What is a common effect of nicotine found in cigarette smoke?

1. It creates a sense of relaxation

2. It causes addiction to smoking

3. It increases metabolism

4. It improves concentration instantly

The correct answer is: It causes addiction to smoking

The choice that identifies the common effect of nicotine found in cigarette smoke is that it causes addiction to smoking. Nicotine is a highly addictive substance, and its presence in tobacco products like cigarettes leads to physical and psychological dependence among users. When nicotine is inhaled, it rapidly reaches the brain, leading to the release of neurotransmitters like dopamine, which creates pleasurable sensations. Over time, regular use results in the body's adaptation to nicotine, requiring increased consumption to achieve the same effects, thus reinforcing the cycle of addiction. While nicotine can produce sensations that may seem relaxing or enhance concentration temporarily, these effects are often short-lived and followed by withdrawal symptoms that can lead individuals back to smoking. The idea that nicotine increases metabolism is not universally accepted as a common effect since it can vary by individual and is not the primary reason people continue to use tobacco products. Understanding the addictive nature of nicotine is crucial, as this drives smoking behavior and makes cessation challenging for many individuals.
