Globally, more than a billion people are addicted to nicotine, and more than 100 million are addicted to alcohol.
The nightshade family of plants naturally generate the alkaloid nicotine, which is extensively used recreationally as a stimulant and anxiolytic. Within seconds after inhaling nicotine, it reaches the brain. Nicotine enhances the release of neurotransmitters, brain chemicals that help control mood and behaviour.
Alcohol, often known by its chemical name ethanol, is a psychoactive substance found in alcoholic beverages like beer, wine, and distilled spirits.
Alcohol can change how the brain functions and looks by interfering with the brain's communication networks.

<h3>Briefing:</h3>
HeLa cells are malignant cells rather than normal cells. In normal cells, chromosomes have telomeres at their ends, which shrink after each cell division. The cell enters senescence when its telomeres reach a certain length. Telomere shortening is hence the cause of cellular senescence.
Telomerase is continuously produced and expressed in HeLa cells. Telomerase is an enzyme that prevents telomere shortening and therefore also cellular aging.
