Skein

Skein is a fine grayish-blue dust named for the effect it had when eaten: users could supposedly see the weave of time. Skein is a dried and ground fungus, an effective and popular drug. It is mostly seen on the outskirts where it was not so heavily controlled and where there wasn't a huge jail sentence if caught with it.

Effects
Around ten minutes after ingestion, this substance begins to make its effects known. As nausea creeps in, one's vision begins to cloud over on the edges as one begins to see faint snow-like dust out to a range of 10 feet. In this area, the colors of the world become colorless, of black, white, and gray tones. Opening up the user's perception into the Ethereal Plane, this dangerous substance has the potential side effect of stunning the user for an hour, if the user's mind is unable to resist the potential ill effects. Straining the user's body over its duration, the substance can cause them to become woozy, and can potentially cause them to black out if unable to hold their composure.
