Queen’s University vice-dean (clinical) and cardiologist Dr. Chris Simpson told the Canadian Stroke Congress THC may encourage development of blood clots connected to stroke, heart disease, and heart failure. A press release from the Heart and Stroke Foundation announcing Dr. Simpson’s statement also worried about cyclical vomiting, and the potential for edibles to be overconsumed by those who don’t wait long enough to find out if they’re working.
- “The harm seems to greatly exceed any potential benefits,” Simpson said. “There is this huge popular misconception about cannabis, driven by social media and the cannabis industry, that it is a medicine or it is harmless.”
- Simpson, former president of the Canadian Medical Association, claimed smoking a joint raises the risk of heart attack within an hour as much as shovelling snow would.
- Responding to criticisms on Twitter of his comments, Simpson said, “There is a lot of promise for CBD, but THC-rich products (particularly combusted) probably do more harm than good.”
