Psychedelic drugs like psilocybin, LSD, and MDMA are revolutionizing mental health treatment by promoting neuroplasticity and enabling new nerve connections. They show promise in treating depression, PTSD, and addiction, with effects lasting weeks. However, experts urge caution due to potential risks like lingering hallucinations or misuse. Rigorous research and regulation are crucial for safely unlocking their therapeutic potential.
Psilocybin’s Role in Neuroplasticity and Healing: In a quiet renaissance that’s reshaping the future of mental health treatment, psychedelic drugs like psilocybin, LSD, and MDMA are emerging as powerful tools to combat some of the most stubborn psychological conditions. What was once relegated to countercultural experiments is now fueling cutting-edge research, offering new hope to millions suffering from depression, PTSD, and addiction.
A growing body of evidence suggests that these substances might hold the key to improving mental health by promoting neuroplasticity—the brain’s ability to form new nerve connections. This could explain the long-lasting therapeutic effects of psychedelics.

“This is why psilocybin may help so many individuals overcome the effects of long-term mental health issues—by reversing nerve changes,” says Dr. Peter Silverstone, a psychopharmacology expert at the University of Alberta. “It has the potential to be the most dramatic treatment breakthrough in mental health for decades.”
Silverstone is at the forefront of this movement. Inspired by the transformative potential of psychedelics, he founded Zylorion Health, an Edmonton-based company, in 2021. The company is part of a broader wave of renewed interest in these compounds, which began to regain scientific attention in the early 2000s after decades of legal and cultural suppression.
Historically, psychedelics have deep roots. Indigenous peoples in South and Central America have used magic mushrooms in spiritual and healing rituals for centuries. These ancient practices underscore what modern science is now beginning to validate: psychedelics can profoundly alter consciousness and promote mental healing.
The Western fascination with psychedelics dates back to the 1930s when Swiss chemist Albert Hoffman accidentally synthesized LSD. His first “bad trip” famously evolved into a day-after epiphany: “The world was as if newly created.” LSD became a focal point of brain science in the 1950s, but its association with the counterculture movement of the 1960s led to its ban in 1970.
Psychedelic research went underground for decades, resurfacing with a groundbreaking 2006 study in Psychopharmacology that demonstrated psilocybin could trigger mystical-type experiences with significant, sustained psychological benefits. Since then, the field has grown rapidly, spurred by high-profile endorsements, including Michael Pollan’s bestseller How to Change Your Mind and Silverstone’s book, The Promise of Psychedelics.
Canada has played an outsized role in the modern history of psychedelics. In the 1950s, British researcher Humphry Osmond conducted pioneering studies at the Saskatchewan Mental Hospital, coining the term “psychedelic” and collaborating with luminaries like Aldous Huxley. Today, Alberta leads the charge.
In 2022, Alberta became the first Canadian jurisdiction to regulate the use of psychedelics in therapy, paving the way for clinical trials. Earlier this year, Alberta Blue Cross broke new ground by including psychedelic-assisted therapies in its insurance coverage—a move that could inspire similar policies nationwide.
The renewed interest in psychedelics isn’t just about their ability to induce mystical experiences. Recent studies point to their remarkable biological effects, particularly their role in enhancing neuroplasticity. Psilocin, the active metabolite of psilocybin, binds to brain receptors that foster the growth of new neurons and synapses.
“These findings are extraordinarily fascinating,” Silverstone says. “They provide a scientific explanation for the profound effects of psychedelics on mental health.”
High doses of psychedelics can produce hallucinatory experiences that leave lasting impressions. Patients often describe gaining profound insights into their lives, which can facilitate healing. However, the real promise may lie in microdosing—taking small, sub-perceptual amounts of psychedelics regularly.
Some studies suggest microdosing can alleviate anxiety, depression, and PTSD without the intense hallucinatory effects of higher doses. A 2018 study found that half of the participants who microdose for a year reported improved mental health compared to conventional treatments.
Despite the excitement, experts urge caution. Psychedelics are not risk-free. Unsupervised use can lead to adverse outcomes, including hallucination persistence, anxiety, and, in rare cases, psychosis.
Silverstone points to examples like a Berlin clinic that treats patients experiencing lingering effects from bad trips. He also highlights more dramatic incidents, such as the Alaska Airlines pilot who attempted to shut down a plane’s engines mid-flight after taking mushrooms.
“These substances are powerful and must be used responsibly,” he says. “The question is, how big is the risk, and how do we manage it?”
The Federal Drug Administration (FDA) recently declined to approve MDMA for therapy, not due to safety concerns but because of flawed study methodologies. This highlights the need for rigorous research to ensure psychedelics deliver on their promise.
After reviewing hundreds of studies, Silverstone ranks psilocybin as the most promising psychedelic for mental health treatments. Its ability to enhance neuroplasticity, combined with a relatively low-risk profile, makes it a standout.
Ketamine, originally developed as an anesthetic, earns Silverstone’s “silver medal.” Under medical supervision, it has shown dramatic success in treating depression. However, its potential for misuse and side effects, including neurological damage, temper its appeal.
MDMA, commonly known as “ecstasy,” takes third place. It has proven effective in treating PTSD but poses risks such as neurotoxicity and heart damage, particularly with chronic use.
The field of psychedelic research is evolving rapidly. “A prediction I made a year ago could already be outdated,” Silverstone says. Yet the pace of discovery is a testament to the transformative potential of these substances.
Health law expert Timothy Caulfield shares Silverstone’s optimism but warns against hype. He emphasizes the need for evidence-based practices and careful regulation to avoid the pitfalls of overpromising.
“Panaceas don’t exist,” Caulfield says. “But psychedelics may get us closer to breakthroughs than we’ve been in decades.”
As the world grapples with a growing mental health crisis, psychedelics offer a glimmer of hope. From ancient rituals to modern medicine, these substances are reemerging as powerful tools to heal the mind.
