Overview
Nicotine is a highly effective cognitive enhancer in terms of attention and reaction time. However, it is also highly addictive, which significantly limits its suitability as a nootropic for general use. While it demonstrates strong acute cognitive benefits, the risk profile outweighs its utility for most individuals seeking sustainable cognitive optimisation.
