Appreciate the link. Respectfully, I see a lot of jumping to conclusions and not much science as it relates to cannabis. No doubt that too much Neem or azadirachtin is a bad thing but Iím having trouble seeing the minute amount absorbed into a bud having much effect and, when it does, itís on those with particular sensitivities or compromised systems. I can certainly see a niche market for neem-free cannabis for those who suffer those issues but to condemn Neem on the whole for something that might
cause a rare issue in some people, at a statistically insignificant level, seems extreme. As one article referenced pointed out, cannabis had been grown and used in Asia for thousands of years with no hint at this issue. What the article conveniently leaves out is that those same cultures regularly used Neem in their agriculture. So, drawing a connection between cannabis grown with Neem products and folks suffering from CHS seems pretty hazy to me. Thereís a LOT of supposition and theory here without any direct science that I can see.
There is an awful lot of cannabis being grown with the use of Neem, from oil to cake, thatís being injested by millions and millions of people without any negative effects. If CHS was a widespread issue and there was some conclusive scientific evidence that said it was caused solely and specifically by azadirachtin, Iíd be more concerned. So far, though, thatís not the case. But hey, itís a free world and every grower has to make their own choices. Itís a good thing to know that people have these concerns; so they can make their own informed decisions about how they grow and what products they use. For now, Iím going to remain pro-neem as itís better than chemical pesticides, imo. Iíve never heard of anyone having CHS except on the internet. I suspect that one of these days California will add Neem to the endless list of things that have to a warning label, like water. Lol. Drinking too much water can kill you. Lol.
In this case the OP was asking about Neem composting. I wonder if composted Neem even has azadirachtin in it after the microbes and maybe the worms get ahold of it?
