Gas Station Drugs: the 'legal highs' sold next to the energy drinks

The new dealer is a gas station

No ID checks beyond the register. No prescription. No dealer. The fastest-growing addiction market in America sits between the energy drinks and the lottery tickets: tianeptine, kratom, phenibut, Delta-8 and kava — sold as 'dietary supplements', 'mood enhancers' and 'hemp products'.

The word 'legal' does the marketing. None of these products passed a safety review. Several are actively warned against by the FDA. And at least one behaves like heroin.

The lineup: what's actually on the shelf

ProductSold asWhat it really isThe catch
Tianeptine (ZaZa, Neptune's Fix)'Dietary supplement'An opioid — gas station heroinFull opioid addiction + withdrawal; FDA links it to coma and death
Kratom'Botanical supplement'Plant opioid (mitragynine)Dependence, seizures, liver damage; contaminated batches
Phenibut'Nootropic'GABA drug — Russian prescription anxiolyticDependence in 2–3 weeks; withdrawal can include psychosis and seizures
Delta-8 / HHC / THC-O'Hemp-derived'Psychoactive cannabinoidsSolvent residues, unknown potency; THC-O is federally Schedule I
Kava'Relaxation tea'Liver-toxic sedativeBanned or restricted in several countries for liver injury
The tianeptine warning

The FDA has specifically warned about tianeptine (sold as ZaZa, Tiana, Neptune's Fix) after reports of addiction, overdoses, and death — including a 2024 New Jersey cluster where Neptune's Fix was contaminated with synthetic cannabinoids. It produces opioid-type withdrawal: cold sweats, muscle cramps, insomnia, diarrhea. If someone who uses it heavily stops suddenly, they can become violently ill — like heroin withdrawal, next to a highway.

Why 'legal' is the whole scam

  1. 1. The supplement loophole. Anything sold as a 'supplement' skips FDA approval. The burden is on the FDA to prove harm AFTER people get hurt.
  2. 2. The hemp loophole. The 2018 Farm Act legalized hemp, and chemists responded by converting CBD into Delta-8, HHC and THC-O — psychoactive drugs that never existed in nature.
  3. 3. State patchwork. Tianeptine is banned in a dozen states and legal next door. The same bottle is 'heroin' in Alabama and 'supplement' in Mississippi.
  4. 4. No testing. No batch purity checks, no dosing standards, no childproofing. Gas station shelves are the least regulated pharmacy on earth.

The overdose picture (it's opioid-shaped)

  • - Tianeptine & kratom overdoses look like opioid overdoses: pinpoint pupils, slow breathing, unresponsiveness. Give naloxone — it works on opioid receptors.
  • - Phenibut overdose: extreme sedation, slow breathing — dangerous with alcohol. Naloxone does NOT reverse it; call emergency services.
  • - Kratom seizures happen even without overdose-level doses.
What parents should actually do

- Know the brand names: ZaZa, Tiana, Neptune's Fix, OPMS, Vivazen — these aren't vitamins.

- The gas station/vape shop habit shift (going daily, money disappearing) is the red flag — not a specific product.

- If someone is dependent on tianeptine or kratom: stopping cold turkey causes real withdrawal. A doctor can taper safely, and it's nothing to be ashamed of — it's an opioid dependence, acquired at a convenience store.

If someone is overdosing right now

  1. 1. Call emergency services — say 'possible opioid overdose'
  2. 2. Give naloxone if you have it (it works on tianeptine and kratom)
  3. 3. Stay — they can re-sedate
  4. 4. Tell responders exactly what was taken — the bottle helps
