To determine the comparative levels of violent offending and victimization among regular methamphetamine and heroin users.
Cross-sectional Setting Sydney, Australia.
A total of 400 regular methamphetamine (METH) and heroin (HER) users (118 methamphetamine users: METH; 161 regular heroin users: HER; 121 regular users of both: BOTH).
Eighty-two per cent reported a life-time history of committing violent crime, 41% in the past 12 months. There were no group differences in life-time violence, but the METH group were significantly more likely than the HER group to have committed violence in the past 12 months (odds ratio 1.94). Nearly all (95%) reported that they had been a victim of violent crime, 46% in the preceding 12 months, with no group differences. Those who had committed a violent crime in the past 12 months were 13.23 times more likely to have been a victim in that period. The majority believed it unlikely that they would be a victim of (78%), or commit (87%), a violent crime in the next 12 months.
Regular methamphetamine use appears to be associated with an increased risk of violent offending, but not victimization, compared with heroin use.
确定经常使用甲基苯丙胺和海洛因的人群中暴力犯罪和受害的相对水平。
横断面研究设置在澳大利亚悉尼。
共有 400 名经常使用甲基苯丙胺（METH）和海洛因（HER）的人（118 名甲基苯丙胺使用者：METH；161 名经常使用海洛因的人：HER；121 名同时经常使用两种药物的人：BOTH）。
82%的人报告有一生的暴力犯罪史，其中 41%发生在过去 12 个月内。在一生中的暴力行为方面，各组之间没有差异，但 METH 组在过去 12 个月内发生暴力行为的可能性明显高于 HER 组（优势比 1.94）。几乎所有人（95%）报告说他们曾是暴力犯罪的受害者，其中 46%发生在过去 12 个月内，各组之间没有差异。在过去 12 个月内实施过暴力犯罪的人在该期间成为受害者的可能性是 13.23 倍。大多数人认为他们在未来 12 个月内不太可能成为（78%）或实施（87%）暴力犯罪的受害者。
与使用海洛因相比，经常使用甲基苯丙胺似乎与暴力犯罪的风险增加有关，但与受害无关。
