在萨斯喀彻温省的王子港冲马桶，污水讲述的毒品故事与哈利法克斯或温哥华截然不同。
Flush a toilet in Prince Albert, Sask., and the wastewater tells a very different drug story than it does in Halifax or Vancouver.
加拿大统计局的新数据显示，在八个加拿大城市的污水中检测到的毒品存在显著差异：冰毒和可卡因的含量在王子港最高，在萨斯卡通和新不伦瑞克省的蒙克顿也处于较高水平。哈利法克斯的冰毒含量最低，但可卡因含量相对较高。芬太尼在大温哥华地区的含量仍远高于其他地区。
New Statistics Canada data shows striking differences in drugs detected in wastewater across eight Canadian cities: Methamphetamine and cocaine levels were highest in Prince Albert and also elevated in Saskatoon and Moncton, N.B. Halifax had the lowest methamphetamine levels but comparatively high cocaine levels. Fentanyl remained dramatically higher in Metro Vancouver than elsewhere.
加拿大统计局的调查测量的是污水样本中的毒品代谢产物——即人体分解毒品后排出的化学副产物。样本采集窗口为每两个月为期一周。
The StatCan survey measures drug metabolites — chemical byproducts excreted after the body breaks down drugs — in wastewater samples collected during one-week sampling windows every two months.
数据涵盖2024年1月至2026年3月，覆盖服务约920万人口的汇水区。加拿大统计局警告，这些数据并不能准确显示有多少人使用毒品或消费量多少。
The data, from January 2024 to March 2026, covers catchments serving about 9.2 million people. StatCan cautions that it doesn't show exactly how many people use a drug or how much they consume.
但加拿大统计局分析师Sianne Kuang告诉CBC新闻，这“是该污水处理厂服务区域内毒品消费的一个相当好的替代指标”。
But it is a "pretty good proxy of drug consumption" within the area served by a treatment plant, StatCan analyst Sianne Kuang told CBC News.
王子港的冰毒含量在所有受监测城市中最高，且冰毒和可卡因的波动幅度也最大。
Prince Albert Prince Albert had the highest methamphetamine levels of any city monitored and the greatest fluctuations in both methamphetamine and cocaine.
2026年3月，其估算的冰毒负荷量为每千人每天2003毫克——是多伦多约214毫克的九倍多。
In March 2026, its estimated methamphetamine load was 2,003 milligrams per 1,000 people per day — more than nine times Toronto's roughly 214 milligrams.
西门菲沙大学公共政策学院教授Kora DeBeck表示：“导致不同物质使用的因素有很多，其中之一就是市场上有什么可供购买。”
"There's many different drivers of different substance use, and one of them is just what is available in the market," said Kora DeBeck, a professor in the School of Public Policy at Simon Fraser University.
萨斯卡通也记录到了一些最高的冰毒含量，与蒙克顿并列，仅次于王子港。其2026年3月的读数约为每千人每天958毫克。
also recorded some of the highest methamphetamine levels, along with Moncton, but behind Prince Albert. Its March 2026 reading was about 958 milligrams per 1,000 people per day.
DeBeck表示，地区性模式可能与毒品如何进入当地市场有关。
DeBeck said regional patterns may be connected to how drugs reach local markets.
这似乎与贩毒以及毒品生产和贩运网络的运作方式联系更为紧密，而我们对此实在缺乏深入了解。的甲基苯丙胺负荷于2025年1月达到每千人每天约1,071毫克，2026年3月为624毫克——几乎是多伦多当月水平的三倍。也记录到了一些最高的甲基苯丙胺水平。
"It seems much more connected to drug trafficking and how the networks of drug production and trafficking work, and we really don't have good insight into that." 's methamphetamine load reached about 1,071 milligrams per 1,000 people per day in January 2025 and stood at 624 in March 2026 — nearly three times Toronto's level that month. also recorded some of the highest methamphetamine levels.
加拿大统计局指出，2024年新不伦瑞克省63%的兴奋剂毒性死亡涉及甲基苯丙胺——这是大西洋省份中涉及甲基苯丙胺比例最高的。
Methamphetamine was involved in 63 per cent of stimulant toxicity deaths in New Brunswick in 2024 — the highest share involving methamphetamine among Atlantic provinces, StatCan noted.
蒙克顿于2025年3月加入调查，提供的数据较少，难以据此识别趋势。
Moncton joined the survey in March 2025, providing less data from which to identify trends.
