An Adelaide woman has pleaded not guilty to drug offences over the supply of medicinal cannabis and says she hopes a jury will acquit her on grounds of "medical necessity".
Speaking outside of the Adelaide Magistrates Court after entering her plea on Thursday, Jenny Hallam said she felt she had a responsibility to circulate the drug.
"I will not let people die when I have a responsibility to keep them alive," she said.
"I'm hoping, having a jury trial, that I'm not going to be able to find people that are callous enough to think that what I did was the wrong thing," she said.
"I'm hoping that the jury will find me not guilty on the grounds of medical necessity."
Flanked by supporters, Hallam said she had provided the Director of Public Prosecutions with about 200 letters demanding the charges be dropped.
She said the only victim of the crime was pharmaceutical companies.
"Nobody was hurt, nobody was injured," Hallam said.
"Nothing has happened other than the pharmaceutical companies have shown that their drugs don't work."
Access to medicinal cannabis has been legal in South Australia for some time but it can only be prescribed by doctors under certain circumstances.
Proponents say, for some people, getting hold of suitable products remains difficult.
Hallam's home at Hillier, in Adelaide's north, was raided by police in January 2017, but she was not charged with drug offences until three months later.
She has pleaded not guilty to both manufacturing and possessing a controlled drug and will appear in the District Court for arraignment on March 2.
