What is the main psychoactive ingredient in tobacco products?

Explanation:
Nicotine is the primary psychoactive component in tobacco products. It acts on nicotinic acetylcholine receptors in the brain, leading to increased dopamine release in reward-related pathways and producing the reinforcing effects that drive tobacco dependence. While caffeine, THC, and ethanol are also psychoactive substances, they are not the main addictive agents in tobacco—caffeine is the stimulant in coffee/tea, THC is the primary psychoactive in cannabis, and ethanol is the intoxicating component of alcoholic drinks. This is why nicotine best fits as the main psychoactive ingredient in tobacco products.
