A woman using medicinal cannabis to fight chronic pain says she will "openly break the law" after running out of money for private recipes.
Carly Barton, who feels "frustrated" and "imprisoned in a very unusual situation," says he has illegally approached for breeding and buying drugs.
She can not get it on the NHS because it is classified as an unguarded drug, she says.
Twenty-two-year-old uses medicinal cannabis because it has fibromyalgia – conditions that cause pain throughout the body – after a stroke in the early twenties.
It is believed that the former university lecturer, who taught fine arts, became the first person prescribed by cannabis in the UK in December, after being legally approved for medical use in November.
But private receipts cost about 1300 pounds a month, and its savings were cleared.
Previously it was prescribed a strong opioid, including morphine and fentanyl, but left her feeling "zombed" and still "crying with pain."
"I'll open the law violation until I get access to the drug or give me some exemption," she said.
"I do not see myself as a criminal. There are two doctors who have prescribed it to me, and there is now an unclear law that does not see it as a potential drug."
"It seems you can not legally get cannabis in the NHS because the evidence still does not exist (let's say it's safe) because it was so illegal for so long."
In an open letter to Katy Bourne, Sussex Crime Commissioners, Mrs. Barton says she has "no choice" but to raise a cure to control her pain.
Ms Barton added, "I do not want to be a zombie or a back wheelchair. I want to live my life and cannabis allows me.
"I feel confined to a very unusual situation. I'm frustrated."
The Department of Health and Social Welfare said that the National Institute of Excellence in Health Care and Care was asked to "develop additional clinical guidelines" and "work with England for Health Education to provide additional training".
The spokesman said: "The government has fulfilled its promise, and doctors specialists can now prescribe cannabis-based medical products where clinical evidence of benefits exists.
"We also promote more research through the National Institute for Health Research to further improve the evidence base."
