I'm completely serious, my undergrad degree is in chem and my grad degree is pharmacology. Bleach effectively "burns up" most organic chemicals. Bleach is so reactive that, while it's "dangerous", it's not a persistent environmental toxin. The thing about ventilation is re:reactions with amines (most drugs have nitrogen's) that make tear gas-like stuff. Whomever disposes of antibiotics is doing this, or chucking it in an incinerator. Burning it is better, but e.g. an oil drum filled with garbage and some gasoline will vaporize a fair bit of stuff and complete combustion is not nearly convenient as stuff you can buy at the grocery store
