Marijuana Use Dangerous for Older People: Study
Marijuana use dangerous for older people: study Smoking marijuana can be particularly dangerous for older people and in rare cases can trigger heart attacks, according to a study in the latest edition of the journal Circulation, published by the American Heart Association. The study of 3,882 cardiac patients with a median age of 44 found the risk of heart attacks was 4.8 times higher in the first hour after smoking marijuana and 1.7 times higher in the second hour. While only 3.2 per cent of the patients studied reported having smoked marijuana in the previous year, the study's authors noted that marijuana use in the age group prone to coronary artery disease is higher than it was in the past. Previous studies have shown that marijuana smoking causes increased heart rate and blood pressure. "As with any risk factor for heart attack, or for heart disease in general, the risks become more pertinent as we grow older. Marijuana use is no exception," said the study's principal author, Murray Mittleman of Beth Israel Deaconess Medical Center in Boston, Massachusetts.
