I know everyone here is defending marijuana, and I dont doubt they are using some shit excuses for heart disease but smoking of any kind (cigarettes or weed) has always increased risk of lung cancer and heart attack. I doubt once a month will do it though.

My FIL is pure blood and smokes only weed his whole life. He is 66 He had been battling lung cancer growths the last year and a half. Had surgery last year. They told him to lay off the smoking. He didnt, new growth is back....
