Hard to follow the thread so I dunno if this is what you are referring to, but I heard the reason spinosad is on the do-not-use list is because it damages(kills?) bees, I think it's supposed to be harmless for humans?
My comment was directed at someone who said "Curious if manufacture says can be used up to day of harvest o fruits and vegetables why should it be of concern."
I'm not knowledge enough to comment on any pesticide in particular but certain pesticides react to being ignited that produce harmful substances. Certain pesticides, spinsoad for instance, can stick around for a couple months. That's why a product which says use on fruits and veges is OK doesn't necessarily apply to cannabis. Cheers
