Yup, that's my preferred method of intake. Quick, easy, clean. I don't understand why people bother making lines, or using spoons or whatnot. Sure, the onset is a bit slower, but I'm rarely in that kind of a hurry.

Insufflation generally makes a compound more bioavailable and gives a higher peak but a far shorter duration. It can take 100mg orally to get a normal bump effect. So people view it as wasting coke, but the effects can last 4-6 hours.
Also one of Thomas Edison's favorite drinks! He's famous for rarely sleeping and working continuously -- I wonder how much of the effects are due to Vin Mariani vs his natural work ethic.
