chem
Beakers and formulas
Chem is informal shorthand for chemistry, especially as a school subject: I have chem at two o'clock, chem lab.
It also appears in compounds: chem teacher, biochem.
In gaming and online contexts, chem can refer to chemical substances or drugs, particularly performance-enhancing ones.
