For the trial, they analyzed the effects of cannabis on 26 elderly patients with an average age of 70 during a three-month period. The participants were asked to consume cannabis either by smoking or orally, after which the researchers took note of the results after engaging in several tests including ECG, 24-hour ambulatory blood pressure monitoring, anthropometric measurements, and blood tests. They found that the biggest improvements they saw were in the 24-hour blood pressure tests after 90 days.
