So finals season is coming into focus and I have quite a bit of work to do (books to read, papers to write, exams to study for, etc.). Usually around this time of year I will just find myself a few nights supply of adderall and get cracking with extreme focus and clarity.

Summary
Propylhexedrine (also known as Benzedrex and Obesin) is a stimulant substance of the cycloalkylamine class. It is a structural analog of methamphetamine. Propylhexedrine is widely used medicinally as a nasal decongestant (for relief of congestion due to colds, allergies and allergic rhinitis) and sometimes used recreationally as an over-the-counter "legal high".

TL;DR: Second time doing propylhexedrine ever, after a failed attempt in early 2019. Basically stayed up all night (8:34 AM as Im typing this) drawing NSFW art and talking to friends. A bit of a ramble-y report, due to the nature of the drug class it belongs to LOL.
Time of Experience: Early January 2020. Age: 19 Weight: 143 pounds Height: 60 Previous Drug Experience: Cannabis, caffeine LSD, 1P-LSD, diphenhydramine, dextromethorphan, 4-HO-MiPT, 4-HO-MET, 4-AcO-DMT, MDMA, kratom, Salvia divinorum, hawaiian baby woodrose seeds (LSA), nicotine/tobacco, alcohol, cocaine, heroin, code...
I regularly write down my experiences with different drugs and highs because I want to remember all the important parts of them and if I would want to try them again. I'd like to start this off by saying I'm regularly an incredibly unhappy person who will go to great lengths and a huge effort for a high.
Propylhexedrine - Trial 1 - Date: 11/26/2016 Background Information: Currently living in a nursing home expected to be released soon to a group home. The Propylhexedrine was obtained from an over the counter inhaler, Benzedrex. The Propylhexedrine is cut into four pieces and then ingested.
**NOTE** Everything that I say here in my experience report is from my personal experience with the drug. I often make reference to other stimulants. NOTHING I say should be interpreted as being applicable to others. Every body is different, so everyone reacts in unpredictable ways.
I have tried Benzedrex inhalers many times before this experience. I used to be addicted to adderal, and I loved the speedy feeling. Benzedrex seemed to be the perfect substitute, until this happened. I was at home from college on a break when I stopped and picked up the inhaler.
I've tried benzedrex inhalers a few times. They keep me awake and alert and on occasion I've felt desperate enough to resort to them. I am an occasional recreational user of hard drugs. I do not use stimulants regularly. One day I decided to take 200mg of pure MDMA on a school night and stay up pretty late.

It was the end of august, I had just learned about benzedrex nasal inhaler a little bit ago by my best friend ever. Prolly would say i tryed it about end if august. I feel in love with this drug as soon as I did it. This thread is going to be a trip report. I would love hearing any crazy, and wild Benzedrex story's.
I took an unknown amount of Propylhexedrine (Henceforth PHX) acetate (Extracted in vinegar) equivalent to 250mg PHX, one wonderful, delicious, long, Romeo y Julieta Churchill length Cuban Cigar (If I had an unlimited supply of these, I don't think any other psychoactive would be in my safe, it is my one true love ), an...
PREFACE: A Diamond in the Rough? I have never seen such polarized opinions/experiences about any psychoactive drug until I went fishing for info on legal OTC stimulants, and became intrigued by propylhexedrine (which I'll call Propyl from now on) .
Mods: please move to trip reports. Thanks. A couple of notes: I preserved some grammatical errors in here. Somehow, it seemed more true to my voice at the time. I submit this relatively mundane account just because there's a dearth of reports on propylhexedrine.
*Disclaimer , (This is my First time) I am only a consumer of Benzedrex (*Footnote: in California, it's sold in CVS/Pharmacies and Walgreens) *Disclaimer(2) I am only doing this because I recently moved into another city and have NO connects whatsoever.
(Propylhexedrine/Repeated @ varying doses) - Experienced - Little use & effect guide After many uses of propylhexedrine, I feel that I should make a guide of my own because I feel that the few of these that already exist don't tell the full story of this magnificent psychoactive.
Just thought I'd post a little sumthin' sumthin' on my first experience with Propylhexedrine, aka the mighty Benzedrex inhaler. First off just let me say that I spent the entire preceeding night researching this chemical--the pros and cons, dangers, methods of ingestion, trip reports, and anything else I could find.
