After reading the post about the hypothesized research chem actually being MDMA I have some food for thought:
When I was 14 or 15, I got drunk and was still pretty inexperienced. I ended up going to a park in the middle of the night and taking 4 bong rips, and this was only the second time I had smoked. Anyways, I freaked out that night and was convinced it was laced. I was confused, seeing mildish hallucinations. At one point I was riding in a car coming in and out of consciousness, when I would "wake up" I would be in the middle of yelling at someone and have no idea what I was doing or saying.
Anyways, I ended up having the worst sleep of my life, so nervous about what I had ingested. The entire next day I was having panic attacks, at one point a horse race came on the TV, my heart started racing so fast I had to turn it off. Couldnt sleep, my brain was in a fog, I couldnt talk to my parents, it was terrible. The next day I still felt jittery. I talked to my friend later that day and he let me know that it definitely wasnt laced, everyone was fine that night I just freaked out.
I searched online after talking to him, and found out that smoking weed cannot permanently damage your brain like I felt it had, and the next day I woke up feeling 100%.
My point being - Your body can have extreme reactions, panic attacks, brain fog etc, etc, etc - all as a result of constantly worrying, being stressed etc. If you wake up expecting to feel like garbage, your probably suddenly not going to feel on top of the world.
As a side note - Ive taken molly well over 20 times in my life - and as much as ~1 gram in a day - average of about 5 points for a rave. My most recent time was 7 months ago, I smoked a joint half way through the night and had a major freakout - totally dissociated - hallucinated - lights too much to handle, decided I was done with it for good after that.
I never worried about long term damage, and while I may have had a down day here and there, I felt and still feel normal. If I was on here reading horror stories, I know I would have worried, stressed, and noticed symptoms that may or may not be as real, or may be real but be a side effect of constant worry/stress.
If when I was 14, I went online and read that weed can possibly cause long term brain damage, I very well may have had panic attacks and brain fog for months.
Most research on MDMA points (no pun intended) to long term recovery from even moderately heavy usage. I would encourage you all to base your concerns less on hearsay and try to do as much research asyou can on NIH or other credible medical sources. That being said, I haven't read every page of this thread, so I am not sure what has been said in here and certainly don't want to offend anyone.
