Look up this thread's speculation on toxic metabolites of mephedrone.
IMO, if you had a medical assessment and they claimed that you'd be okay, you should be fine in time, but you just need to catabolize all that nasty 4-methyl-ephedrine, etc. Did you tell your doctor that you took mephedrone?

No, i honeslty didn't have the balls, as the doc seemed pretty tired and pissed off anyway. I know, i should of told him, but i figured like alot of people of said, he's probably never heard of meph before. He asked if i'd done any stimulants and i told him the truth and said i had, 6 days ago. Really hoping these symptoms pass in time. Had a bit of a panic attack today about the pins and numbness for an hour, ok now though.
I'd also just like to say that i know that there are those who think this drug is only damaging to people who abuse it, I think i am pretty much clear evidence that this is simply not the case. If you've tried it, had a good laugh, and not experienced what I and some others have been going through i.e chest pains and numbness in my case from quite a small first time dose. And even turning blue for others. Good for you.
However if you've never tried it before, i have to tell you that in my opinion it simply isn't worth taking the risk. If i introduced it to a friend of mine and this happened to them i would feel horrible about it, as my friend who introduced me to it now feels. To be completely honest it has had me really worried for a week now. I've had plently of fun experimenting with other substances, stuff with at least a bit of research and experience behind it, going to stick with the tried and true

.
NEVER doing this stuff again.
(PS. sorry if i got a bit preachy, but nothing has ever had me so paranoid or worried before)
