is it illegal if it works?

Michael and Katelyn Lambert

Passed along in email, this tale from Australia:

The father of a young girl who uses medicinal cannabis to treat her severe form of epilepsy has vowed to continue lobbying for law reform, after being found guilty of charges of possession and cultivation.

Michael Lambert was surrounded by his family, including his five-year old daughter Katelyn, when the magistrate handed down his decision in Gosford Local Court today....
Katelyn suffers a debilitating form of epilepsy known as Dravet Syndrome but her doctors have seen a remarkable improvement in her condition since she started taking imported cannabis oil in 2014.
Mr Lambert admitted to the charges but argued he had no choice but to help treat his daughter, who had already suffered irreparable brain damage because of regular, severe seizures.
