We here review experimental findings relevant for the pharmacology of conscious experience, an issue largely neglected in pharmacological research. First, we focus on self-awareness, a pivotal component of conscious experience and its integration within the global neuronal network (GNW), a theoretical concept that unifies convergent approaches on the neural bases of conscious processing. We...
Purpose Existing treatments for alcohol and substance dependence are of limited efficacy and acceptability to users. Since such dependence is associated with high co‐morbidity and mortality rates, alternative treatments should be urgently evaluated. Ibogaine, a hallucinogenic alkaloid, derived from Tabernanthe Iboga, a plant unique to the rainforests of West Africa, is already associated with a...
The default mode network (DMN) is a set of brain regions that consistently shows higher activity at rest compared to tasks requiring sustained focused attention toward externally presented stimuli. The cognitive processes that the DMN possibly underlies remain a matter of debate. It has alternately been proposed that DMN activity reflects unfocused attention toward external stimuli or the...
Although work-site factors have been shown to be a consistent predictor of burnout, the importance of mindfulness and values-based processes among addiction counselors has been little examined. In this study, we explored how strongly experiential avoidance, cognitive fusion, and values commitment related to burnout after controlling for well-established work-site factors (job control, coworker...

Individuals with Binge Eating Disorder (BED) often evidence comorbid Substance Use Disorders (SUD), resulting in poor outcome. This study is the first to examine treatment outcome for this concurrent disordered population. In this pilot study, 38 individuals diagnosed with BED and SUD participated in a 16-week group Mindfulness-Action Based Cognitive Behavioral Therapy (MACBT). Participants...

Marijuana (Cannabis sativa) is the most commonly used illicit drug worldwide as well as in the Unites States. Prolonged use of marijuana or repeated administration of its primary psychoactive constituent, Δ9-tetrahydrocannabinol (THC), can lead to physical dependence in humans and laboratory animals. The changes that occur with repeated cannabis use include alterations in behavioral,...
Cannabis has been associated with transient psychotic states; however, the causal relationship between cannabis and schizophrenia continues to remain a matter of debate. Epidemiological and some biological studies hint at cannabis being an independent risk factor for schizophrenia; this has not been definitively proved. We aimed to understand the patterns of glucose uptake in important brain...
Ketamine was developed in the early 1960s as an anesthetic and has been used for medical and veterinary procedures since then. Its unique profile of effects has led to its use at subanesthetic doses for a variety of other purposes: it is an effective analgesic and can prevent certain types of pathological pain; it produces schizophrenia-like effects and so is used in both clinical studies and...
