Substance involvement in these cases

Across all cases, Alcohol is the substance most linked with domestic violence — it appears in 14% of these cases, 2.8× the rate in cases that do not mention domestic violence. Within the substantiated slice the multiplier shrinks or flips, because a substantiated domestic violence case does not need a co-occurring risk factor to justify substantiation.

Every substance class shown against domestic violence, ranked by all-cases lift. Both slices appear so the substantiation artifact is visible, not hidden.
