Myclobutanil, when combusted, Turns to hydrogen cianide.
but if you burn anything wont it give off HC?
theres a real long eagle 20 thread on here and like you said jury still out. if a un sprayed joint gives of eg 20ng of hc, what does a sprayed joint give off 22ng or 2000?
Mycobutanil is not approved for tobacco for a reason it isn't safe to consume when combusted, my opinion is if they cannot have on tobacco it shouldn't be on anything that is combusted, there is a lot of added things to tobacco so I think that says a lot, even if it is extracted you would need to run a pesticide screen to see what's left in the extract and if it's any I would personally not consume it or provide it to others, edibles I have a different opinion as it can be used on fruit and veg that is consumed and it can be broken down in the body but even then I wouldn't want to consume or allow someone else to do so.
There's simply not enough evidence to make a definitive conclusion.
A reasonable assumption is vaping/smoking cannabis laced with pesticides couldn't be good for anyone ......... but the fact is people have been smoking exactly that for 50 years now ...... so you'd expect if it truly was as bad as the fear mongers are portrying it .... there would be case after case of affected people .... but there's none.
Draw your own conclusions ............
