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.
A former pope used and endorsed a coca wine back in the day. Seems it was very popular for a while.
Edit: Interesting that someone would downvote something that is purely subjective.
