The deadliest poison found in tobacco leaves is nicotine. While nicotine itself is not typically lethal in small doses, it is a highly toxic alkaloid that can be fatal in larger amounts. It affects the nervous system and can lead to respiratory failure or heart problems if ingested in significant quantities. Additionally, other harmful substances in tobacco smoke, such as tar and carbon monoxide, contribute to its overall toxicity and health risks.
