Ibogaine Schedule I

What it is & how it's thought to work

A plant-derived compound that acts on many brain systems at once and raises BDNF (a growth signal for neurons)³; used mainly for addiction and, increasingly, TBI/PTSD in veterans¹.

Why people try it Plausible

A Stanford study of 30 Special Operations veterans reported large improvements in disability, PTSD, depression, and anxiety — striking, but early and open-label¹.

The honest risks Established

Its defining danger is the heart: it prolongs the QT interval and can cause fatal arrhythmia, at normal doses, even without prior heart disease, with risk lasting days^2,3,4. Your body's CYP2D6 enzyme also determines your exposure — some people get double the dose effect⁵.

MDMA Schedule I · late trials

What it is & how it's thought to work

A compound that increases serotonin and promotes feelings of safety and connection, studied primarily to help people process trauma in PTSD therapy.

Why people try it Plausible

It appears to lower fear and defensiveness enough to make trauma processing possible; late-stage trials have targeted PTSD.

The honest risks Established

Because it floods serotonin, combining it with SSRIs, SNRIs, or MAOIs risks serotonin syndrome — a medical emergency. It can also cause dangerous overheating, low sodium from over-drinking water, and raises blood pressure/heart rate⁶.

Ketamine / Esketamine Schedule III · legal off-label

What it is & how it's thought to work

An anesthetic at higher doses; at lower doses it produces a dissociative state and rapidly boosts neuroplasticity, used for depression, suicidality, and PTSD. Esketamine (a nasal form) is FDA-approved for treatment-resistant depression.

Why people try it Plausible

It can lift severe depression and suicidal thinking quickly — sometimes within hours — which is why it's the most medically accessible of these options.

The honest risks Established

Acute dissociation and a temporary rise in blood pressure/heart rate. With repeated or frequent use, two concerns grow: bladder damage ("ketamine cystitis")⁷ and dependence/abuse potential.

Psilocybin Schedule I · trials / some states

What it is & how it's thought to work

The active compound in "magic mushrooms," which acts on serotonin 5-HT2A receptors and promotes neuroplasticity; studied for depression, alcohol use, PTSD, and end-of-life distress.

Why people try it Plausible

Controlled trials show real benefit — for example, a randomized trial in alcohol use disorder found significantly fewer heavy-drinking days, with no serious adverse events from psilocybin⁸.

The honest risks Established

Medical risk in controlled settings is relatively low^8,10, but the psychological risk is real — it can destabilize people with a history of psychosis or bipolar disorder — and it transiently raises blood pressure/heart rate⁶. Rarely, lingering visual changes (HPPD) occur¹⁰.

LSD Schedule I

What it is & how it's thought to work

A potent, long-acting serotonergic psychedelic studied for anxiety and depression; mechanism is similar to psilocybin but the experience lasts much longer (up to ~12 hours).

The honest risks Established

Medical toxicity is generally low in controlled settings, but the very long duration magnifies psychological demand; risks include destabilization in vulnerable people, HPPD, and transient high blood pressure¹⁰.

Cannabis (THC / CBD) Schedule I federal · many states legal

What it is & how it's thought to work

Acts on the body's cannabinoid system; THC is intoxicating, CBD is not. Used by many veterans for PTSD symptoms, pain, and sleep — legally in many states, though evidence for PTSD specifically is still limited.

The honest risks Established

The clearest risk is psychosis: reviews show a dose-dependent increased risk, earlier onset, and worse course — especially in those with a personal or family predisposition⁹. Also: increased heart rate/cardiovascular strain, dependence, and, with heavy chronic use, cannabinoid hyperemesis.

Kratom (Mitragynine) Unscheduled federally · varies by state

What it is & how it's thought to work

A Southeast Asian plant whose alkaloids act partly on opioid receptors; often self-used for opioid withdrawal, pain, and mood. It is not a psychedelic — but it's widely used in this same population, so honest education matters.

The honest risks Established

It carries a real risk of dependence and withdrawal, liver injury, seizures, and life-threatening toxicity — especially when combined with other drugs¹¹. "Natural" does not mean safe, and it is unregulated, so product strength varies wildly.
