Timothy Oldham was a strong student and a champion tennis player.

This link between the medication and mental health has already been discovered in the US, where the drug (known as Chantix) has carried a ‘black box warning’ about side effects since 2009, after pharmaceutical company Pfizer settled a class action taken against them by 3,000 plaintiffs.
But the Australian version carries no such warning.
