The most prevalent motives given for illicit use of prescription stimulants were to help with concentration, increase alertness, and provide a high, and the authors found no gender differences in motives.
Illicit Methylphenidate Use in an Undergraduate Student Sample: Prevalence and Risk Factors
Study Objectives. To assess the prevalence of illicit methylphenidate use among undergraduate college students at a large university, and to identify alcohol and other drug use behaviors, as well as…
Smoking Modulation of μ-Opioid and Dopamine D2 Receptor-Mediated Neurotransmission in Humans
The data point to both the feasibility of simultaneously examining opioid and DA neurotransmission responses to smoking in humans, as well as to the need to examine non-nicotine aspects of smoking to more fully understand the behavioral effects of this drug.
Regional cerebral blood flow responses to smoking in tobacco smokers after overnight abstinence.
Smoking affects rCBF not only in areas of the brain rich in nicotinic cholinergic receptors but also in areas implicated in the rewarding effects of drugs of abuse, including the nucleus accumbens.

Correlations with arterial nicotine on rCBF were statistically significant in brain areas with the greatest changes in relative blood flow such as the cerebellum and occipital cortex, which contribute to changes in r CBF.
A Comprehensive Review of MDMA and GHB: Two Common Club Drugs
Health care professionals must be familiar with these substances and the treatment options for patients who present with symptoms of a toxic reaction and the pharmacokinetics of MDMA and GHB appear to be nonlinear.
Regional cerebral blood flow effects of nicotine in overnight abstinent smokers
In habitual smokers after overnight abstinence, nicotine induced differing effects on regional blood flow relative to whole brain blood flow, including increases in the thalamus, a region rich in nicotinic receptors, and reductions in limbic and paralimbic regions.

Level of work performance was generally associated with severity of anxiety, and of the instruments tested, the WLQ and the WPAI questionnaire demonstrated acceptable validity and internal reliability.
Effects of nicotine on regional cerebral glucose metabolism in awake resting tobacco smokers
Nicotine caused a small overall reduction in global cerebral metabolism of glucose but, when the data were normalized, several brain regions showed relative increases in activity and this is consistent with the high density of nicotinic cholinoceptors in that brain region.
Venous plasma nicotine correlates of hormonal effects of tobacco smoking
The present study resolves some of the discrepancies in the literature by correlating the effects of tobacco smoking on hormone release with venous plasma nicotine levels by quantifying the well known increase in plasma cortisol and prolactin after nicotine postsmoking with peak plasma levels up to 35 ng/ml.
