Depressants (non-opioid)
Benzodiazepines, Z-drugs, barbiturates, GHB/GBL, and muscle relaxants — substances that suppress CNS activity.

Prescribed Into a Corner: The Benzodiazepine Dependence Millions Don't Know They Have
Chronic benzodiazepine dependence affects millions prescribed the drugs appropriately. New February 2026 guidelines recommend 5-10% tapers every 2-4 weeks — far slower than typical clinical practice. But the people most affected are already years into protracted withdrawal syndrome, disbelieved by their doctors, managing their own detox with community guidance.
Prescribed and Trapped: Medicare's Benzodiazepine Numbers Reveal a Crisis Built by Doctors
A 2026 Frontiers in Medicine study found Medicare benzodiazepine prescribing rose 51% from 2017–2023 — even as overall U.S. prescribing fell 26%. Seniors average 108 days of medication per year against a 30-day guideline.
Substance Spotlight: Benzodiazepines — The Overlooked Crisis, and a First Glimpse of a Pharmacological Solution
A Translational Psychiatry study identifies TPA023B as the first credible pharmacological candidate for benzodiazepine use disorder — blocking benzo self-administration in primates without precipitating withdrawal, using receptor selectivity that sidesteps the addiction-driving alpha-1 subunit.
Through eight lenses
Science
GABA-A positive allosteric modulators (benzos, Z-drugs), GHB at GHB receptor + GABA-B.
Biology
Sedation, anterograde amnesia, paradoxical disinhibition. Withdrawal: kindling effect, protracted symptoms, seizure risk.
Psychology
Chronic benzo dependence via therapeutic use; iatrogenic pathway; cognitive effects.
Policy
Schedule IV (benzos, Z-drugs), II (barbiturates), I (GHB), but designer benzos (etizolam, flubromazolam) circulate as novel psychoactives.
Trends
Benzo Rx rising; designer benzo detection in overdose deaths; fentanyl-benzo co-use lethal combination.
Treatment
Slow taper (Ashton Manual), CBT for anxiety, flumazenil only for overdose.
Harm Reduction
NEVER mix with opioids/alcohol, test-strip availability for designer benzos, naloxone doesn't reverse benzo respiratory depression.
