When Max Hill looks you in the eye, he still has the piercing gaze of the drug cop he used to be.

Key points:

  • Veteran David Hill has PTSD and was being treated with benzodiazepines, a minor tranquiliser, at a psychiatric ward

  • When he was discharged he deteriorated further as he withdrew from the medication, but medicinal cannabis helped

  • When the medicinal product was no longer available, his father Max turned to the black market. The pair now want to help others

Now in retirement, he's still hunting cannabis suppliers. But this time, it's as a customer on behalf of his son, David — an army veteran of two tours of Afghanistan who uses it to treat post-traumatic stress disorder (PTSD).

"I'm a bit slow on the uptake, I suppose," Max said.

"It took me 22 years in the police force, and 20 years since, to learn that cannabis is a medicine."

This is no 'Breaking Bad' story. Max is openly and defiantly flouting a law he says has passed its use-by date.

His turning point came when David — who was suffering terribly with PTSD — left a psychiatric ward after being treated with massive doses of benzodiazepines.

David said the medication made some symptoms worse.

"The benzodiazepines were not a positive impact on my life whatsoever," David said.

"They initially took away the pain. But then it caused addiction, then overt destructive behaviour. It caused me to cut off from other people. It almost exacerbated my symptoms."

Alone in his apartment, David was deteriorating fast as he tried to come off his medication.

"He was withdrawing terribly," Max said.

"Totally dishevelled, crying uncontrollably… incapable of managing anything other than lying in bed and looking at his phone."

David himself doesn't have much memory of that time, describing himself as a "medicated zombie".

Cannabis helped ease brutal withdrawal

Benzodiazepines, also known as minor tranquillisers, are most commonly prescribed by doctors to relieve stress and anxiety and to help people sleep.

They can also be used to treat alcohol withdrawal and epilepsy.

The Australian Alcohol and Drug Foundation says there is increasing concern among medical professionals about the risks of benzodiazepines, particularly when used for a long time. Withdrawal can be brutal.

And so it was for David Hill.

A month after discharge from hospital, Max brought his son back to the family home to care for him.

David had also been prescribed medicinal cannabis to ease his withdrawal.

At first, it seemed to have little effect.

"I think we came very, very close to losing him," Max said.

"For six long weeks I gave him every meal, every drink, every medication."

Then — quite suddenly — David's condition rapidly improved.

"He's woken up one day, and we're talking like a light switch. He was back to, as I put it, 93 per cent human again. At his depths, he was about 10 per cent human — if that," Max said.

What happened next convinced Max it was cannabis making the difference.

The product they'd been prescribed was no longer available, and the substitute — a much weaker version — wasn't having anything like the same effect.

He'd also seen research from the US and Israel about how cannabis had been used to treat PTSD there.

Turning to the black market

But then, there was the cost — nearly $800 a week.

David pleaded with the Department of Veterans Affairs to help pay for it, but got nowhere.

That's when Max — the former drug cop who used to bust bikies selling dope — decided it was time to go to the black market himself.

"I was beyond caring, frankly," he said.

"What do you do? DVA wouldn't pay for it, despite repeated requests. They wouldn't even give reasons in writing as to why they wouldn't pay for it."

If you or anyone you know needs help:

The Department of Veterans Affairs spends $230 million a year on mental health support for veterans.

It has not closed the door on medicinal cannabis, but says right now there is only "limited evidence" supporting the use of the drug for mental health conditions including PTSD.

"DVA funds treatment where there is a clear evidence base," a spokeswoman said.
