So you use tincture like an edible? Instead of sublingually, your wife just drinks it?
My wife can't smoke either, due to COPD, which is why I'm so determined to
make a tincture. She doesn't want to eat it, and has a very bad time smoking it
due to coughing. I am not sure if a tinc will work for her, actually. But I have to
try to figure a tincture out, by testing on myself that I think might work for her.
Yes, we use tincture as an 'edible', adding it to tea or sometimes I fill a shot glass halfway with orange juice, put a half dozen drops in, and take it like a shot. The beauty of it is that you get to control the dose each time specifically having as much or little as you are in the mood for, using the eye dropper.
If you make a relatively weak batch and start your wife 'low and slow' and let her build up gently, maybe she can learn to trust edibles. I can't smoke, so I've been doing only edibles for over a dozen years now, both THC and CBD (only about 20% tincture, the rest in other forms). Every once in a while I'll take some sublingually, but my wife can't handle that, drops of 151 rum left under your tongue starts to burn pretty quickly. I can't imagine doing that daily, but maybe you get used to it, I've never tried doing it frequently.
