Post-traumatic Stress Disorder (PTSD), Addiction, and Virtual Reality
Substance Use DisordersPosttraumatic Stress DisorderEligible veterans, National Guardsmen & Reservists with post-traumatic stress disorder (PTSD) and problems with addiction will be randomly assigned to one of two treatment conditions. All participants will undergo exposure therapy, a gold standard behavioral treatment for PTSD for 10 weeks. In addition to exposure therapy, some participants will be randomly assigned to receive (1) virtual reality (VR)-based exposure to cues for marijuana, cocaine, heroin, cigarette, and/or alcohol use, and (2) cellular phone-based reminders of learning (extinction reminders, or, ERs) to VR exposure (available 24 hours per day/7 days per week) to high-risk contexts for drug use. The main hypothesis is that those participants who receive exposure therapy + VR/ERs will demonstrate less substance use and lower PTSD symptoms during treatment, at post-treatment, and at follow-up than those participants who only receive exposure therapy. At study completion, a total of 123 subjects signed consent.
Integrative Meditation (IM) for Cocaine Addiction
Cocaine AddictionCocaine addiction continues to be a major problem in the U.S. with no FDA-approved pharmaceutical therapy. Finding effective treatment for cocaine addiction has long been a challenge to scientists and clinicians. Psychosocial interventions known as behavior therapies are the cornerstone of cocaine addiction treatment. However, there is an urgent need to further improve treatment outcomes, especially during early recovery and the protracted withdrawal phase of the treatment since many patients drop out or relapse during this phase. Our clinical experience and studies suggest that integrative Meditation (IM) helps reduce cravings and withdrawal symptoms and increases treatment retention. The benefit of IM is well supported by tension-reduction theory and attention-networks framework in addiction treatment. The proposed study will implement a therapy development study to add IM as a self-care component to the current outpatient treatment of cocaine addiction to improve treatment outcomes. The specific aims of the proposed study include: 1) to conduct a 12-week controlled trial with outpatient cocaine users to assess feasibility of recruiting and retaining cocaine addicts and to determine effect size of IM-augmented treatment in comparison with Nondirective Therapy (NT) control, with both groups receiving standard outpatient treatment as usual (TAU), thereby facilitating future larger scale therapy development study; and 2) to examine the changes in attention networks and negative mood as possible mediators of treatment outcomes between the two groups.
Enhancing Disrupted Reconsolidation: Impact on Cocaine Craving
Cocaine AddictionThe investigators' recently completed study has provided the first evidence that administration of the medication propranolol, following exposure to cocaine cues, can alter drug-associated memories and reduce craving and other drug cue-elicited responses in cocaine addicted persons. The investigators will attempt to augment this effect by a) doubling the number of propranolol-medicated cocaine cue exposure (CCE) retrieval sessions and b) increasing the dose of propranolol. It is expected that propranolol treated groups, relative to placebo treated groups, will evidence greater reduction of craving, cue reactivity and cocaine use during follow-up cocaine cue exposures. Also, these effects will be greater for those who receive 80mg of propranolol as opposed to 40mg.
Efficacy and Safety of BP1.4979 in Smoking Cessation
Tobacco AddictionClinical study which aim is to assess in heavy smokers willing to quit smoking the efficacy and the safety profile of BP1.4979 for smoking cessation on the total abstinence measured by subject diary and confirmed by exhaled CO (abstinent < 10 ppm).
Cognitive Behavioral Therapy (CBT) for Posttraumatic Stress Disorder (PTSD) in Community Addiction...
Stress DisordersPost-Traumatic1 moreThe purpose of this phase of the study is to assess the efficacy of CBT for PTSD, as delivered by routine addiction counselors in community treatment programs, and to compare CBT for PTSD with both Individual Addiction Counseling (IAC) and Treatment as Usual (TAU) on the primary outcomes.
Malmö Treatment Referral and Intervention Study
Heroin AddictionSubstance Use DisordersThis study aims to study and implement active referral of heroin users from a syringe exchange programme to evidence-based treatment for heroin addiction. Patients are randomized to either a strength-based case management intervention or a control group, while both groups receive referral to medical investigation for inclusion in substitution treatment for heroin addiction. The hypothesis is that syringe exchange can be used for referral to effective treatment, and that a strength-based intervention can increase the number of patients who are successfully referred and enter treatment.
Effects of Random Nicotine Delivery on Smoking Cessation
Smoking CessationCigarette Smoking1 moreThe objective of this study is to determine whether treatment with random nicotine delivery via a nicotine film both before and after the target quit date will facilitate smoking cessation relative to treatment with steady state delivery or placebo. The investigators hypothesize that smoking cessation will be greater in subjects assigned to a random nicotine delivery regimen (as compared to those assigned to a steady state or placebo regimen). The nicotine film product is not part of the standard of care and is not available in non-investigational settings in the United States.
Evaluation of the Efficacy of Repetitive Transcranial Magnetic Stimulation (rTMS) Low-frequency...
Smoking CessationAddictionThe fight against smoking is a public health priority. Without help, fewer than 5% of des smokers are abstinent at 12 months after smoking cessation. Despite well-managed attempts at smoking cessation with nicotine substitutes, the rate of success at 12 months in patients dependent on nicotine is only 18%. Moreover, other therapeutic strategies (acupuncture, hypnosis…) have not proved to be effective. The investigators propose a new therapeutic strategy for smoking cessation, which is based on associating nicotine substitutes (to reduce physical symptoms of weaning from nicotine) with rTMS at 1 Hz to the right DorsoLateral PreFrontal Cortex (DLPFC) for 2 weeks (to diminish craving for tobacco). The principal objective is to improve the success rate for smoking cessation attempts in patients who are highly dependent on nicotine, and who have failed using usual smoking cessation strategies.
Effects of tDCS on Craving, Relapse and Cognitive Functions Among Patients With Cocaine Use Disorder...
Cocaine AddictionRepetitive bilateral (left cathodal/ right anodal) transcranial Direct Current Stimulation (tDCS) over the dorsolateral prefrontal cortex (DLPFC) reduces craving and seems to decrease relapse risk in addiction. However, little is known about the relapse rates in cocaine addiction after tDCS, despite the need for neurobiological treatments to reduce the high relapse rates in this population. The current study explores the effects of repetitive tDCS in a larger sample (N=60) of cocaine addicted patients on number of relapse days after three months. We expect that a decrease in relapse risk after tDCS is associated with cognitive control functioning. Therefore, risky decision making and inhibitory control will be measured before and after the interventions, and at three months follow-up. Ecological momentary assessment (EMA) will be used as a reliable measure for relapse, craving and mood.
Theta Burst TMS as a Tool to Change Smoking Behavior
SmokingAddictionThe goal of this study is to determine whether transcranial magnetic stimulation (TMS) is an effective treatment in decreasing craving in individuals who habitually smoke cigarettes. The study consists of six total visits to MUSC; one for the consent process, two that will include MRI scans, and five that will include TMS administration. Compensation will be provided for each visit.
