These products are commonly sold in gas stations and vape/smoke shops. They are marketed as “herbal,” “natural,” “energy,” “focus,” or “mood” aids — but may contain potent synthetic stimulants, opioid-acting compounds, or high-dose hemp derivatives. Labels are often incomplete or inaccurate. Use these examples to recognize packaging and start calm, fact-based conversations at home.

Why it’s risky:
• DMHA is not an approved dietary ingredient; FDA says supplements with DMHA are adulterated and has issued multiple warning letters.1
• Similar stimulant analogs (DMAA/DMBA/BMPEA) have also been targeted by FDA for safety concerns in supplements—illustrating the “swap-one-chemical-for-another” pattern.1–2
• Eria jarensis products have repeatedly tested for N,N-dimethyl-PEA (a methamphetamine-like stimulant) and labeling is often inaccurate. Some regulators abroad restrict N-phenethyl-dimethylamine in foods.3
Parent tip: Watch for labels listing DMHA, 2-aminoisoheptane, 1,5-dimethylhexylamine, Eria jarensis, BMPEA, DMBA, DMAA, hordenine, or high caffeine — all red flags.
Why it’s risky:
• Corydalis contains tetrahydropalmatine (THP); case series link it to drug-induced liver injury (hepatotoxicity).4–5
• Some listings even add lidocaine (a numbing medicine) to “feel” the product; oral lidocaine can cause seizures, dangerous heart rhythms, and has been fatal, especially for kids.16–17
Parent tip: Avoid any ingestible product boasting a “numbing” sensation.
Why it’s risky:
• Huperzine A is a potent acetylcholinesterase inhibitor (drug-like). Side effects include nausea, vomiting, diarrhea, and it interacts with other medicines.15
• Kanna (Sceletium tortuosum) affects serotonin reuptake; mixing with antidepressants or other serotonergic agents raises serotonin-syndrome risk.14,13
• Stacks often pair PEA, caffeine, and guarana, which can push heart rate and blood pressure and are frequently under-labeled for total caffeine load.11
Parent tip: “Brain boosters” that combine stimulants + Kanna + Huperzine A are drug-like without medical supervision.
Why it’s risky:
• Phenylethylamine (PEA) is a potent stimulant that spikes dopamine and norepinephrine but breaks down rapidly—leading to a fast high and sharp crash. When mixed with caffeine or Kanna, it increases the risk of anxiety, agitation, or hypertension.14
• Kanna (Sceletium tortuosum) alters serotonin reuptake and should not be combined with antidepressants, MAOIs, or other serotonergic agents due to the danger of serotonin syndrome.14,13
• Huperzine A is a drug-like acetylcholinesterase inhibitor, meaning it affects brain neurotransmitter levels similar to prescription memory medications; side effects include nausea, vomiting, and dizziness.15
• English Walnut Bark extract has MAOI-like properties, which may dangerously amplify stimulant and serotonin effects when combined with PEA and caffeine.13
• 85 mg caffeine per serving (and likely underreported totals) can elevate heart rate and blood pressure, particularly in adolescents or people sensitive to stimulants.11
Parent tip: “All-natural” doesn’t mean safe. This kind of “next-generation focus” stack mixes multiple neurotransmitter-altering compounds—essentially mimicking prescription stimulants without medical oversight.
Why it’s risky:
• 5-HTP (serotonin precursor) can interact with antidepressants → serotonin syndrome; poison centers warn about this.12–13
• Guarana concentrates very high caffeine (2–8% in the seeds), which stacks with other sources.11
Parent tip: If a “mushroom” capsule also lists 5-HTP or guarana/caffeine, treat it like a mood-altering stimulant mix.
Why it’s risky:
• Shilajit is a tar-like exudate scraped from Himalayan rocks and often contaminated with heavy metals (lead, arsenic, mercury) when unpurified. Even so-called “purified” products frequently test above safe limits in independent lab analyses.10
• It contains fulvic acid and dibenzo-α-pyrones, compounds that can alter hormone levels and blood pressure. Unregulated doses may trigger testosterone spikes, liver strain, or blood sugar fluctuations.
• Unstandardized sourcing is a major issue—Shilajit varies wildly by region and vendor, with no consistent chemical fingerprint or clinical dosing standard.
• It’s often marketed as a “natural performance enhancer” or “male vitality resin,” but clinical evidence is minimal, and adulteration with steroids or synthetic drugs is well-documented.
Parent tip: “Shilajit” may sound ancient and earthy, but what’s really inside can be rock sludge laced with metals. Products sold as “mountain tar for stamina” are unregulated, untested, and potentially toxic—not ancient medicine.
