Age Differences in the Vulnerability to Nicotine Addiction:

Rapid delivery of nicotine promotes behavioral sensitization and alters its neurobiological impact.

BACKGROUND Nicotine is highly addictive when it is inhaled from tobacco smoke, whereas nicotine replacement products, which usually deliver nicotine orally or transdermally, rarely lead to addiction. It has been proposed that this is due in part to differences in the rate of nicotine delivery to the brain under the two conditions. However, the mechanism by which rapid nicotine delivery facilita...

Does a reduced sensitivity to bitter taste increase the risk of becoming nicotine addicted?

Cigarette smoking appears to be on the increase in adolescents. The initiation of regular smoking nearly always begins before adulthood. It is therefore crucial to find ways of identifying those children most vulnerable to nicotine addiction and prioritizing them for preventive measures. We hypothesized that individuals who, in a simple taste test, perceive phenylthiocarbamide (PTC) as bitter m...

Molecular Mechanisms Underlying Environmental Enrichment-Induced Neuroprotection in Vulnerability to Nicotine Addiction

Cortisol secretion patterns in addiction and addiction risk.

Addiction to alcohol or nicotine involves altered functioning of the brain's motivational systems. Altered functioning of the hypothalamic-pituitary-adrenocortical (HPA) axis may hold clues to the nature of the motivational changes accompanying addiction and vulnerability to addiction. Alcohol and nicotine show at least three forms of interaction with HPA functioning. Acute intake of both subst...
