I guess I go with what I know. I have not tried to make infused sugar. I'm diabetic, but sugar is sugar whether it's honey or the white stuff. I'm usually not trying to sweeten things, just infuse them with THC. I mix sunflower lecithin into my decarbed concentrate before combining it in the honey as it is supposed to increase the "bioavailability" of the concentrate, and help "emulsify", or combine the oil and water, but there probably is a way to do it with infused sugar. I haven't been able to combine 95% alcohol with lecithin, so although I have high THC available through tincture, it doesn't have the bioavailability of infused honey.
