Answer :

The toxic substance that gives tobacco products their addictive quality is called nicotine. Nicotine is a chemical compound found in tobacco products such as cigarettes and cigars. It acts as a stimulant and increases heart rate, blood pressure, and respiration. Nicotine is highly addictive because it causes the release of dopamine, the brain’s pleasure hormone. It also causes physical dependence, making it difficult for people to quit smoking.

Nicotine is a psychoactive chemical found in tobacco products, and it is responsible for their addictive quality. It is an alkaloid found in the nightshade family of plants, which includes tomatoes, potatoes, and eggplants.

Nicotine binds to cholinergic receptors in the brain, releasing a neurotransmitter called dopamine. This neurotransmitter is associated with reward and pleasure, and it is what gives nicotine its addictive quality.

When nicotine is ingested, it causes a temporary increase in blood pressure and heart rate. It also increases levels of adrenaline and cortisol, two hormones associated with stress. The combination of these effects can lead to feelings of alertness, relaxation, and pleasure.

The effects of nicotine, however, are short-lived. The body quickly begins to develop a tolerance to nicotine, meaning that more of the substance is needed to achieve the same effects. This can lead to addiction and withdrawal symptoms when the person stops using nicotine.

Nicotine is a very dangerous substance. It can lead to serious health problems, including cancer, heart disease, and stroke. It can also increase the risk of developing a mental health disorder, such as anxiety and depression.
