A woman suffering from fibromyalgia is believed to be the first patient in the UK to be prescribed medical cannabis following a change in the law.
Carly Barton has been suffering from the chronic pain condition since suffering a stroke in her early twenties.
The former university lecturer began using cannabis illegally around two years ago.
Last month, she was prescribed medicinal cannabis by Greater Manchester-based private pain specialist Dr David McDowell in what they believe is a UK first.
The three-month prescription will cost her around £2,500.
Doctors have been able to prescribe cannabis products to patients in the UK since November 1 after the drug was rescheduled.
But Ms Barton, who lives in Brighton, says interim guidelines, which make it difficult for NHS doctors to prescribe the drug, are “prohibition under a different name”.
“The guidelines they have produced aren’t working. In the month that they have been produced, no doctor has felt guided to write a prescription,” she said.
“Those guidelines need setting on fire as far as I’m concerned, and the NHS specialists need to be made to feel comfortable about making a clinical decision.”
