Evidence suggests that research participants often fail to recall much of the information provided during the informed consent process. This study was conducted to determine the proportion of consent information recalled by drug court participants following a structured informed consent procedure and the neuropsychological factors that were related to recall. Eighty-five participants completed a standard informed consent procedure to participate in an ongoing research study, followed by a 17-item consent quiz and a brief neuropsychological battery 2 weeks later. Participants performed (...) within the normal range on most of the neuropsychological measures, although roughly one third showed deficits on measures of executive functioning. Participants failed to recall over 65% of the consent information within 2 weeks of entering the study, and their recall was significantly correlated with verbal IQ, drug problem severity, reading ability, memory, and attention. These factors may be useful in determining whether research participants require enhanced consent procedures. (shrink)

There is mounting evidence that methylphenidate (MPH; Ritalin) is being used by healthy college students to improve concentration, alertness, and academic performance. One of the key concerns associated with such use of pharmaceuticals is the degree of freedom individuals have to engage in or abstain from cognitive enhancement (CE). From a pragmatic perspective, careful examination of the ethics of acts and contexts in which they arise includes considering coercion and social pressures to enhance cognition. We were interested in understanding how (...) university students, parents of university students, and healthcare providers viewed autonomy and coercion in CE using MPH. We found that perspectives converged on the belief that CE is a matter of personal and individual choice. Perspectives also converged on the existence of tremendous social pressures to perform and succeed. Parents emphasized personal responsibility and accountability for CE choices, and expressed feelings of worry, sadness and fear about CE. Students emphasized the importance of personal integrity in CE, expressed tolerance for personal choices of others, and highlighted the challenge that CE poses to maintaining one’s personal integrity. Healthcare providers emphasized the health consequences of CE. These results illustrate: (1) the importance of understanding how context is viewed in relation to perspectives on autonomous choice; (2) the limitations of individualistic libertarian approaches that do not consider social context; and (3) the ethical implications of public health interventions in a value-laden debate where perspectives diverge.

This paper is a survey of the positive and negative aspects of cannabis use from the point of view of the individual on one hand and from the point of view of the society on the other hand. Health, social, and political motives are all discussed, and the best method of harm reduction is analysed. The upshot is that zero tolerance policy is obsolete, and that most individuals would be better off using cannabis rather than other drugs.
