I bought a lighter from the gas station the other day. When you light it, the lighter flashes blue and red LEDs and also has a button on the side for a bright blue LED. The side button is pretty much a blue flashlight. Well as I was smoking some black tar, I pushed the button to light up the foil so I could see how much was left to smoke. When the blue light hit the Heroin, it let off a glow-like orange.. I thought it was just low quality H, but I bought some off another person (completely unrelated people and H) and it had the same effect. The blue LED flashlight on my lighter makes the Black Tar Heroin glow orange.. what causes this? Has anyone else seen this effect?
