Marijuana may up heart attack, stroke risk
Marijuana may up heart attack, stroke risk: study | Health | Reuters
WASHINGTON (Reuters) - Heavy marijuana use can boost blood levels of a particular protein, perhaps raising a person’s risk of a heart attack or stroke, U.S. government researchers said on Tuesday.Levels of a protein called apolipoprotein C-III were found to be 30 percent higher in the marijuana users compared to the others. This protein is involved in the body’s metabolism of triglycerides — a type of fat found in the blood — and higher levels cause increased levels of triglycerides.
High levels of triglycerides can contribute to hardening of the arteries or thickening of the artery walls, raising the risk of stroke, heart attack and heart disease.
The study did not look at whether the heavy marijuana users actually had heart disease.
The marijuana users in the study averaged smoking 78 to 350 marijuana cigarettes per week, based on self-reported drug history, the researchers said.
The researchers said the active ingredient in marijuana, known as THC, seems to overstimulate marijuana receptors in the liver, leading to overproduction of the protein. [They] said higher levels of the protein in marijuana users could raise future risk for cardiac abnormalities, blood flow problems, heart attack and stroke.
A U.S. group supporting legal sales and regulation of marijuana disputed the findings. Marijuana Policy Project spokesman Bruce Mirken said, for example, the study involved people who were extremely heavy users.
“I think the low end was 78 joints a week. That’s 10 or 11 joints a day,” Mirken said in a telephone interview.
“We’re talking about people who are stoned all the time. We’re talking about the marijuana equivalent of the guy in the alley clutching a bottle of cheap wine. If you do anything to that level of excess, it might well have some untoward effects, whether it’s marijuana or wine or broccoli,” Mirken added.
“Even if you take this finding at face value, it’s not at all clear that it has any relevance to the real world because there is still no data showing higher rates of mortality among marijuana smokers. If this was a significant cause of cardiovascular disease, where are the bodies?”
Mirken’s right. 78 to 350 joints a week? That’s 11 to 50 joints per day. Let’s see, the government-rolled joints weigh in at about ¾ gram each (you do know there are official US Federal Government joints, right?), but the folks I know roll them a bit bigger (even to the ridiculous cubit-sized 70-gram models). However, most researchers seem happy with the ¾ gram model, so let’s do the math:
Low-end = 11 joints/day = 11 x 0.75g = 8.25g/day = about 2 ounces / week
High-end = 50 joints/day = 50 x 0.75g = 37.5g/day = over 9 ounces / week
So if you are consuming daily enough cannabis to equal about one-half to two-and-one-half pounds per month, then you might run an increased risk of stroke, heart attack, and heart disease. Personally, I’m thinking that at $300 per ounce, you’re more likely to run the risk of bankruptcy!
Yet still, note that the study doesn’t check to see if the heavy marijuana users actually do have heart disease. The research done on the health effects of even heavy marijuana smokers show little if any difference between cannabis users and their non-using counterparts, and some studies even show a benefit from cannabis in treating hypertension.
However, overeating, drinking alcohol, and smoking tobacco are proven to have deleterious effects on the heart and on health. I doubt we’re going to see any major effort to arrest the users of those substances, though.

to be honest the increased risk is actually due to eating unhealthy foods during spurts of the munchies. you smoke all day and odds are you will be eating high on the hog.

This is totally bunk. I have heart disease and have had two heart surgeries. The only reason I stopped smoking is because my job now does random drug screenings otherwise even my doctor told me it is okay for heart patients. The main reason it is good for heart disease patients is because it lowers blood pressure. Cigarettes and alcohol are more dangerous for people with heart disease than marijuana which they are legal. It is also which I was informed by my cardiologist the same as medications to keep me living (isodil and lopressor) which open my arteries and lower my blood pressure.
I wish our government would stop lying and allow us to live in peace. The only problem marijuana has caused me was after being busted, is getting work because I am now a felon.

Marijuana is illegal and will always remain illegal for one important reason. Drug lords stand to lose billions of dollars off of black market sales, and are more than willing to buy senators to keep the market cornered on all illicit drugs.
This goes back to the start of the war on drugs in the 70s (no way! nixon wasn’t corrupt! /sarcasm) and perhaps all the way back to 1937, as after the end of the alcohol prohibition (i believe it was ‘33) “speak easys” could no longer charge upwards of 400% on inferior alcohol because it was legal.
This is also in my opinion why only smaller dealers(competition) seem to be incarcerated without remorse, while the kingpins remain untouched.
So next time you hear a politician say its okay for aids and cancer patients to suffer for a “noble cause”, or contradicting valid evidence that Pot is harmless, keep in mind hes probably being pummeled with drug money to say so.
*I do not support the use of any addictive or harmful drug, including alcohol. Marijuana, however, fits into neither of these categories. I do, however, believe that this is the land of the free, and prohibition of ANYTHING other than violence goes against the very idea of our great nation.
