Tonight I may have taken the largest dose of Methcathinone I have ever taken. I must say that I am both surprised and pleased by what I am experiencing. I have taken this drug many times before and have never had the 'breakthrough' type of experience that I am having right now.

Summary
Methcathinone is a Schedule I controlled substance internationally and in the US. Illicit synthesis using potassium permanganate oxidation of ephedrine/pseudoephedrine has been associated with manganese-induced neurotoxicity resembling Parkinson's disease symptoms. Causes severe dehydration and increased perspiration requiring constant hydration to prevent rhabdomyolysis.

Tolerance
Build-up
develops rapidly, often within a single session; compulsive redosing common
Reset
a few days for acute tolerance
Tolerance Decay
Full tolerance
2d
Half tolerance
4d
Baseline
~10d
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.
Rapid tolerance is commonly reported with repeated use over days; rough decay to baseline over ~1–2 weeks is inferred from community reports and stimulant analogues. Data quality is limited and interindividual variability is high.

I guess it all started when I heard about a new drug craze that had just been detected in Michigan by the local authorities. I'd say it was somewhere around the middle of 1993.
I hate the name of this drug. Impossible for me to pronounce or spell. Very appropriate. A friend of a distant cousin brewed up a batch of this stuff... about 2 grams of it... and left it under a rock near my mailbox. While shoveling snow, I stumbled upon it and decided to check it out.
>Erowid Note: We aren't sure whether the substance described in the following report was methcathinone or cathinone. Last night, a good friend of mine came over. This was the same friend who initially introduced me to harder narcotics.
[Erowid Note: This report is marked as a methcathinone report, but readers should be aware there are aspects of it that suggest the identification is speculative.] When I first encountered methcathinone (erroneously called ice by the mentally imperfect oaf (read idiot) who had been using it for at least 6-8 months), I...
I was not planning on doing any stimulants that night but a chance came up to try Metacthinone. I'm always down to add another substance to my resume and in this case I was interested in the serotogenic action of this particular stimulant and how it compares to meth (the best stimulant period IMHO).
General Background: 21 year old male, once an extremely heavy user of psychedelics, particularly research chemicals. Stopped using drugs for a couple of years, after recovering from an opiate/benzodiazepine addiction catalyzed by HPPD/Psychosis (the result of reckless hallucinogen abuse).
The synthesis was initially a success, I had at least 1 gram of MCAT freebase. This is where things got a little iffy: In the absence of a suitable base for the substance, I hypothesized that I could slowly evaporate most of the water out, making a concentrated freebase solution.

Hi, new here, but a long time reader. Since the Meph ban me and my wife have been looking for something legal to take to have pleasant evenings in together, since with 2 kids, we're usually pretty shattered in the evenings, and we rarely get time together, so a little something to keep us awake and having fun all night...
Hey, hi. I don't often write on Bluelight, but I read a lot . To fill you in: I've eaten and snorted my way through an alphabet soup over the years, like many of you. And, of allll the various molecules, I tend to prefer stimulants that are euphoric.
Ecstasy - first time - IS THAT A CAT ON HER HEAD?
