Medicinal cannabis supplier in SA court

An Adelaide woman charged with drug offences over the supply of medicinal cannabis is set to return to court.

Jenny Hallam has previously vowed to fight the allegations and continue her campaign for wider access to the drug.

She will come before the Adelaide Magistrates Court on Friday where she is due to answer the charges of possessing cannabis and manufacturing a controlled drug.

She's expected to plead not guilty which she says will hopefully "set a precedent for all those that follow".

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 but she was not charged until three months later.
