Some biological psychologists suggest that nicotine addiction is best understood through neurochemical mechanisms, such as the activation of nicotinic acetylcholine receptors (nAChRs) and subsequent dopamine release in the mesolimbic pathway. However, other psychologists argue that environmental factors, including operant conditioning and social modelling, offer a more comprehensive explanation for why people start and continue smoking.
Evaluate biological and environmental explanations of nicotine addiction with reference to the views described above.
