Going up!
Once the crack has been devided into the desired line lengths, it is then commonly ingested by way of the nasal passage.  This is referred to as snorting. To do this, you will need a straw, or if you will, a rolled up one hundred dollar bill.
Wasted!
Once a sufficient amount of crack has been absorbed into the blood stream, the user will experience a high.  This is when reality becomes greatly distorted, and things are not what they seem to be.  Often, it will be a pleasureable experience, and laughter typically ensues.  Observe as Vomit God "freaks out, man!"
Don't let a bad trip discourage you..whatever doesn't kill you, makes you stronger!
However, even the best high can quickly turn bad.  This is known as a bad trip.
Save some for us, Vomit God!
Upon returning to the painful, icy grip of reality, an overwhelming sense of hunger is often felt.  This is known as getting the munchies.  Watch as Vomit God partakes of some delicious country fried potatoes.  Salt and pepper to taste.
