Near and in Maryland it is very popular. Smoked the crystals habitually for two years. Often melted with tobacco, snorted or swallowed. Every time same side effects. Vomiting nonstop. Hyperventilating like crazy. Heart pounding. Headache for days so bad I would bang my head to relieve the excruciating pain.

Summary
Eutylone is frequently mis-sold as MDMA in festival and party settings globally. It produces stimulant and empathogenic effects but with shorter euphoria and more pronounced comedown, including anxiety and headaches. In 2021, eutylone was the most commonly identified cathinone by the DEA.

Description
Eutylone Source: SubstanceSearch (substancesearch.com) Oral dose (mg): threshold 15 · common 50-80 · strong 200-300 · heavy 300+ Insufflated dose (mg): threshold 5 · light 15-45 · common 45-80 · strong 80-125 · heavy 125+ Oral duration: onset 15-45m · come-up 15-30m · peak 2-4h · offset 0.5-1.5h · total 4-8h · after-effects 2-4h Insufflated duration: onset 15-45m · come-up 15-30m · peak 0.5-1h · offset 0.5-1.5h · total 3-6h · after-effects 2-4h 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 ~ 65 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.
Tolerance

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-style acute tolerance and mood depletion based on user reports; robust human PK/tolerance datasets are lacking. Space uses by several weeks for recovery, especially sleep and mood.

I’ve used Eutylone (N-Ethylbutylone) 3 different times now. I thought I’d post my most recent experience. Overall I’d rate it as quite lack-lustre, even mildly unpleasant.
