Yellowish eyelids, finger nails, toe nails usually mean you are lacking something in your diet. If you are a heavy crack user, I am assuming your diet has changed dramatically. I would def see a doctor or call a medical hotline to find out if it could be something extremely serouis.
Hope this helps!
I cannot think of a reason for yellow eyelids. Yellow conjunctiva suggest liver disease and jaundice; collections of yellow crystals on the corners of the eyelids can be a sign of cholesterol and lipid problems; the only other thing I can think of would be anemia-- that can take away the pinkish color to skin and make the skin look more pale, and maybe that is adding to the yellowish hue.
Regardless of dietary deficiency, active crack addicts have a short life expectancy, and often develop chronic and permanent hallucinations and other forms of mental illness. I recommend that you spend every bit of motivation you have left and work toward getting away from the crack.
