Don't worry be happy that wine you had with your kind organic veggie lasagna probably had more imid in it...no really it is rather non toxic to humans and I'm sure you waited 30 days so smoke up it's definitly less harmfull than the air in socal.
I ran the citrus and veggie at 10ml per gallon in my drip system for 8hrs and saw no ill effects as a bonus it has little or no N and is ph neutral.... I'll be treating them all again the day I flip em just to be sure.

Definitely more than 30 days, I never use the imid in bloom.
