Summary
3-MAR produces a clear, focused stimulation reminiscent of 4-MAR but with more pronounced head pressure and emotional lability. Users describe strong synergy with amphetamine yet diminishing returns when redosed in isolation. Nasal administration is sharply caustic; vaporizing the freebase yields a rapid rush but encourages compulsive re-administration.
Dose Information
Dose basis. Ranges are compiled from scattered user reports and analog extrapolation (not clinical data). Potency may vary by isomer ratio (cis/trans) and salt vs freebase. Start low, titrate cautiously, and avoid rapid redosing. User reports describe notable causticity and mucosal irritation with aminorex analogues; dilute finely, avoid repeated back‑to‑back lines, and rinse gently with isotonic saline post‑use. (Dose figures and this note are from Drugs.Wiki.)
| ROA | Light | Common | Strong | Heavy |
|---|---|---|---|---|
| Oral | 5-10mg | 10-20mg | 20-35mg | 35mg+ |
| Insufflated | 3-7mg | 7-15mg | 15-25mg | 25mg+ |
| Smoked | 2-5mg | 5-10mg | 10-20mg | 20mg+ |

Effect Profile
Scores (1–10) curated from multiple sources:
- Effect keyword matching from PsychonautWiki catalog
- Weighted by importance: core (×3), major (×2), minor (×1)
Strong anxiety/jitters with moderate stimulation, mild euphoria and focus
Tolerance
Tolerance Decay
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Anecdotal: tolerance rises rapidly during a binge and partially recovers after 3–5 days; baseline by 7–14 days if no further use. Cross‑tolerance with other aminorex derivatives and common stimulants is likely but unquantified.

Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track 3-MAR there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
3-MAR Source: SubstanceSearch (substancesearch.com) Oral dose (mg): threshold 5 · light 5-10 · common 10-20 · strong 20-35 · heavy 35+ Insufflated dose (mg): threshold 3 · light 3-7 · common 7-15 · strong 15-25 · heavy 25+ Smoked dose (mg): threshold 1-2 · light 2-5 · common 5-10 · strong 10-20 · heavy 20+ Oral duration: onset 20-40m · peak 0.5-3h · offset 2-6h · total 2.83-9.67h · after-effects 4-24h Insufflated duration: onset 5-10m · peak 0.5-3h · offset 2-6h · total 2.58-9.17h · after-effects 4-24h Smoked duration: onset <1-2m · peak 0.5-3h · offset 2-6h · total 4-12h · after-effects 4-24h Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.
Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 15 mg (Oral).
The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.
