There have been liquids going around with spice in, so that may put some people off.

So long as it's good stuff inside, you should be good.

How do you plan to make it? What ingredients are you going to use? Pure PG would be horrible and VG doesn't mix with shatter/distillate. Also PEG400 which is used in waxliquidizer is not great for the old lungs. So I'd be quite interested in how you'd make them both safe and tasty.
