So after hours of reading and watching videos, I see many Tinctures are made with 150 - 180 proof alcohol. Which i'd think would be very strong I read about a women who used 180 proof and she said it burn her lips and in her mouth briefly. Also even tho people only use a few drops my thoughts are how do you know its the CBD doing its magic and your not just on a light drunk from 180 proof alcohol? Sounds dumb I know but I'm still learning, I just think using this grade of alcohol would be doing more harm to the body then good. I also read you can use olive oil and stuff but that it don't absorb as good. Could you make a tincture with normal 40% vodka?
