Yeah:

Where's your sense of adventure?

I made an educated guess that my lungs wouldn't melt and my brain wouldn't shut off. It worked, was nice, might try it again.

There are essential oils I would dare do this with, but in terms of bronchial irritation and LD50, lavender oil is pretty tame.

Super real.

Lavender has a wonderful sedating effect. I like to science, so I vaped some essential oil once upon a time.. very nice calming effects that make you want to sleep, but that doesn't knock you out. Great sleep, nice and cozy.

There's limited hard science becasue what's the incentive??

But thousands of years of use in practice, so that says something.
