Some General ramblings of a very old stoner
(who is currently stoned)
Lethal Concentration for neem oil inhaled is 6.2mg/l
(LC50 - Median lethal dose)
Now if that is the LC50 level, what kinds of affects and ailments occur prior to death at lower levels ?
I have no clue, but I have been smoking since 1963 and have known a lot of stoners in my life... and I have never seen or more importantly heard of anyone experiencing Cannabinoid hyperemesis syndrome.
I did get to live through the president of the United States (Carter) attempting to poison off all the stoners with Paraquat... but that's another story.
Cannabis is known as one of the most efficient accumulator plants in existence, it is used by governments and corporations world wide to suck up heavy metals, radioactive waste, and toxic waste. It is used to clean up soil at Superfund sites as well as nuclear accident sites.
It is basically nature's vacuum. Which is why before I would buy any growing medium I always checked into any and all testing that was done for heavy metals, contaminants, etc. And it is why I no longer use commercial products on my grows, Neem oil included.
Every little bit helps...
Know this, any info put out there is subject to change in your lifetime whether it be from stoners, or the government, or from peer reviewed papers and research. I don't trust much of any of it, and you may learn not to as well.
I have seen far too much incorrect info published and put out as fact that is no longer an accepted fact.
Asbestos is completely safe for any application, butter is even healthier in larger amounts as it lubricates your arteries, It is impossible for GMO's to ever escape into nature, Mercury is safe as a children's toy, Cigarettes improve lung function, Lead is safe when eaten, oh... and Teflon is safe to eat as well....
Those are just a few of the things that were put out there that have changed I'm my lifetime. There are many many more... plus throw in revisionist history and... well.... if you are paying attention now you won't trust much out there either when you get to be my age.
