Chronic cannabis users in danger of losing their minds

(Talk about an alarming headline. I didn't make it up), the story is available here
Cape Times Chronic cannabis users in danger of losing their minds February 8, 2005
Washington: Marijuana users have faster blood flow in their brains, even after a month of not smoking, US researchers have reported.
The findings suggest they have narrowed arteries, similar to patients with high blood pressure and dementia, and could help explain reports that heavy marijuana users have trouble with memory tests, say researchers Ronald Herning and Jean Lud Cadet at the National Institute on Drug Abuse in Baltimore.
They tested 54 marijuana users, who smoked anywhere between two and 350 joints a week, and 18 non-smokers.
They used Doppler sonograms to measure blood flow in volunteers' brains at the beginning of the study and after a month in which everyone abstained.
The smokers had faster blood flow at the start and after a month of abstinence, Herning and Cadet reported in the journal Neurology.
The smokers also had a higher pulsatility index score, or PI, a measure of resistance to blood flow. The researchers believe the higher PI is caused by narrower blood vessels.
"The marijuana users had PI values that were somewhat higher than those of people with chronic high blood pressure and diabetes," Herning said.
"However, their values were lower than those of people with dementia. This suggests that marijuana use leads to abnormalities in the small blood vessels in the brain."
The researchers found that blood flow improved in people who smoked up to 70 marijuana cigarettes a week - people they defined as moderate users - after a month of avoiding cannabis. Heavy users, who smoked up to 350 joints a week, saw no change in blood flow even after a month.
Researchers at Montreal's McGill University have reported that chronic consumers of cannabis lose molecules called CB1 receptors in the brain's arteries. This reduces blood flow to the brain, causing attention deficits, memory loss, and impaired learning ability. - Reuters

They ran this story on CNN last night. It smells like propaganda to me!

#1) Study group was 72 people. This is a small group!
#2) 350 joints a week is the same as a 2 and 1/2 pack a day cigarette smoker.
#3) I find it funny that the first place this story ran was the "Cape Times" in Capetown South Africa.
#4) I find it interesting that there is no press release about this at the National Institute on Drug Abuse. Which is where the story clams to be from.
#5) The National Institute on Drug Abuse is a government agency which raises red flags in my book.
#6) It seems to be a well timed article, With the largest state in the lower 48 (Texas) considering a medical marijuana bill.

The devil weed clearly has those users already hooked at 350 joints a week.
When will they just let it go?

I think its propaganda, but even if it true, the pot heads blood pressure didnt go down because they were still fucking smoking it most likely. I mean what are they going to do drug test them when they knew they were smoking already? If i was in that study i would have kept smoking, theres no way they could tell. Peace

i just went to the doctor the other day, and for the first time in my life i had high blood pressure. and since in the past month or so ive been smoking way more i attributed to the smoking. (and lack of excercise) so there might be some truth to this.

well smoking anything increases blood pressure but if your the average healthy person otherwise its not a problem.

Very difficult, it not impossible, to pull anything meaningful out of such a small, and scewed sample.

They didn't isolate the Cannabis as being the problem, IMO. Eating, Vaporizing, and Smoking Cannabis need to be examined individually. I'd venture to say that the smoking its self affected this study.

inhaling smoke causes veins to get smaller. This is why people who smoke cigarettes get headaches. I'm pretty sure thats been known for quite some time. This article seems real bogus to me.

"Shocking that smoking 350 joints a week is not healthy. Beware: 140 cups of coffee in one hour will deliver a lethal dose of caffeine. Eating 10 raw potatoes may kill you. How can such a study on pot be used to justify cannabis prohibition? Thanks for the chuckle"
I couldn't have said it better myself:
