Nope, it is a bag with a knot tied in the top. Trust me I know one when I see one, and that is what it is 100%.
Just eyeballing it like I said looks like about a quarter chunk, or maybe 5 or 6 grams.
And unfortunately I can confirm from experience that after doing coke all night and being completely at the end of your rope, you want to jump into the shower/bath just to relax and calm you the fuck down because you are so spent.
