Summary
DMHA is a synthetic sympathomimetic stimulant originally developed as a nasal decongestant in the 1940s-1950s. The FDA considers DMHA an unsafe food additive and has issued warning letters to supplement manufacturers. It is banned by WADA for athletic competition and is illegal in several countries including Australia, Canada, and parts of the EU.

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 focus and anxiety/jitters with mild stimulation and euphoria
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.
Estimates reflect stimulant-class tolerance patterns inferred from user reports; high uncertainty.
