Addiction & Needles

I can understand why anything that requires a syringe could become addicting.
The process one undergoes while sucking a certain amount of a certain substance is a very enjoyable experience.
In my particular situation, I am ejecting Banana Flavored anti Diareha medication into Schnarf's anus...
Kidding, it goes into the corner of his mouth.
I don't think it would matter what flavor it was if it was going into his asshole.
