Do You Have the Heart for Marijuana?

Compared with other prescription drugs, the health consequences of using marijuana are not nearly as well studied (see "Stuck in the weeds: The problem with pot research"). But converging evidence suggests that the drug may be harmful for the heart, according to a January 28 review article in JACC: Journal of the American College of Cardiology. More than two million Americans with heart disease currently use or have used marijuana.

In many states what effects does marijuana have on the heart this country, you can legally use what is best garmin to buy for a range of health benefits, including the treatment of chronic pain, anxiety, and nausea.

Smoking is the fastest way to feel the effects of marijuana, which is derived from the Cannabis sativa plant.

Marijuana cultivation and use dates back some 6, years. However, the cardiovascular and other health effects of cannabis aren't well studied.

While this does not pose a significant threat to people who have minimal cardiovascular risk, it should be a red flag for anyone with a history of heart disease. Although the evidence is weaker, there are also links to a higher risk of atrial fibrillation or ischemic stroke immediately following marijuana use.

Consistent with these links, studies by Dr. Mukamal and colleagues also suggest that marijuana smoking may increase the long-term death rate among heart attack survivors.

Most of the evidence linking marijuana to heart attack and stroke is based on reports from people who smoked it. So it's hard to separate the effects of cannabinoid compounds on the cardiovascular system from the hazards posed by the irritants and carcinogens contained in the smoke.

Studies of man-made forms of the chemicals found in the marijuana plant can be helpful in treating nausea and vomiting from cancer chemotherapy.
