How one mother’s tragedy is driving change in nitrous oxide policies

Julia Charleston advocates for legal changes after her son Robert Howland, a U.S. Air Force veteran, died by suicide following an addiction to nitrous oxide, a legal but misused inhalant. Despite its dangers and increasing misuse, nitrous oxide remains largely unregulated, prompting Charleston to form the advocacy group People Against Nitrous Oxide, calling for restrictions or a ban to prevent further tragedies.
