Beginning with a detailed look at individual drugs and their effects on the brain, Neurochemistry of Abused Drugs considers the changes in neurotransmitter levels and discusses the relationship of these changes to the nature and phenomenon of addiction. New studies highlight the addictive capacity of nicotine as well as introduce novel compounds that may aid in tobacco cessation. Chapters examine nicotine dependant neuroplasticity and the various neurochemical substrates that support and promote addiction including cholinergic, dopaminergic, and GABAergic adaptations. The book also offers detailed information on the neurochemical and neurobehavioral consequences of MDMA, methamphetamine, and cocaine use. Recent discoveries on the neurotransmitter systems involved in each of these drugs reveal new therapeutic targets for alleviating addiction including ibogaine, and GABA and glutamate receptors. Extensively referenced and citing numerous up-to-date studies, this book provides unparalleled insight into the action and potential inhibition of drugs of abuse.
