I wouldnt use Nucidol (Diazinon).
Organophosphate-pesticides such as diazinon and dichlorvos (banned in UK) act basically as nerve-gas on human nervous-system. It has effect on female fertility and some effect on the developement of fetus.
Most of them will also accumulate in the food-chain and effect many species fertility and or behaviour. Including humans.
Well absorbed through skin and inhalation. I suppose the severe acute effect would be similar to too much meth, coffeine and PCP. Generally I suppose you're likely to experience twitchyness and mood swings,

bit like from smoking pot but in a evil way..
