Dude, are you a fool? Concaine, the perfect drug, riiiiight.

There are so many bad side effects, it's hard to believe you didn't come across them as you say you've been researching it. Damage to the brain, heart, nasal passage (if snorted), veins (if injected), and if you smoke it as crack, excess lung and brain damage. Cocaine induced psychosis. Paranoia. Panic attacks. Increased risk of heart attacks and heart failure. Damage to the liver. Seizures. Use can bring out a whole host of predisposed psychological illnesses. Disrupts the sleep pattern.

And all for a 15 minute high? Shit, if I'm going to be risking all that, the high better fucking last at least 12 hours, lol.
