Cannabis is often marketed today as natural, harmless, even therapeutic — available legally from corner stores, dispensaries, and websites with minimal regulation or oversight. But at Centrum Pharmacy, we want to make one thing clear: cannabis is a potent drug, and like all drugs, it comes with real risks — especially when used without medical supervision.
Cannabis isn’t just a casual substance — it interacts with your body, your brain, and your long-term health. And while cannabis may hold therapeutic potential for some, its misuse, particularly among young people and vulnerable populations, can have serious consequences.
What You Need to Know
The popularity of cannabis has surged, and with it, so has its casual use for everything from stress and anxiety to sleep and pain. But just because it’s legal doesn’t make it safe for everyone.
- Cannabis can cause or worsen psychiatric conditions, including depression, anxiety, and in some cases, psychosis — a condition where individuals lose touch with reality.
- Young people are especially at risk, particularly those with a family history of mental illness or who use cannabis frequently or in high-potency forms.
- Cannabis today is much stronger than in decades past, with high concentrations of THC — the psychoactive compound that can trigger mental health issues.
The Dopamine Link: What New Research Is Telling Us
Recent studies published in JAMA Psychiatry and other peer-reviewed journals have revealed a deeper understanding of how cannabis may lead to psychosis — a severe mental health condition.
Researchers using a specialized type of brain imaging (neuromelanin-MRI) found that people with Cannabis Use Disorder (CUD) had increased dopamine activity in areas of the brain also linked to schizophrenia. The more severe their cannabis use, the stronger this signal became.
This research shows:
- A biological basis for why cannabis can cause psychotic symptoms.
- A dose-dependent response: the more someone uses, the higher their risk.
- People with CUD often don’t perceive the harm cannabis is doing to them — even when measurable brain changes are occurring.
In people already diagnosed with psychotic illnesses like schizophrenia, cannabis can lead to relapse, worsening symptoms, and treatment failure.
