The thc lines are always faint,they never look as bold as the control line. If you have a faint line you will pass the EMIT test. The best thing you can eat is high fiber foods even Metamucil will help. It keeps things flowing so the thc isn't reabsorbed in your bowels. I'm not really sure on the fatty food issue. You really don't want more fat,its where the thc is absorbed. Unless its because its like dillution,the more fat you eat the more the thc is distibuted and therefor dilluted. FBR is the expert on this,maybe he'll be able to answer it.