哈利法克斯 2026年3月，其记录的甲基苯丙胺为每千人每天仅56毫克，在受监测城市中最低，而可卡因约为1,734毫克。阿尔伯特亲王市的可卡因读数约为5,296毫克——大致是哈利法克斯的三倍。
Halifax In March 2026, it recorded just 56 milligrams of methamphetamine per 1,000 people per day, the lowest among the cities monitored, while cocaine was about 1,734 milligrams. Prince Albert's cocaine reading was about 5,296 milligrams — roughly three times Halifax's.
2024年新斯科舍省86%的兴奋剂相关死亡涉及可卡因，而涉及甲基苯丙胺的为14%。加广早前的报道也记录了可卡因在该省药物相关死亡中日益增长的作用。
Cocaine was involved in 86 per cent of stimulant-related deaths in Nova Scotia in 2024, compared with 14 per cent involving methamphetamine. Earlier CBC reporting also documented cocaine's growing role in drug-related deaths in the province.
阿尔伯塔大学成瘾医学医生兼研究员蒙蒂·戈什表示，利用不同前体、配方和混合物进行的本地生产，可能形成独特的区域供应。
Monty Ghosh, an addiction physician and researcher at the University of Alberta, said local production, using different precursors, formulas and mixtures, can create distinct regional supplies.
“他们使用的配方并不相同。他们不一定使用相同的化合物或药物。”大温哥华地区 大温哥华地区在所有八个城市中持续记录到最高的芬太尼水平。
"They don't have the same formula they're using. They don't use necessarily the same compounds or drugs." Metro Vancouver Metro Vancouver consistently recorded the highest fentanyl levels of all eight cities.
与2024年相比，2025年和2026年初的平均水平有所下降，加拿大统计局称这一变化与温哥华非法药物死亡率下降同时发生。德贝克警告，不应单纯将芬太尼的流行视为对需求的回应。
Average levels declined in 2025 and early 2026 compared with 2024, a change StatCan says coincided with a drop in Vancouver's unregulated drug death rate. DeBeck cautioned against viewing fentanyl's prevalence simply as a response to demand.
“最初人们并没有要求或想要芬太尼。它只是出现了，就在那里，随后人们对其产生了依赖，”她说。
"People didn't demand or want fentanyl in the beginning. It just arrived and was there, and then people became dependent on it," she said.
Ghosh表示，芬太尼测量值的下降并不一定能反映阿片类药物供应中的所有情况，他指出：“市面上存在不同形式的芬太尼，而这些可能未被此处测量到。”该市的甲基苯丙胺水平远低于Prince Albert和Saskatoon的记录值，但另一种兴奋剂却脱颖而出。
Ghosh said falling fentanyl measurements don't necessarily capture everything happening in the opioid supply, noting that "there's different forms of fentanyl out there, which may not be measured here." 's methamphetamine levels were far below those recorded in Prince Albert and Saskatoon, but another stimulant stood out.
从2024年7月到2026年3月的可用报告月份来看，多伦多在八个城市中平均MDMA水平最高，约为每千人每天40毫克。
Across available reporting months from July 2024 to March 2026, Toronto had the highest average MDMA levels of the eight cities, at about 40 milligrams per 1,000 people per day.
该市在研究中测量的多种阿片类药物水平相对较低，这一点尤为突出。
stood out for comparatively low levels of several opioids measured in the study.
其可待因水平在参与城市中最低，从未超过每千人每天约44毫克，而所有城市的平均水平范围约为97至219毫克。
Its codeine levels were the lowest among the participating cities, never exceeding about 44 milligrams per 1,000 people per day, compared with a combined-city average ranging from about 97 to 219.
蒙特利尔也记录到了最低的美沙酮水平，以及一些最低的羟考酮和吗啡读数。
Montreal also recorded the lowest methadone levels and some of the lowest oxycodone and morphine readings.
其兴奋剂概况更接近多伦多，甲基苯丙胺相对较低，而MDMA读数相对较高。Ghosh表示，废水有助于揭示模式，但不应孤立地解读。“它只是全貌的一个部分。”
Its stimulant profile was closer to Toronto's, with relatively low methamphetamine and comparatively higher MDMA readings. Wastewater can help illuminate patterns, Ghosh said, but it shouldn't be read in isolation. "It's only one part of the picture."
StatCan警告称，通勤、旅游以及特殊事件导致的临时人口变化都可能给估算带来不确定性。
Commuting, tourism and temporary population changes caused by special events can introduce uncertainty into the estimates, StatCan cautions.
