Broad beneficial effects of cocaine abstinence reinforcement among methadone patientsK Silverman
Department of Psychiatry and Behavioral Sciences, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA
J Consult Clin Psychol 66:811-24. 1998..These results replicate the efficacy of cocaine abstinence reinforcement and show that it can have broad beneficial effects...
Opioid discrimination in humans: discriminative and subjective effects of progressively lower training doseK L Preston
Department of Psychiatry and Behavioral Sciences, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA
Behav Pharmacol 9:533-43. 1998..These data indicate covariation of subjective effects and discrimination performance and suggest that discrimination behavior may be more sensitive for differentiating among drug conditions than traditional subjective effects measures...

J Consult Clin Psychol 69:643-54. 2001..A 2nd phase of the study showed that abstinence induced by escalating-value vouchers can be maintained by a nonescalating schedule, suggesting that contingency management can be practical as a maintenance treatment...
Cocaine use early in treatment predicts outcome in a behavioral treatment programK L Preston

Monitoring opiate use in substance abuse treatment patients with sweat and urine drug testingM A Huestis
Chemistry and Drug Metabolism Section, National Institute on Drug Abuse Intramural Research Program, Baltimore, Maryland 21224, USA
J Anal Toxicol 24:509-21. 2000..However, the percentage of false-negative results, at least in this treatment population, indicates that weekly sweat testing may be less sensitive than thrice weekly urine testing in detecting opiate use...
Blockade of effects of smoked marijuana by the CB1-selective cannabinoid receptor antagonist SR141716M A Huestis
National Institute on Drug Abuse Intramural Research Program, 5500 Nathan Shock Dr, Baltimore, MD 21224, USA
Arch Gen Psychiatry 58:322-8. 2001..These findings suggest that CB1 receptors mediate many of the effects of marijuana, but this has not been evaluated in humans...
Family history influence on drug abuse severity and treatment outcomeR W Pickens

Drug Alcohol Depend 61:261-70. 2001..Both effects remained significant after adjusting for gender and race. These results suggest that common genetic factors may underlie both susceptibility to heroin dependence and response to therapeutic methadone treatment...

NIH, NIDA Intramural Research Program, Baltimore, Maryland, USA
Behav Pharmacol 10:531-42. 1999..Overall, the results support the sensitivity of the behavioral-testing procedure used, and show that 50 mg oral cocaine can serve as a discriminative stimulus in adult humans...
Naltrexone shortened opioid detoxification with buprenorphineA Umbricht
NIDA Intramural Research Program, Addiction Research Center, Baltimore, MD, USA
Drug Alcohol Depend 56:181-90. 1999..Peak withdrawal symptoms after naltrexone were of moderate intensity, suggesting that naltrexone combined with buprenorphine is an acceptable and safe treatment for shortened opioid detoxification and induction of naltrexone maintenance...

IRP, NIDA, NIH, Baltimore, Maryland 21224, USA
J Anal Toxicol 25:515-9. 2001..Increasing the opiate screening and confirmation cutoffs for the federal workplace drug-testing program resulted in 8% fewer opiate-positive tests; however, recent heroin use was not affected by this change...

Department of Psychiatry and Behavioral Sciences, Johns Hopkins University School of Medicine, Baltimore, Maryland
J Pharmacol Exp Ther 251:1053-63. 1989..o.; and secobarbital, 100-200 mg p.o.) did not generalize to hydromorphone, but showed partial generalization to both pentazocine and saline. In general, drug-discrimination performance paralleled the patterns of self reports...
