when combined, these substances’ effect is more powerful than just the sum of their effects alone:Ĭontrolled studies in rats (using an established animal model for tobacco addiction) showed a mixture of nicotine with a small amount of acetaldehyde causes a much stronger addiction than nicotine by itself the rats consumed more nicotine compared to when they were given just ‘pure’ nicotine. Sugar mixture – Beyond their stated effect on the taste, helping to mask nicotine’s bitterness, heated and burnt sugars emit a substance called acetaldehyde and cigarette smoke is indeed rich in acetaldehyde. Is this a coincidence? Judge for yourself: The tobacco companies argue that the components are designed to enhance the taste of the cigarette, reviewing the list of ingredients shows that many of the components that are added act on the human body or on the nicotine itself to strengthen its effect, as explained in detail below.

But it is a mistake to consider cigarettes a ‘natural’ product. The main ingredient in cigarettes is tobacco – a plant that contains, among other things, a relatively high concentration of a chemical called nicotine, which is the active and addictive compound in cigarettes. ![]()
