BACKGROUND
In the Czech Republic in 2010 a law was introduced decriminalizing personal possession of small quantities of several illicit drugs, including cannabis.
METHODS
We use 2012 survey data to examine the effect of a change in cannabis policy on the age of onset of cannabis use. We estimate the effect of the policy change using a mixed proportional hazards framework that models the transition to first cannabis use.
RESULTS
The change in cannabis policy did not affect the transition to first cannabis use.
CONCLUSION
We find no evidence of cannabis decriminalization affecting the age of onset of cannabis use.
背景
2010 年，捷克共和国出台法律，将个人持有少量几种非法药物（包括大麻）非刑罪化。
方法
我们使用 2012 年的调查数据，研究大麻政策的改变对大麻使用起始年龄的影响。我们使用混合比例风险框架来估计政策变化的影响，该框架对首次使用大麻的转变进行建模。
结果
大麻政策的改变并未影响首次使用大麻的转变。
结论
我们没有发现大麻非刑罪化会影响大麻使用起始年龄的证据。
