The number of children in grades 7 to 12 using opioids in Ottawa roughly doubled from 2021 to 2023, according to recent data from Ottawa Public Health (OPH) and the Centre for Mental Health and Addiction.
整个安省的情况也差不多,从2021的13%,涨到了2023的22%。 7到12年级啊,5个孩子就有1个吸毒

It mirrors an Ontario-wide trend, with the percentage for that group jumping from 13 to 22 per cent over the same period.
