The Centre for Addiction and Mental Health is focusing its no one left behind fundraising campaign on substance use and addiction.  Opioid use and deaths are still the biggest crisis with more 7,300 deaths in Canada in 2022. But use of stimulants like meth amphetamine, also known as crystal meth, is also increasing.

Dr. Leslie Buckley is Chief of Addiction Services at CAMH and she says mixed drug toxicity, for example meth and an opioid is a major contributor to overdoses and deaths.
