In the present study, the effects of bilateral microinjections of cannabinoid CB1 receptor agonist and antagonist into the basolateral amygdala (intra-BLA) on nicotine-induced place preference were examined in rats. A conditioned place preference (CPP) apparatus was used for the assessment of

OBJECTIVE To compute the common and specific genetic and environmental contributions to nicotine dependence (ND) alcohol dependence (AD) and cannabis dependence (CD). METHODS Twin model. METHODS Data from 1874 monozygotic and 1498 dizygotic twin pair members of the Vietnam Era Twin Registry were

Several lines of evidence have shown that the endogenous cannabinoids are implicated in several neuropsychiatric diseases. Notably, preclinical and human clinical studies have shown a pivotal role of the cannabinoid system in nicotine addiction. The CB1 receptor inverse agonist/antagonist rimonabant

To evaluate the possible pulmonary effects of habitual marijuana smoking with and without tobacco, we administered a detailed respiratory and drug use questionnaire and/or lung function tests to young, habitual, heavy smokers of marijuana alone (n = 144) or with tobacco (n = 135) and control

OBJECTIVE Although a number of studies have examined the respiratory impact of marijuana smoking, such studies have generally used convenience samples of marijuana and tobacco users. The current study examined respiratory effects of marijuana and tobacco use in a nationally representative sample

BACKGROUND Although the "stage theory" suggests that marijuana use occurs after the initiation of tobacco smoking, substantial evidence exists that they often occur concurrently, and that the use of marijuana may influence the use of tobacco. METHODS This study uses trajectory analysis to examine

OBJECTIVE Several reports suggest that cannabis use is associated with an earlier age at onset of psychosis, although not all studies have operationalized cannabis use as occurring prior to onset of symptoms. This study addressed whether pre-onset cannabis use, alcohol use, and tobacco use are

BACKGROUND Cannabis use is more common among tobacco users than nonusers, and co-use (i.e., use of both substances individually) may be increasing. Better understanding of patterns and correlates of co-use is needed. The current study aimed to compare rates and correlates of tobacco and cannabis

Cannabis and tobacco co-use is prevalent, but consensus regarding the reasons for co-use among adults and the degree of interrelatedness between these substances is lacking. Reasons for co-use have been explored with younger users, but little data exists for more experienced users with entrenched

UNASSIGNED There is concern about potentially causal effects of tobacco use on psychosis, but epidemiological studies have been less robust in attempts to minimize effects of confounding than studies of cannabis use have been. UNASSIGNED To examine the association of patterns of cigarette and

Studies have highlighted psychosocial factors associated with drug use among adolescents. Association of specific psychiatric comorbidity with substance use has not been properly established in Brazil. This study aimed to investigate alcohol, tobacco, and marijuana use by 15-18-year-old high school

BACKGROUND Cannabis remains the most widely used illicit substance by adolescents and is typically consumed by this population in the context of ongoing tobacco use. Human studies have shown that both cannabis and tobacco exert effects on cognitive function; however, little is known about possible

Few studies have examined in detail how specific behaviors of close friends put adolescents at risk for specific types of substance use. Using a prospective, longitudinal design, we examined how well the substance use of 248 young urban adolescents was predicted by perceptions of their 3 closest
