Same concept as a chaser for liquor, only a tracer is made to chase mushrooms, cough syrup and shit like that. You drink some soda to ease the stomach and help prevent nausea, and you see trails of the soda cup becoming 7, 20, 150 soda cups as you attempt to set it back on the coaster on your table.
Psychonut-Pour me a tracer round, sun drop I don't think I can do it at this point man help a brother out I can't see straight.
Sober guy- I'm glad I'm sober, if I was drunk I might shot you because you said something about pouring tracer rounds. Yea I guess so man, you know that shit can't be too good for your brain if you can't pour your own drink and you're drooling all over yourself .

Ok. This one is a trip: Tracers are seen as a result of the vision contorting drug that is LSD. I have never seen tracers on Mushies, Yak, Speed, Green, Ox, Perc, Hydro's, Flex, Trazadone, or Molly. They are Lights/Aura's that emit energy that you transmit from your neurons that have been overloaded by doses. Your Inner Eye Precieves them as a hallucination, but they are real.
Tracers are Life Altering, Take Percaution when Following them, especially if your outside or on a train track when trippin.
