Bronchospasms are a possible side effect of some drugs: pilocarpine , beta blockers (used to treat hypertension), a paradoxical result of using LABA drugs (to treat COPD ), and other drugs.
Adopted by Gen Z and Gen Alpha, it gained new prominence in 2024, according to Oxford, as a term used to capture concerns about the impact of consuming excessive amounts of "low-quality online ...
