Which of the following effects is associated with nicotine consumption?

Nicotine consumption is known to have several stimulating effects on the body and brain, one of which is the potential for heightened cognitive function. When nicotine is consumed, it acts on nicotinic acetylcholine receptors in the brain, leading to increased release of several neurotransmitters, including dopamine, norepinephrine, and acetylcholine. This neurotransmitter release can enhance alertness, attention, and cognitive processing speed.

Research shows that nicotine has been associated with improved performance on tasks requiring attention and working memory, suggesting that it can stimulate certain cognitive functions. The ability to enhance focus and concentration makes nicotine appealing to some individuals, particularly in contexts that demand mental exertion.

Contrastingly, effects such as weight gain, increased appetite, and increased fatigue are usually not associated with nicotine use. In fact, nicotine tends to suppress appetite and often leads to weight loss for some individuals, making these options less aligned with the known pharmacological effects of nicotine.
