Western Province has recorded a sharp increase in mental illness cases over the past two years, with health officials linking the rise to marijuana abuse.
According to Western Province Health and Medical Service – Mental Health Coordinator, Michael Lealognono, Gizo Hospital recorded a total of 400 mentally ill patients between 2024 and 2025.
He said three to four patients visit the hospital daily with most of them being ages between 15 and 35.
“This is a massive increase and we are aware of the root cause. Most of these patients are addicted to marijuana while others are due to chronic diseases and stress disorders,” Lealognono said.
He explained that most patients were born normal but developed illness after prolonged marijuana use.
“A large number of cases come from Vella and Rannonga Islands, raises suspicion that individuals in these areas may be producing and smuggling marijuana,” Maukera said.
He stressed the need for police to intervene and investigate the reports.
The health coordinator further warns that regular marijuana smoking can impair brain development, memory, and learning capacity, particularly among young people whose brains are still developing.
Long-term use is also associated with increased risks of anxiety, depression, and in some cases, psychosis.
Island Sun understands that physically, marijuana use can damage the lungs, cause persistent coughs, and weaken the immune system, making the body more vulnerable to infections.
Beyond health, it can also result in poor academic performance, reduced productivity, and strained family and community relationships.
Cases of accidents and risky behaviours have also been linked to marijuana use due to impaired judgment and slower reaction times.
Health authorities caution that the growing prevalence of marijuana-related mental health cases places additional strain on already limited medical resources.
Stronger awareness programs, prevention strategies, and early interventions are urgently needed to minimize the harm associated with marijuana use.
