I've encountered a question on the Skeptics.SE site asking about the possible affects of certain materials on the human body. In this case, it was the affects and lethality of cigarette smoke in a sealed room. Those kind of questions are off-topic in Skeptics.SE, so I referred the OP to Biology.SE and added Chemistry.SE with a "perhaps" before, as I'm not sure it's on-topic here.
Are questions about the affects of chemical materials on the human body, or any other plant/animal on topic here, or should they all be referred only to Biology.SE.
Examples can be:
- Why does material X has affect Y when it touches the skin/inhaled/ingested/so on?
- What will happen to animal/plant/human that inhales/ingests/so on material X?
- Is there a chemical that can cause affect Y when consumed?
