Balvinder Banga, for the RPS, said Iraqi born Farahani worked at the Mostyn Street store twice as a locum on August 28 and September 5, 2004.
"Within that short period of time the pharmacist noticed that a number of Codeine Phosphate tablets were missing and informed the security manager, Edward Dodsworth.
"Mr Dodsworth approached Farahani and the two had a conversation in the staff room. "Farahani was informed there had been a discrepancy of Codeine Phosphate and was asked to empty his rucksack.
"A packet of 28 Codeine
Phosphate was discovered and Farahani admitted he had taken them from Superdrug."
The search also uncovered 12 Codeine Phosphate pills, a pack of 14 Zolpidem Tartrate and 14 Kapake capsules - all pain killers.
The police were called and Farahani, who trained in Sweden, admitted taking the drugs, telling officers he used them for "terrible back pain".
Asked about the Kapake pills, Farahani told police a friend gave them to him.
Mr Banga said: "It is the case of the society those facts intrinsically led to a breach of responsibility of key three in the code of ethics and standards."
Farahani, who now runs a beauty therapy business in Lancashire, told the panel: "There is no excuse good
enough. "The only thing was that when this happened I went through a very difficult time in my life."
He said both he and his wife were suffering from depression at the time.
Lord Peter Fraser of Carmyllie QC said Farahani's actions were unacceptable and so serious he could be struck off.
He added: "The committee is troubled by this case and our view is we want a medical report from Mr Farahani's GP.
"We propose to adjourn this case for three months to enable this to be obtained for us."
He said Farahani must also provide a written undertaking he will not work as a pharmacist for the next three months.
