Medical Cannabis - Harmful or beneficial?

By Online News - Rereātea

Wellington researchers are calling for doctors to be more involved in the debate around cannabis as a medicine.

In a recent article in the New Zealand Medical Journal, Dr Giles Newton-Howes, from the University of Otago, Wellington, and Dr Sam McBride, from the Capital & Coast District Health Board, say that although cannabis has a long history of medicinal use, the current evidence is mixed and relatively weak.

They say that the harms of cannabis however have been well identified, and believe this raises some concern about cannabis as a medication and demonstrates the importance of it undergoing the usual regulatory process for medicines.

Dr Giles Newton-Howes says, “There is evidence around the harms and problems of using cannabis but the evidence of its effectiveness as a medicine is weak.

There has been increased interest in cannabis as a medicine both nationally and internationally. Many countries have accepted cannabis as a medication for a variety of purposes, and this has led for calls for it to be medicalised in New Zealand.”

But Dr Newton-Howes says there are issues with this approach to accessing cannabis, which is why he believes doctors need to be at the forefront of the debate surround medicalised cannabis.

“If they do not engage in this debate, the medical profession will risk having to respond to requests after the fact, as opposed to helping to shape policy now.  All doctors should have an interest in this, from primary care physicians to sub-specialists in neurology, psychiatry and associated fields.

We really need to separate out the use of cannabis for medicinal purposes and recreational purposes.

If clinicians are not engaged in this debate now, we cannot influence the direction the use of cannabis will go in.”

Earlier this year Māori MPs shared their stance on the legalisation of medical cannabis. Watch the Te Kāea story here.
