Cannabis Usage Furthers The Risk Of Delayed Cerebral Ischemia

According to new research, cannabis users are more likely to suffer from Delayed Cerebral Ischemia or DCI among patients with aneurysmal subarachnoid hemorrhage (aSAH).

As per the paper published in Stroke, Joshua S. Catapano, M.D., from St. Joseph's Hospital and Medical Center in Phoenix conducted research with his colleagues on 1104 patients who were treated in the facility during a 12-year period. The researchers screened the patients for cannabis users and for other vasoactive substance users.

The research concluded that vasoactive substances like cocaine, methamphetamine, or tobacco had no relation with the rate of DCI in the patients. However, the patients who had cannabis found during the urine screening had a significantly higher rate of DCI.

Among the patients, 46 were found to be cannabis users and among them, the rate of DCI was 52.2% compared to 35.4% which was the average of the test. The research also showed DCI, poor functional outcome, and mortality rates were 36.2%, 50.2%, and 13.5% among the patients being treated. "When people come in with ruptured aneurysms, and they have a history of cannabis use or are positive on a toxicology screen, it should raise a red flag to the treating team that they are at higher risk of vasospasm and ischemic complication," said Dr. K. Rumalla, one of the coauthors of the study.

Researchers also found that radiographic vasospasm is a more common occurrence for regular cannabis users compared to nonusers.
