Claudia H has become the first German to be allowed legal access to cannabis to treat the multiple sclerosis (MS) she has been suffering from for 14 years.
Strict conditions apply to the permit, which came into effect in late August, and the treatment has to be conducted under the supervision of a doctor.
Despite the widespread evidence that cannabis can help MS patients, as well as cancer and HIV/AIDS sufferers, counter their pain and assist in curbing weight-loss, German doctors are not allowed to prescribe it.
A synthetic alternative is available in the form of Dronabinol, the active ingredient in cannabis, but the state health insurance will not pay the costs, and 60 capsules can cost up to $2,000.
Many patients resort to illegal sources for the drug, enduring the hassle of negotiating the drug-dealers' milieu and running the risk of brushes with the law.
Police and the courts in Germany tend to take a relaxed view on the possession of small quantities of cannabis, but practice varies from state to state.
Claudia H was one of those prepared to run the risks, even though at the age of 51, this ran counter to her nature.
"I tried out all the legal medications, but the side effects were unacceptable," the software technician told the Sueddeutsche newspaper.
She has been unable to walk for the past 10 years, and her condition began to deteriorate markedly five years ago.
