I'm truly glad that the speech problems subsided with abstinence.
I was once asked if I was dyslexic by a new guy at work when I had been over indulging in molly. That was awkward. So it does get pretty fricken bad...
One thing that barely recovered, even with a 10 month break from MDMA and all stimulants, was my once amazing working memory and long term memory. I used to get commended on my memory, but would now be lucky to have 50% of what it was. Even when smoking weed all day, every day, I never used to forget names and had a mental phone book of important numbers, but that is now long gone. To a lesser extent I still suffer from difficulties when problem solving and find it much harder to learn new things. I used to pick everything up like a sponge and now I sometimes find myself really having to try to learn stuff.
I'm definitely not dumb, but my abuse of MD** substances surely dulled me down a few shades from where I should be.
I did notice similar side effects when abusing amphetamines from time to time, but they were a lot less prominent. It's interesting that meth is more neuro toxic than MDMA and I found it to cause less cognitive problems. The addiction potential is certainly higher though.
You have to take the good with the bad and one thing that increased with all my drug use is my ability to create music. I don't regret that. I have learned a lot of valuable lessons and I've had a hell of a lot of fun.
If I could go back and do it again, I would take more precautions to lessen the damage and would not take MDMA more than once a month.
The people that are still buying pills/caps in these dark times, don't really have to worry about this. There isn't enough active in them to cause these problems. It will be interesting to see what the future holds for people who continue to ingest the likes of pipes and any number of barely studied/unstudied research chemicals such as the beta ketones
Only time will tell
