Hhahaha, tbh no i dont know what cocain smells like, i only know what it looks like from movies. However in regard to the addictiveness yes you are all right.
I find even in the mornings i walk into the lounge and it just smells of her, its total necter.
And yes i am constantly sniffing her head/neck/under neck/under wing pretty much every where decent, she even lifts her wing now to let me, i do it that much.
I repay her by letting her play with my ear. She loves to put my lobe in the back of her beak and almost baby suckle. Weird i know but she likes it and it gives me goosebumps. She preens me i preen her, works well.
