New Study Raises Health Concerns Over Marijuana

Posted: Updated:
Young and middle–aged adults who use marijuana could be putting themselves at risk for heart–related complications, even death.

That's according to a new study published in the journal of the American Heart Association.

French researchers looked at about  2–thousand health complications  involving marijuana. 

35 were cardiovascular–related, including 20 heart attacks and 9 deaths.

"We used to think marijuana was a very safe drug,” says Cardiologist Robert Kloner. “But as more and more marijuana is being used there have been more identifiable cases of cardiovascular complications. It can increase heart rate and this can increase the demand for oxygen by the heart."

He believes the number of cardiovascular complications from marijuana is even higher.

"There's probably an under-reporting that's occurring, so not everyone that has a cardiac event that uses marijuana is going to report that."

26–year–old Dave weaver smokes marijuana regularly and says the new findings won't keep him from lighting up.

"It's like drinking a beer at the end of the day, just helps you calm down, relax, and take the stress off,” he says.

As more states legalize marijuana for recreational and medical use, some experts are calling for a national system to track health complications related to marijuana.
