is not sure himself exactly whats going on.
From what ive gathered there are blood vessels in your nose, similar to those in your mouth and gums. The cocaine
is snorted and "coats" these blood vessels. Your blood is primarily water based, and as soluable coke
is to water it makes it quite easy for the cocaine to pass over into ur blood stream.
The blood that absorbed the coke in ur nose must then make 1 compleate pass around ur body, before making it back to your heart, once it goes through you heart the next stop is the brain.
So to clear anything up, The coke coats the blood vessels in your nose where it is easily absorbed, that blood is then carried around ur body one compleate time before it makes its way back to the heart and to your brian.
