The health risks of crack cocaine smoking in public settings have not been well described. We sought to identify factors associated with public crack smoking, and assess the potential for a supervised inhalation facility to reduce engagement in this behavior, in a setting planning to evaluate a medically supervised crack cocaine smoking facility.
Data for this study were derived from a Canadian prospective cohort of injection drug users. Using multivariate logistic regression we identified factors associated with smoking crack cocaine in public areas. Among public crack smokers we then identified factors associated with willingness to use a supervised inhalation facility.
Among our sample of 623 people who reported crack smoking, 61% reported recently using in public locations. In multivariate analysis, factors independently associated with public crack smoking included: daily crack cocaine smoking; daily heroin injection; having encounters with police; and engaging in drug dealing. In sub analysis, 71% of public crack smokers reported willingness to use a supervised inhalation facility. Factors independently associated with willingness include: female gender, engaging in risky pipe sharing; and having encounters with police.
We found a high prevalence of public crack smoking locally, and this behavior was independently associated with encounters with police. However, a majority of public crack smokers reported being willing to use a supervised inhalation facility, and individuals who had recent encounters with police were more likely to report willingness. These findings suggest that supervised inhalation facilities offer potential to reduce street-disorder and reduce encounters with police.
在公共场所吸食 crack 可卡因的健康风险尚未得到充分描述。我们旨在确定与在公共场所吸食 crack 可卡因相关的因素，并评估在计划评估医疗监督 crack 可卡因吸食设施的环境中，监督吸入设施减少这种行为的潜力。
本研究的数据来自加拿大前瞻性注射吸毒者队列。我们使用多变量逻辑回归确定与在公共场所吸食 crack 可卡因相关的因素。在公开吸食 crack 可卡因的人群中，我们确定了与使用监督吸入设施意愿相关的因素。
在报告吸食 crack 可卡因的 623 人样本中，61%的人报告最近在公共场所使用。在多变量分析中，与公开吸食 crack 可卡因独立相关的因素包括：每日吸食 crack 可卡因；每日注射海洛因；与警察接触；以及从事毒品交易。在亚分析中，71%的公开吸食 crack 可卡因者表示愿意使用监督吸入设施。与愿意使用相关的因素包括：女性性别、从事危险的烟斗共享；以及与警察接触。
我们发现当地公开吸食 crack 可卡因的现象普遍存在，这种行为与与警察接触独立相关。然而，大多数公开吸食 crack 可卡因的人表示愿意使用监督吸入设施，而最近与警察接触的人更有可能表示愿意。这些发现表明，监督吸入设施有潜力减少街头混乱和减少与警察的接触。
