^... huh, yeah that makes sense. REALLY should've read your post fist, heh.
Affininity can result in different responses depending on the properties of a drug, and is different from efficacy. This is an oversimplification, but basically if a drug has affinity for the serotonin transporter protein (SERT) but has no efficacy it's an antagonist (it just sits their getting in the way of other drugs like MDMA or natural neurotransmitters like serotonin). For example, the SERT inhibitor duloxetine mitigates the effects of MDMA, which partially works by reversing the action of SERT i.e. releases serotonin (also, don't confuse SERT, the serotonin pump, with 5HTx binding sites, as they're different things). That's what's confusing me about the segment of the paper posted. The authors talk of MXE both having affinity for and "inhibiting" the serotonin transporter protein, which sounds like antagonism (basically it plugs up the pump [SERT] that takes serotonin back into the neuron), but then go on to suggest there is a resulting increase in the release of serotonin (which sounds like a drug that reverses the activity of the protein, thereby pumping serotonin out instead of in). But I wouldn't expect that the release of serotonin would increase (it would just keep releasing normally but reuptake would be slowed because the transporter proteins are inhibited by MXE). In other words, it seems like inhibiting SERT should increase intracellular serotonin but not cause increased release, yet they seem to suggest MXE may cause increased release of serotonin despite this.
This includes MXE, its analogues and many synthetic cannabinoidsDavid Nutt said:The UK government have published the draft for an amendment of the misuse of drugs act, adding some newly emerged drugs in as recommended by the advisory council on the misuse of drugs last year. You can read their explanation of the amendment here (pdf)
I have noticed being depressed while on the drug, even suicidal... feeling like everything is against me, and nobody likes me. I have had this 2 times on MXE. Also it seems to be a gamble sometimes, I've had brilliant glowing experiences on higher doses filled with bliss and good feelings, but last night I felt extremely uncomfortable. Walking made me ill, sitting made me ill, to the point of almost vomiting, only laying down in bed seemed to help, but I'd get the spins pretty bad, also with a headache and a feeling of being twisted and insane. These were all around the 70 mg mark. 40 starter and top off with an hour later. Very strange...
I noticed that, if consumed frequently, after stop using MXE causes depression (more likely - the depressive phase maniac-depressive illness) for an indefinite period of time.
Anyone willing to confirm that?
I get what you are saying about purging of the senses, I felt sad while on it, but when the experience ended it lifted inmediatley, and I felt better then normal. In my case it was definitley depression (thinking in negative ways about anything) but it did felt like a "release" of some sort. What strikes me as odd is that I seem to be one of the very few who can sleep on MXE. I would even go as far as to say I actually like sleeping on it. I have dozed off and fell asleep holing a few times, only to wake up 4-5 am to piss and I'll be still heavily tripping.
That sounds like a lame experience man. No offence but if I was getting these effects I would just quit. After some experiences I really think this shit has the capacity to make you batshit insane.
MXE has no affinity for dopamine, only serotonin and NMDA.
