Paraquat is highly lethal to mammals, but when smoked, it converts to a more inert compound. Or so the US government now claims, with them saying that the Paraquat led to little if any harm. You can read about it on Wiki.
The lethality is no joke. Like two spoonfuls is guaranteed fatal, right?
I read the article, and of course anyone could have created (or modified) it - so it is, I suppose, just as suspect as everything else on the Internet. With that having been stated, I read that the people involved in the spraying program were the ones who started stating that consuming cannabis that had been sprayed with paraquat was harmful in the first place.
Assuming that was in fact the case (IDK), it might be true - or it might have been something that was spread by a group of people who were anti-cannabis... in order to discourage people from using cannabis. Ya pays yer money, ya takes yer chances, I guess.
I would like to get a chance to read the 1995 study that was referenced in the Wikipedia article, Pronczuk de Garbino J,
Epidemiology of paraquat poisoning, in: Bismuth C, and Hall AH (eds),
Paraquat Poisoning: Mechanisms, Prevention, Treatment, pp. 37-51, New York: Marcel Dekker, 1995 (which does not appear to have been a "government study," AfaIK, and in which the statement "no lung or other injury in cannabis users has ever been attributed to paraquat contamination" was apparently taken from.
Wikipedia said:
Also a United States Environmental Protection Agency manual states: "... toxic effects caused by this mechanism have been either very rare or nonexistent. Most paraquat that contaminates cannabis is pyrolyzed during smoking to dipyridyl, which is a product of combustion of the leaf material itself (including cannabis) and presents little toxic hazard."
I have learned to be somewhat skeptical of a government agency that is - at the best of times - often hamstrung and powerless, and that is known for having questions about the... safety of a thing - and then allowing the entity that is releasing that thing into the environment to determine whether or not it is safe(!!!). IMHO, that is like going to a used car lot and asking, "That car smoked pretty good when you first started it up - are you sure it's going to be reliable and trouble-free for the next couple of years?" and then assuming that the guy is being truthful when he replies, "It sure will be!" Me, I'd want to have a third-party make that determination. One who, you know... doesn't have an interest in selling the car to me.
I also find myself wondering at the inclusion of the word "most" in that quote. By definition,
most is not ALL - therefore,
some can be assumed to have been inhaled in its unchanged form. After the part I quoted, there is mention of a study by chemical company that found rats that had inhaled paraquat showed development of squamous metaplasia in their respiratory tracts after a couple of weeks. But there is no mention of how much and at what concentration. And I have read of substances that'll kill a rat at a given mg/kg dosage but will not do the same to a mouse. This gives me the impression that one can not
always accurately assume that a substance tested on one animal will give the same results (at the same levels) on a different animal, even if they are from two relatively close species.
I also do not recall off the top of my head whether this is a substance that is cumulative in nature, or whether any non-fatal dosage will pass out of the body in such a way that another normally non-fatal dose might actually prove to be fatal.
In other words, I don't know
what to believe.
For the short run of sinsemilia (which the Mexicans knew how to grow long before we did, hell they even named it)
Named it? Er, doesn't
sin mean "without" in Spanish, and
semilla mean "seed" in the same language? If I see a shovel being used, and say, "Digging tool," have I named the implement? Or just
described it, lol?
OtOH - and IMHO - calling seedless cannabis "without seed" is far better than calling it "weed," "dope" or the like :icon_roll. But IDK the root definition of "marijuana," so maybe they did exactly that and I just don't realize it?
