Causes of death among crack cocaine users

Abstinence trajectories among treated crack cocaine users.

This article reports findings from a study that investigated treatment outcomes among crack/cocaine users over a 18-month period. From a cohort of 229 subjects, three groups emerged: (1) those who had reported ongoing, stable abstinence from crack/cocaine; (2) those who had consistently used during the period; and (3) those who reported cycling between abstinence and use during the follow-up pe...

Accumbens volumes are reduced among crack-cocaine users

The brain reward system is known to be the neuroanatomical basis of addictive behaviors. Systemic, cognitive and functional consequences of crack-cocaine addiction are clinically evident, but the neuroanatomical underpinnigs are not yet well understood. We aim to assess the neuroanatomical differences between crack-cocaine patients and paired healthy controls. Fifteen crack-cocaine patients rec...

Differences between co-users of cocaine and crack among Canadian illicit opioid users

Differences in impulsivity and sexual risk behavior among inner-city crack/cocaine users and heroin users.

The current study utilized a sample of 123 inner-city drug users in residential treatment, comparing sexual risk behavior (SRB) across primary users of (a) heroin and not crack/cocaine, (b) crack/cocaine and not heroin, and (c) both heroin and crack/cocaine. Additional analyses also examined impulsivity as a mediator of drug choice and SRB. Results indicated that SRB was higher in primary crack...

Nucleolar Organizer Regions of Oral Epithelial Cells in Crack Cocaine Users

Background: The health risks of crack cocaine smoking on the oral mucosa has not been widely researched and documented. Objective: The purpose of this study was to analyze the proliferative activity of oral epithelial cells exposed to crack cocaine smoke using silver nucleolar organizer region (AgNOR) staining. Methods: Oral smears were collected from clinically normal-appearing buccal mucosa b...
