Why the calculator is silent on this
Widmark does not know about benzodiazepines, opioids, cannabis, antihistamines or diabetes medication. Combined impairment can be severe at a BAC that looks “low.”
Ask a pharmacist
If a label says not to drink, that instruction beats a website. This is not an interaction checker.
Emergency
Unresponsiveness, slow breathing, or suspected overdose is emergency care, not a calculator refresh.
