Nicotine commonly found in cigarettes is actually produced by plants as a natural protectant to safeguard from insects. It resembles the acetylcholine neurotrasmitter as thus blocks the ACH receptors when used by humans. It also stimulates the production of dopamine which leads to drug dependence and a feeling of euphoria.Severe withdrawal symptoms are observed for nicotine. Peer review refers to the work done during the screening of submitted manuscripts and funding applications. This process encourages authors to meet the accepted standards of their discipline and reduces the dissemination of irrelevant findings, unwarranted claims, unacceptable interpretations, and personal views. Publications that have not undergone peer review are likely to be regarded with suspicion by academic scholars and professionals.
