Helsinki University Hospital (HUS) has treated its first cases of drug-induced cerebrovascular incidents linked to recreational cocaine use. Neurologist Marjaana Tiainen confirmed that a small number of young adults, all under 30, suffered strokes or brain haemorrhages related to the drug.
The patients had no underlying health conditions and their cocaine use occurred in non-chronic, recreational settings. These incidents mark a shift in the patient profile typically seen at HUS, where such cases had until now been limited to amphetamine users.
"In countries with long-standing cocaine use, this is a known phenomenon. We've not previously encountered it here," Tiainen told STT. She noted that Finland is now seeing the same health consequences observed elsewhere.
The neurological damage caused by these strokes is often permanent. While no deaths from cocaine-induced brain haemorrhages have occurred at HUS, some patients are left with lasting symptoms. Recovery focuses on preventing further damage and improving independence through rehabilitation.
"Cocaine sharply raises blood pressure and constricts blood vessels. When a vessel ruptures, blood leaks into brain tissue, causing irreversible damage," Tiainen said. "Even though rehabilitation helps, full recovery is not guaranteed."
In addition to strokes, cocaine is increasingly linked to heart conditions. Cardiologist Mikko Parry from HUS Heart and Lung Centre said several cases of cocaine-related heart attacks are treated each year. Cocaine affects the heart by limiting oxygen supply through intense vasoconstriction, leading to spasms or full blockages in coronary arteries.
Prolonged use may lead to heart failure. Cocaine combined with alcohol, a common practice in Finland, increases health risks further by producing cocaethylene, a toxic metabolic by-product.
According to Ulriika Sundell, medical director at A-Clinic, cocaine has become a mainstream drug in Finland. "It’s used by the middle class, students, professionals. These aren't traditionally seen in drug treatment programmes," she said. Many avoid seeking help due to stigma or fears of legal consequences.
Healthcare professionals insist that no information about drug use is shared with police unless required by law. “We don’t report use to authorities. Our role is to treat patients and improve health outcomes,” Parry said.
In some regulated sectors, such as professional driving or specific healthcare jobs, substance use must be reported. Other mandatory reporting obligations include child welfare concerns and driving safety issues, Sundell noted.
She added that patients often worry about repercussions, but efforts are made to handle legal duties in ways that minimise distress. “If someone voluntarily seeks help, we try to address any mandatory reporting together to reduce anxiety.”
Experts stress that while cocaine use in Finland remains relatively limited, the rise in health complications is notable. The recent cases reflect a global trend reaching Finnish hospitals, prompting concern about the drug’s growing impact on public health.
