I have had it back in the day.
I never purchased it though, the only reason was because I was using meth, taken orally, and was content with that feeling.
Regarding the methcathinone, it is very euphoric, a lot of pleasant body warmth, an above average "kick" when insufflated, lasted about 20 odd minutes and then lingered and this was actually sufficient.
But in that mindset, the desire to have "another line" is intense.
It will be taken again if there is any left.
The next line would give a very close feeling to what the first one did..... rinse and repeat until it is finished - this is actually one of the situations where oral meth, at that time, saved me from "fiending" for more CAT.
It was in my thoughts regardless (a distraction that wasn't warranted).
The friends that didn't want to take any meth orally or had their preference for methcathinone, became extremely addicted to it, and in a negative way.
I fully understand what they must have gone through.
If someone offered some to me right now, after not taking meth or any street drugs for more than 10 years, I probably would jump at the opportunity, this might sound strange, but I am just being honest.
Knowing the risk it comes with, only if it was offered, I would accept.
This will never happen though, as my life is in another "lane" now, and there isn't anybody I associate with that would offer me any drugs. Except alcohol, which I don't partake in.
Bottom line is, if it was there, I would want to partake in it. Right here and right now.
It is extremely "morish" , similar to Crack "morishness", but in my case it felt "cleaner", as dumb as that sounds.
Conversely, if I was offered Meth, I would reject the offer. (This might sound weird to everyone, but am adding it for purpose here).
So to answer the question in the title of this thread, yes, I have tried it and loved it.
As regarding Harm Reduction I would never advise anyone to use it.
