One possible explanation of the commonly reported associations between early onset cannabis use and elevated risks of other illicit drug use is that early onset cannabis use increases access and availability to other drugs. It was this argument that in part motivated policy changes in the Netherlands that led to the de facto legalization of cannabis there. This study examines, using a co-twin control design, whether previously observed associations between early onset cannabis use and elevated… 
An Australian Twin Study of Cannabis and Other Illicit Drug Use and Misuse, and Other Psychopathology
TLDR
Early age of onset of cannabis use was strongly associated with increased rates of subsequent use of other illicit drugs and with illicit drug abuse/dependence; further analyses indicating that some component of this association may have been mediated by increasing exposure to and opportunity to use other illicitdrugs.
Predictors of onset of cannabis and other drug use in male young adults: results from a longitudinal study
TLDR
Consideration of the predictor variables identified within this study may help to identify young male adults for whom preventive measures for cannabis or other drug use are most appropriate, and provide evidence for both the gateway hypothesis and the common liability to addiction model.
Cannabis Involvement and Nonsuicidal Self-Injury: A Discordant Twin Approach.
TLDR
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.
Early cannabis use and DSM-IV nicotine dependence: a twin study.
TLDR
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.
A prospective study of the substance use and mental health outcomes of young adult former and current cannabis users
TLDR
Clear associations exist between cannabis use status in young adulthood and subsequent mental health and substance use and experimentation with cannabis use in the years leading into young adulthood may not necessarily determine an immutable pathway to mental health problems and illicit substance use.
Profiles of drug users in Switzerland and effects of early-onset intensive use of alcohol, tobacco and cannabis on other illicit drug use.
TLDR
Very early onset (at 12 years or younger) intensive use of any substance was a marker for later use of the second group of drugs.

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?
TLDR
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.
Early onset cannabis use and psychosocial adjustment in young adults.
The relationships between early onset (prior to 16 years) cannabis use and later psychosocial adjustment was examined in a birth cohort of New Zealand children studied to age 18 years. Early onset
Patterns of drug use from adolescence to young adulthood: III. Predictors of progression.
TLDR
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.
Stages of progression in drug involvement from adolescence to adulthood: further evidence for the gateway theory.
TLDR
Age of onset and frequency of use at a lower stage of drug use are strong predictors of further progression, and progression to illicit drugs among men is dependent upon prior use of alcohol.
Stepping through the drug use sequence: longitudinal scalogram analysis of initiation and regular use.
TLDR
Analysis of pattern of drug involvement among 4,145 West Coast adolescents over the 4-year span from Grades 7-10 found no evidence that cocaine has become a gateway drug, but provided some support for treating cocaine initiation as a separate stage that precedes the onset of hard drugs other than pills.
Reassessing the marijuana gateway effect.
TLDR
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.

TLDR
Results illustrate a tendency for reported AOs to increase over time, at least for alcohol and illicit drugs, and age at which onset was assessed did not moderate the association between AO and substance-related outcomes.
The dynamics of alcohol and marijuana initiation: patterns and predictors of first use in adolescence.
TLDR
The risk of initiation spans the entire course of adolescent development and young people exposed to others who use substances are at higher risk for early initiation, and proactive parents can help delay initiation.
