You take a big drink of the Taco Pop and hold it in your mouth. The fizz and the gasses of the drink flow up into your sinus and it penetrates the mucous membranes. This gives you a pleasant rush. You love to do this. On the street its called a nose high. it only works for the first sip but its a wow. You feel a strong fleeting pleasure. You finish the drink and the caffeine flows into your bloodstream lighting it up with chemical smiles.
