| Abstract |
To test whether speed of transition from first use to subsequent use of cannabis is associated with likelihood of later cannabis dependence and other outcomes, and whether transition speed is attributable to genetic or environmental factors. Cross-sectional interview study SETTING: Australia PARTICIPANTS: 2239 twins and siblings who reported using cannabis at least twice (mean age at time of survey = 32.0, 95% CI 31.9 - 32.1, range 22-45). Time between first and subsequent cannabis use (within 1 week; within 3 months; between 3 months - 12 months; more than 1 year later), later use of cannabis and symptoms of DSM-IV cannabis abuse/dependence. Multinomial regression analyses (comparison group: more than 1 year later) adjusted the association between speed of transition and the outcomes of cannabis daily use, abuse/dependence, and treatment-seeking after controlling for socio-demographic, childhood, mental health, peer and licit drug factors. Twin modelling estimated the proportion of variance in transition speed attributable to genetic (A), common environment (C) and unique environmental (E) factors. Subsequent use of cannabis within one week of first use was associated with daily use (OR 2.64, 95% CI 1.75 - 3.99), abuse and/or dependence (OR 3.25, 95%CI 2.31 - 4.56) and treatment-seeking for cannabis problems (OR 1.89, 95%CI 1.03 - 3.46). Subsequent use within 3 months was associated with abuse and/or dependence (OR 1.61, 95%CI 1.18 - 2.19). The majority of the variation of the speed of transition was accounted for by unique environment factors (0.75). Rapid transition from initiation to subsequent use of cannabis is associated with increased likelihood of subsequent daily cannabis use and abuse/dependence. This article is protected by copyright.

Attention Score in Context
This research output has an Altmetric Attention Score of 8. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 July 2015.
All research outputs
#4,384,238
of 24,571,708 outputs
Outputs from Addiction
#2,482
of 6,140 outputs
Outputs of similar age
#52,273
of 271,794 outputs
Outputs of similar age from Addiction
#40
of 82 outputs
Altmetric has tracked 24,571,708 research outputs across all sources so far. Compared to these this one has done well and is in the 82nd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 6,140 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 25.2. This one has gotten more attention than average, scoring higher than 59% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 271,794 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 80% of its contemporaries.
We're also able to compare this research output to 82 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 51% of its contemporaries.
