Hmm... Probable overdose?

It was tagged as drugs on pixiv. Seems like an odd place to OD though.

Maybe it's more of someone just being tired and burdened and so she's lying down just anywhere she can?

It actually pretty heavy handed?

Pills here!

Is it possible it was tagged as drugs simply for being in a drugstore?

An image that actually wouldn't be too badly mangled by the old CGA's default Cyan, Magenta, White, Black color scheme. That's a true rarity.
