The human brain is hardwired to respond to reward or pleasure, and if it weren’t so, no one would eat or have sex.

But that same “pleasure circuit” is also the underpinning of addiction, explained researcher and psychiatrist Nora Volkow, head of the National Institute on Drug Abuse (NIDA) at the National Institutes of Healt, and world leader in the neurobiology of diseases of reward and self-control.

In Canada, prescription painkillers and illicit fentanyl are together fuelling a national epidemic of opioid-related overdoses, killing more than 2,800 people last year.

Volkow will be speaking in Montreal on Thursday at the Low-Beer Memorial Lecture on mental illness and addiction, hosted by AMI-Quebec, a group founded 40 years ago to help families manage the effects of mental illness through support, education, guidance, and advocacy.
