Plants are credited for the production of different drugs in the world (Wong, 2014). Most plants produce defensive chemical compounds that enable protect them from insects and animals. Cocaine, nicotine, caffeine and morphine are good examples of chemical compounds extracted from plants. Nicotine is a chemical compound that contains alkaloids and enables the manufacture of neurotoxin drugs. Nicotine is found in tobacco plants. According to Herkewitz (2014), a more delicate and less toxic offensive approach is used by nicotine in protecting the tobacco plant. Alkaloids, which are produced by the tobacco plant and are contained in nicotine, alter the concentration of chemicals in the brain. At higher levels, the compound can kill insects or overdose a person.
The compound also enables pollination in the tobacco plants. The plants depend on animals and insects for pollination and breeding. Therefore, a more friendly approach is used by the plant to enable this. Nicotine being a less harmful compound for animals and insects is produced to enable stimulate the mind of the users without harming them in anyway. However, an overdose can be dangerous for the humans and insects. Nicotine, therefore enables enhance pollination in tobacco plants because of its stimulating effect caused by alkaloids, in the brain of animals and insects.

Humans can be addictive to nicotine. The human brain differs from the insect’s brain despite functioning in the same way. However, the brain effects of nicotine differ between humans and insects. Unlike insects which find the compound repulsive, humans find pleasure in the compound (Herkewitz, 2014). This is because the human brain has structures that are responsible for providing pleasurable effects and sensations. The compound intensifies dopamine in human. Dopamine is a neurotransmitter in the human brain. These intensified activities of dopamine are the implications of addiction and the pleasurable sensation of nicotine.
