N.S. company launching clinical trial to examine magic mushrooms as treatment for PTSD

About an hour outside Halifax, tucked away behind the HantsCommunity Hospital in Windsor, N.S., workers in a small facility are growing their own magic mushrooms and synthesizing what makes them magic: psilocybin.

Its operators, Halucenex Life Sciences Inc., arealsoin the midst of the province's first clinical trial using the psychoactive substance psilocybin something researchers hopewill demonstrate the safeness and efficacy of using it totreatpost-traumatic stress disorder.

"We're really excited about seeing the data that comes out of this and the effects it's going to have on PTSD, I really think it could give people the big reset that they need to move forward in life," said David James, chief science officer for Halucenex,which is funding and conducting the trial.

James says 1,500 people have applied from all over the world to be part of this study, which shows the huge demand for effective psychologicaltreatments. Only 20 were chosen for the study and the company plans to shareits results with Health Canada.

"We're hoping that the data that we receive from this critical clinical trial is efficacious enough to show all Canada that it does work, it's safe, and hopefully, move the sector forward to help more people."

Recent studies have identified the therapeutic benefits of psychedelics such as psilocybin, LSD and MDMA, also known as ecstasy,to treat PTSD, depressionand addiction.

Individuals with PTSD often show increased reactivity in the amygdala, a part of the brain connected to memory and emotions. That activitymay make it harder toprocess traumatic memories.

Some research has shownthat psilocybin, the psychedelic compound found in magic mushrooms, can reduce activity in the amygdala when people respond to threats. This means patients withPTSDcouldreduceanxiety and inappropriate responsesby taking it.

Other health-care practitioners say more research is needed.

Health Canada notes research is continuing, but there are no approvedtherapeutic psilocybinproducts and alsowarns of risks.

"For individuals predisposed to or with existing psychiatric conditions, there may be an elevated risk of side effects. This association is still being evaluated," it says on its website.

The trial, which began earlier this month and is scheduled to wrap March 2023, involves administering a synthesized version of psilocybin to 20 patients. The group is made up of doctors, therapists, veterans and first responders, all diagnosed with PTSD.

The trial permits participants to take psilocybin, which is considered an illegal substance under the Controlled Drugs and Substances Act, in a safe and supervised setting.

Patients will initially take a 10-milligram dose, known as a microdose. They'llcome back a week later and take a macrodose of 25 milligrams.

Typically, a macro dose, often called a "hero dose" by those in the psychedelic community, means consuming five grams of mushrooms or more, and feeling the effects for five to eight hours. These effects includeseeing, hearing or feeling things that are not there. Some may also experience anxiety, fear, nausea and muscle twitches accompanied by increased heart rate and blood pressure.

"[Twenty-five milligrams], that's enough to kind of do what we're hoping to do, which is a kind of a whole mental reset for PTSD,"said James, who also has a PhD in chemistry.

Though none of the trial participants were available to speak on the subject, Don Hunter, senior vice-president of business development for the company, says he experiencedpsilocybin treatment this past summer.

After months of research and years of trying other PTSD treatments, Hunter made the choicetoconsume psilocybin tea at a facility in Costa Rica.

The hallucinogenicaffectmade himfeel like he was literally digging through his trauma and blocked thoughts.

"I was chipping through a wall, but still didn't know where I was going," said Hunter when describing what it felt like to be on a psilocybin"trip."

Eventually after hours of "digging," he said he felt as though he had emergedon the other side of the wall and was able to stand face to facewith thoughts he had purposely repressed.

"I don't want to say this is a silver bullet because I do believe there is a need to further your treatment.The big thing is, besides ... really changing my mindset and being reactionary it also allowed me to have a different mindset when it came to listening to others and being more compassionate with others."

Nurse Brenda Perkswill help guide trial participants through their psychedelic experience. Shesaysbad experiences are often dependent on the environment and what form of psilocybinis taken.

"Recreational trips that are unguided and unsupported, you don't know what you're taking, you don't know what strain you're taking. Different strains have different strengths. In this setting, we eliminate the fears of the bad trips, so to speak, because you're guided, it's all in a controlled setting," said Perks, who has been a nurse in varying medical settings for 35 years.

Psilocybe cubensis is the most common type of magic mushroom, but there are nearly 100 different strains.

She saidthis trial will beNova Scotia's formal introduction to the therapeutic effects of psychedelics. She hopes such research will eventuallylead to theirlegalization.

"By doing the trials, we're hoping to remove the fears and anxieties around so-called psychedelic drugsthat's what we're hoping to gain is more support around that so that we can remove some old ways of thinking around psychedelics."
