There is evidence that visual stimuli used to signal drug delivery in self-administration procedures have primary reinforcing properties, and that drugs of abuse enhance the reinforcing properties of such stimuli. Here, we explored the relationships between locomotor activity, responding for a visual stimulus, and self-administration of methamphetamine(More)
We recruited a sample of university student gamblers (n = 48) to complete a web-based battery of instruments in a study designed to assess the impact of imagery-based versus photographic cue exposure on acute craving to gamble using the multi-item Gambling Urge Scale (GUS; Raylu and Oei 2004). Although self-reported craving increased following both forms of(More)
The term "sensory reinforcer" has been used to refer to sensory stimuli (e.g. light onset) that are primary reinforcers in order to differentiate them from other more biologically important primary reinforcers (e.g. food and water). Acquisition of snout poke responding for a visual stimulus (5 s light onset) with fixed ratio 1 (FR 1), variable-interval 1(More)
Although the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) does not explicitly list craving as a diagnostic criterion for pathological gambling, theories of disordered gambling and research on relapse precipitants suggest that cravings--among other factors--provoke and maintain episodes of gambling. Assessment of craving to gamble(More)
Understanding sensory reinforcement and the effects of stimulant drugs on sensory reinforcers is potentially important for understanding their influence on addiction processes. Experiment 1 explored the reinforcing properties of a visual stimulus and the effects of methamphetamine (METH) on responding maintained by a visual reinforcer (VRF) in male rats.(More)
OBJECTIVE This study was designed to assess non-medical prescription opioid use among a sample of opioid dependent participants. METHODS A cross-sectional survey was conducted with a convenience sample of patients hospitalized for medical management of opioid withdrawal. We collected data related to participant demographics, socio-economic(More)
When prescribing opioids to treat chronic pain, physicians face the dilemma of balancing effective pain management while avoiding iatrogenic opioid addiction. Through mailed surveys, the current study assessed concerns, perceptions, and practices of primary care physicians related to this dilemma. Of the 35 (43%) physicians that replied, 32 (91.4%) reported(More)
OBJECTIVES Effective strategies are needed to manage individuals with chronic non-cancer pain and coexistent opioid addiction. This study compared opioid discontinuation and opioid replacement protocols. METHODS We planned to enroll 60 individuals into an open-label trial who had been treated with opioids for chronic non-cancer pain, and who also had(More)
BACKGROUND The abuse of synthetic cannabinoids has emerged as a public health concern over the past few years, yet little data exist characterizing the use of synthetic cannabinoids, particularly among patients seeking substance use disorder (SUD) treatment. In a sample of patients entering residential SUD treatment, we examined the prevalence of and(More)
Participants (n=150), undergoing inpatient alcohol detoxification, were randomized into 3 groups: treatment as usual (TAU), motivation enhancement therapy (MET), or peer-delivered 12-step facilitation (P-TSF). The main outcome was the initiation of any type of subsequent rehabilitation service (i.e., professional treatment or self-help) within 30 and 90(More)
