A former nurse who grew cannabis to treat her mentally ill son has been spared a prison sentence.
Miriam Anna Down, 75, was charged after she was found with 19 cannabis plants in her Bayswater garden and 1.42 kilograms of marijuana leaf in her home, the West Australian District Court heard on Tuesday.
Down used the cannabis to treat her 42-year-old son George, who has a mental illness.
She was sentenced to 10 months in prison, suspended for 10 months, with the judge noting there was no commercial gain involved in the crime.
Down's tenant, 53-year-old Judith Esme Robinson, was charged with assisting Down and was handed a 10-month intensive supervision order.
