...you MIGHT, that's just might, be able to create a dose of cannabis extract concentrated enough that someone could actually die from it.

You'd have FAR better luck with many common fruits and vegetables.

People die of water overdoses. Tylenol overdoses, etc.

And a lot of people who survive it are permanently harmed. It's much more dangerous than marijuana, yet it remains on the shelves for anyone to buy OTC. It's ridiculous.

Off topic a bit - I've always wondered how many of the deaths reported as being caused by prescription painkillers like Vicodin are actually due to acetominophen toxicity rather than overdose of the narcotics.

Doses not much higher than the therapeutic dose cause liver damage and liver failure. If it were discovered today it'd never be approved for OTC sale.

while booze killed thousands and thousands? I guess I know which one I would rather take a chance with.

of deaths possibly attributed to marijuana, but that doesn't mean it's impossible

If you browse the general medical journals now and then, you'll find all kinds of strange cases where the interaction several unexpected conditions made diagnosis very difficult

Regular long term smoking of marijuana could have various untoward effects, the most obvious being lung damage, which will reduce oxygen levels in the blood, forcing the heart to work harder; carbon monoxide from the smoke will also reduce blood oxygen levels, forcing the heart to work still harder. So it's possible some long-term heavy users may develop heart problems from use. Another possibility is developing an allergy to some component of the plant or of its smoke: people sometimes develop allegies to various compounds by exposure, and allergic reactions can affect heart function. There may also be some evidence that regular marijuana use can increase norepinephrin levels -- and that would be expected to raise blood pressure. So it's entirely thinkable that a person who smokes multiple times per day over a period of years is elevating the risk of heart attack -- even if this were difficult to find by epidemiology study, heart attacks being rather common

and after 30+ years of sandblasting(silica) and industrial painting, lots of overspray and fumes my lungs are healthier than ever. My lungs are huge from climbing 3-4 700 feet smoke stacks. I honestly believe that the smoking of cannabis protected my lungs. And after losing 60 pounds and getting my pain under control I now use zero blood pressure meds. I do have a minor palpitation every now and then, but I think that is from past use of Voixx and Celebrex. I keep as much man made medicine OUT of my body, as I possibly can.
