Active clinical trials for "Behavior, Addictive"

The Investigators hope to learn if they can prevent or lessen the symptoms of neonatal abstinence syndrome (NAS) in babies born to narcotic-dependent mothers by using the drug ondansetron in the mothers prior to delivery and their babies after delivery. The study is a randomized, double-blind, placebo-controlled study with one half the mother-baby pairs to receive ondansetron and the other half of the mother-baby pairs to receive placebo. The pregnant narcotic-dependent mothers will receive an intravenous dose of study medication prior to delivery; the neonates, after their birth, will receive the same study medication the mother received every 24 hours for up to 5 days. The Investigators will follow up with the mother-baby pairs for 10 days after study drug has stopped and one last follow up, about 30 days after stopping study drug, to learn if the baby had any symptoms of NAS in that time period.

The number of smartphone users in Taiwan continues to increase exponentially. Smartphone addiction tends to not only disrupt the ability of social communication but cause physical and psychological problems as well. This study examined the relationship among skin conductance, electroencephalography, heart rate variability (HRV), social interaction anxiety and smartphone addiction among Line apps users, and we also tried to identify associated factors for further interventions.

To evaluate addiction remission and addiction transfer after bariatric surgery.

Healthy adult human male facial skin surface lipid liquid pheromone given by mouth to opioid addicts cures them without any withdrawal symptoms whatsoever 250mg on chewing gum vehicle by mouth. Elevated mood eventually becomes accommodated after a few weeks. The pheromone contains volatile airborne sub-pheromones which cause aversive behavior (distrust, superstition, suspicion, arrogance, astonishment/stupidity, jealousy). Artificial jealousy can be avoided by patient isolation for 40 days until the pheromone "taste" wears off the saliva. The pheromone provided is odorless, colorless, and tasteless to the conscious brain.

The purpose of this study is to determine if extending the behavioral smoking-cessation treatment period to one year will significantly improve cessation outcomes among those planning a quit attempt.

This study is evaluating the efficacy of Treatment A for short-term smoking cessation through a blinded randomized controlled trial (RCT) vs.Treatment B.

Substance-using adults are admitted to hospital for medical complication from their drug and alcohol use at very high rates; yet, their care is often defined by low rates of referral to addiction treatment programs and recidivism. In 1997, we instituted an integrated medical-substance use treatment program at Johns Hopkins, the First Step Day Hospital, designed for intensive post-acute care of previously hospitalized substance using adults. We have shown that patients with dual diagnoses admitted to First Step more often complete their course of medical care and stay in recovery longer than patients not admitted to First Step.(1;2) On discharge from First Step, patients are medically stable and drug-free. Their substance abuse care is transferred to an out-patient substance abuse treatment facility and their medical care is transferred to their primary care provider. Unfortunately, many patients are lost to follow-up during this transition. We believe that a peer mentor-based disease management program (PM) can provide continuity of care that begins in First Step and continues after discharge thereby increasing the proportion of patients who remain in treatment for their addiction and medical conditions. Peer mentors are persons from the target community who have been in recovery for 5 or more years. In cooperation with patients and providers, peer mentors improve the integration of care, quality of care, and access to healthcare services. This pilot study will test the effectiveness of a peer mentor-based disease management program. The specific aims are to compare the impact of the PM intervention verses enhanced usual care on outcomes in three domains (1) medical/psychiatric health status, (2) addiction recovery, and (3) social resource acquisition. If successful, this study will provide evidence supporting a larger randomized controlled trial of the impact of field workers on post-acute care among patients with dual diagnoses.

In this study, the investigators are looking at how people make decisions about reward-related items, both monetary and food related after taking either the dopamine agonist bromocriptine or the COMT inhibitor tolcapone, in healthy control subjects. Subjects will fill self-report questionnaires and undergo an MRI scan.

Addiction is known as a chronic relapsing brain disorder that has a high cost to patients, family and society. Its ranking in cause of death is 8th globally, and substance abuse contributes 5.4% of the total global burden of disease. Brain stimulation procedures such as repetitive trans-cranial magnetic stimulation (rTMS) and trans-cranial direct current stimulation (tDCS) are considered minimal risk interventions and are used for the treatment of depression, pain, and other neurological and psychiatric disorders. There is some evidence that rTMS applied to the left prefrontal cortex results in significantly lowered craving. To date, no studies have investigated the effects of a course of either rTMS or tDCS treatment on opioid craving, brain function, and relapse prevention in opioid addicts. Individuals with prescription opioid dependence experience high rates of desire and intense cravings to use opioids. The present study aims to examine the effects of a course of daily prefrontal rTMS and tDCS on brain function, desire and craving and help to relapse prevention in abstinence phase.

Background: - Varenicline (Chantix ) is a drug that is approved by the Food and Drug Administration (FDA) to help people stop smoking. Varenicline is very effective in helping some people quit smoking, but is less effective for others. Researchers are interested in conducting more in-depth studies into how varenicline works, including its effect on smokers' responses to items that may trigger cigarette cravings, in order to develop better smoking cessation medications. Objectives: - To examine the effectiveness of varenicline as an effective medication for tobacco addiction by studying its effect on nicotine reinforcement, nicotine-seeking behavior, cue-elicited craving, and performance impairment and craving after overnight tobacco deprivation. Eligibility: - Individuals between 18 and 50 years of age who have been smoking at least 10 cigarettes per day for at least 2 years. Design: This study will require 12 study visits. Some visits will be brief and other visits that involve test sessions will last up to 8 hours. If no sessions are repeated, the study will take 26 days. Participants will not be required to attempt to quit smoking during this study. Participants will be screened with a full physical examination and medical history, blood and urine tests, and other tests as required by the study researchers. Participants will take two sets of pills during the study: the first set during the first 12 days of the study, followed by a 2-day break, then the second set during the last 12 days. Some of the pills will contain varenicline, and others will be placebos. On Day 1 of the study, participants will come to the National Institute on Drug Abuse to receive the first set of pills. Participants will take the first pill before leaving. On Day 8, participants will have a training session that will measure the amount of carbon monoxide in the breath. Participants will also complete several questionnaires about smoking habits and current mood, and will have a chance to practice the procedures they will do in the study. On Days 9 and 10, participants will have behavioral test sessions that will last 7 to 8 hours. Day 9 will involve tests of cue response to items that may trigger cigarette cravings, and tests of general nicotine cravings over several hours. Day 10 will involve tests of general nicotine cravings over several hours, and then tests of nicotine-seeking behavior. Participants will be provided with lunch during these all-day sessions. On Day 11, participants will have memory and attention tests, and will provide a blood sample. Participants will not be allowed to smoke for 12 hours before the start of the next test on Day 12. On Day 12, participants will provide a breath sample, and will have two sets of memory and attention tests before they will be permitted to start smoking again. There will be no tests on Days 13 and 14. Starting on Day 15, participants will repeat the schedule of tests from Days 1 through 12 with the second set of pills.
