Introduction. Cannabis use is strongly associated with the use and abuse/dependence of other illicit drugs. Gateway and common liabilities models have been employed to explain this relationship. We sought to examine this association using a combination of the discordant twin design and modeling methods. Method. We assess the relationship between early cannabis use and the subsequent use and abuse/dependence of other illicit drugs in a population-based sample of male and female twin pairs using… 

Adolescent alcohol use is a risk factor for adult alcohol and drug dependence: evidence from a twin design

Early regular drinking is associated with later alcohol dependence and use, abuse/dependence on drugs, and unique environmental factors contribute to transitions from early regular alcohol drinking to use, use and dependence on alcohol and other substances.

Early cannabis use and DSM-IV nicotine dependence: a twin study.

Early-onset cannabis users are at increased risk for nicotine dependence, but this risk is attributable largely to common genetic vulnerability, while there is no evidence for a causal relationship between cannabis use and nicotine dependence.

Contrasting models of genetic co-morbidity for cannabis and other illicit drugs in adult Australian twins

Model-fitting results suggest that common genetic, shared and unique environmental factors are responsible for the association between cannabis experimentation, early use, repeated use and A/D problems and OID experimentation or problems.

Tobacco, cannabis, and other illicit drug use among Finnish adolescent twins: causal relationship or correlated liabilities?

The findings suggest that several common genetic influences may be related to tobacco use and illicit drugs but that a search for specific genes underlying illicit drug use is justifi ed as well.

Associations of alcohol, nicotine, cannabis, and drug use/dependence with educational attainment: evidence from cotwin-control analyses.

Even in a veteran population with access to military educational benefits, early alcohol use, alcohol dependence, and daily nicotine use remained significantly associated with years of education after controlling for shared familial contributions to educational attainment.

Associations of age at cannabis first use and later substance abuse with mental health and depression in young men

Findings show that early cannabis onset is associated with later impairments in mental health and depression; however, these are largely explained by later substance abuse.

Cannabis Involvement and Nonsuicidal Self-Injury: A Discordant Twin Approach.

Results suggest that NSSI is associated with cannabis involvement via differing mechanisms and, for lifetime cannabis use, the lack of association in discordant pairs suggests the role of shared genes and family environment.

Genetic and environmental influences on cannabis use initiation and problematic use: a meta-analysis of twin studies.

Vulnerability to both cannabis use initiation and problematic use was influenced significantly by A, C and E, and there was a trend for a greater C and lesser A component for Cannabis use initiation compared to problematic use for females.



Escalation of drug use in early-onset cannabis users vs co-twin controls.

CONTEXT Previous studies have reported that early initiation of cannabis (marijuana) use is a significant risk factor for other drug use and drug-related problems. OBJECTIVE To examine whether the

Does cannabis use encourage other forms of illicit drug use?

The view that cannabis may act as a gateway drug that encourages other forms of illicit drug use is supported, and the possibility remains that the association is non-causal and reflects factors that were not adequately controlled in the analysis.

Specificity of genetic and environmental risk factors for use and abuse/dependence of cannabis, cocaine, hallucinogens, sedatives, stimulants, and opiates in male twins.

In an adult population-based sample of male twins, both the genetic and the shared environmental effects on risk for the use and misuse of six classes of illicit substances were largely or entirely nonspecific in their effect.

Genetic and environmental influences on drug use and abuse/dependence in male and female twins.

Co-occurrence of abuse of different drugs in men: the role of drug-specific and shared vulnerabilities.

Evidence is found for a shared or common vulnerability factor that underlies the abuse of marijuana, sedatives, stimulants, heroin or opiates, and psychedelics that is influenced by genetic, family environmental, and nonfamily environmental factors.

The Harvard Twin Study of Substance Abuse: what we have learned.

It is found that the co-occurrence of illicit drug abuse and major depression is due to unique environmental influences, and the phenotypic association between symptoms of conduct disorder and alcohol and marijuana dependence is due largely to shared environmental influences.

Does marijuana use cause the use of other drugs?

Early marijuana use by itself, even after control for other covariates, increases significantly the use of other illicit drugs, and the common-factor model of Morral et al provides an alternative interpretation.

Patterns of drug use from adolescence to young adulthood: III. Predictors of progression.

Multiple factors are involved in the progression to prescribed drugs, with adolescent depressive symptomatology and use of other illicit drugs important for both sexes, and maternal use of psychoactive drugs, dropping out of school, and prior use of marijuana of additional importance for women.

The shifting importance of alcohol and marijuana as gateway substances among serious drug abusers.

The results suggest that alcohol is not a prerequisite for progression to marijuana, but marijuana use nearly always precedes use of more serious substances such as cocaine, crack and heroin.

Reassessing the marijuana gateway effect.

The results demonstrate that the phenomena used to motivate belief in such an effect are consistent with an alternative simple, plausible common-factor model, which has implications for evaluating marijuana control policies that differ significantly from those supported by the gateway model.
