Mephedrone and permanent memory damage

[rimbaud12]

Does anyone have an opinion on or knowledge about this article?

Basically, it suggests that mephedrone may cause lasting or permanent memory damage, based on behavioral experiments with rats.
I haven't used stimulants for months, and haven't used mephedrone for almost four years. In fact, I was never a regular user of it - but had a couple of times where I consumed almost 5grams over 3 days.
Sorry if this questions smacks of anxiety (one of the reasons I stopped using stimulants is, they seem to have left me with something of an anxiety problem). But is this study on rats, which were only 3 weeks old, really relevant to humans? Does it mean that, in contrast to, say, MDMA, cognitive damage from this drug could be irreparable? And does it mean anything that, despite the behavioral change in the rats, the scientists couldn't find any difference or damage physically to their brains?
Also, if I had suffered memory damage, would I have noticed it? In truth, I never noticed any significant changes to my memory, now or then.
Sorry if this is the wrong place to post, first time using bluelight. Any opinions would be much appreciated

Kind of interesting, I'm not so sure it's completely relevant or irrelevant to humans. It seems like it really depends on how often and how much you're taking it. Unless you're taking 30 mg/kg (for a 120 lb person, this is 1620mg) every day, I wouldn't be too concerned about memory loss especially because it doesn't seem to be very long lasting (5-7wks) and therefore not permanent according to the study.

I can't say I've read through every post, but the Mephedrone-long-term-negative-effects-progress-reports thread might have some relevant information for you.

I suffered psychological effects for 6 months after taking Mephedrone regularly for 4 months. In my area there were a few deaths unfortunately, some were cases where the users immune system was already weak. Pretty much if you never had a life threatening occurrence on Mephedrone you really shouldn't worry, I haven't taken it for 3 years and feel fantastic, however the immediate effects of cutting the drug were horrendous. Complete psychological madness, however it passed and relatively fast. Its easy to trick yourself into long time fears, with a healthy mind, diet and exercise you can better your life and forget about the past.
