it's all preference

i know a couple of VETERAN smokers who only smoke greens (the first hit or 2 of the bowl)

i personally just smoke bowls to myself, usually i pack them full, if it is some CHRONIC then i will pack myself a popper (one hit) bowl and enjoy the taste of the greens but its definitely a personal choice

theres nothing wrong with smoking the burned buds, until its white theres still smokeable material in there
