chloroform

[WS]

Hi Allen,

don't worry. But if you think you feel unwell, see a doctor.

Not so long ago, it even was used in medicine as narcotic. Organic
chemists routinely use it as a convenient solvent and probably breath
a lot of it and sometimes even pour it over their hands. Chronic
exposure will harm your liver however.

Have fun,
