Leaves going brown?

[M+C]

Hey.
I've been getting this in my piled leaves?
It smells really sweet. Almost like a pipe/cigar? Is it useable or trash? It smells good lol.

I have a lot of leaves looking like that and I plan on smoking them.. Looks good to me.

I found air cured ostrolist, upper leaves all turned out that color. They were potent.
