Yes ~ they do have a very big drugs problem in Iran ~ so many hung for that reason!!
They recently arrested a American-Armenian Christian women and said she had spy equipment in her teeth.
(Reuters) - An Iranian-Dutch woman, arrested after taking part in anti-government protests in Iran in 2009, has been hanged for drug smuggling, the semi-official Mehr news agency said on Saturday.
"A woman smuggler named Zahra Bahrami, daughter of Ali, has been hanged today for the possession and selling of narcotics," Mehr reported, quoting the court.
The 45-year-old woman's daughter was quoted by the rights group International Campaign for Human Rights in Iran as saying the drug charges were fabricated after Bahrami was arrested for taking part in protests in December 2009.
Mehr reported that she had been found guilty of smuggling cocaine into Iran from the Netherlands and was found with 450 grams of the drug in her possession. Iran does not recognise dual citizenship.
