Media attention on the misuse of propofol increased significantly when the drug was implicated in the death of pop music superstar Michael Jackson in 2010. The misuse and abuse of propofol among healthcare providers has been reported worldwide, with some misuse resulting in death. Propofol policies guiding healthcare worker re-entry into the workplace after misusing propofol have received rare attention in the research literature. ⋯ This paper focuses on healthcare providers because they have an easy access to propofol and therefore are vulnerable to misusing or abusing the drug. To accomplish this, the pharmacology and misuse/abuse potential of propofol and the influence of the 12-step recovery paradigm in the re-entry literature are reviewed. In conclusion, existing research and policy are drawn upon to suggest employment re-entry guidelines for healthcare workers.

A new conditional reasoning measure was developed to evaluate the role of implicit biases in perpetuating addictive behavior. Data (N = 669) were collected in 2005 from two samples in a suburban area: individuals with a known history of chemical dependency and individuals from the general population. ⋯ Overall, findings suggest that addiction-prone individuals rely on a distinct set of cognitive biases that rationalize self-destructive behavior. The study's limitations are noted and implications and directions for future research are discussed.

Addiction films have been shaped by the internal demands of a commercial medium. Specifically, melodrama, as a genre, has defined the limits of the visual representation of addiction. Similarly, the process of intermedialization has tended to induce a metamorphosis that shapes disparate narratives with diverse goals into a generic filmic form and substantially alters the meanings of the texts. Ultimately, visual representations shape public perceptions of addiction in meaningful ways, privileging a moralistic understanding of drug addiction that makes a complex issue visually uncomplicated by reinforcing "common sense" ideas of moral failure and redemption.

Current trends in tramadol-related fatalities, Tehran, Iran 2005-2008.
Tramadol is a widely prescribed drug. Abuse of tramadol as well as tramadol-related deaths have been increasing in Iran. The objective of the present study is to evaluate the trends of tramadol-related deaths that occurred between 2005 and 2008 in Tehran, Iran. ⋯ The majority of the cases were young male adults. Tramadol-related deaths in 2008 were 32.5 times more than in 2005. These results suggest that tramadol-related fatalities are growing in Iran especially among substance abusers.

Noninvasive brain stimulation of the dorsolateral prefrontal cortex with repetitive transcranial magnetic stimulation and transcranial direct current stimulation can modify decision-making behaviors in healthy subjects. The same type of noninvasive brain stimulation can suppress drug craving in substance user patients, who often display impaired decision-making behaviors. We discuss the implications of these studies for the cognitive neurosciences and their translational applications to the treatment of addictions. We propose a neurocognitive model that can account for our findings and suggests a promising therapeutic role of brain stimulation in the treatment of substance abuse and addictive behavior disorders.
