A pharmacist who bought S4 medications out of a car boot at a Sydney casino to sell to the public has been found guilty of professional misconduct.

The pharmacist, from St Mary’s in western Sydney, came to the attention of authorities in early 2016 following a complaint to NSW Crime Stoppers that someone was selling medications without a prescription.

On the back of the call, authorities tracked down another Sydney pharmacist who in November that year admitted to selling S4 medications at cost price “rounded up to the nearest $5” to the St Mary’s pharmacist at The Star Sydney casino.

He named the St Mary’s pharmacist as the buyer and claimed he made the deal because he felt sorry for him as he “was losing a lot of money at the baccarat tables and was only working one day a week”, the NSW Civil and Administrative Tribunal heard.
