Ik hoorde uit diverse hoeken dat MDAI totaal niet schadelijk is voor de hersenen op de lange termijn. Daarbij zou het spul ook geen cross tolerantie hebben als je een week later 4-fa of MDMA pakt. Kan iemand dit bevestigen uit ervaring?
Serotonin neurotoxicity in rats after combined treatment with a dopaminergic agent followed by a nonneurotoxic 3,4-methylenedioxymethamphetamine (MDMA) analogue.
Monoamine and metabolite levels and the number of 5-HT uptake sites (using [3H]paroxetine binding) were determined 3 hours or 1 week after treatments. Combining the monoamine oxidase inhibitors, clorgyline (MAOA selective) or deprenyl (MAOB selective) with MDAI did not result in any long-term reductions of serotonergic markers. Similarly, combining the DA uptake inhibitor GBR-12909 with MDAI did not result in any long-term changes in monoamine levels at 1 week. In contrast, a single pretreatment of posttreatment with the nonvesicular DA releaser S-amphetamine and MDAI resulted in small but significant long-term changes in monoamine levels. More importantly, if a subacute dosing regimen (every 12 hours for 4 days) was utilized, the combination of S-amphetamine with MDAI resulted in a marked long-term decrease in the levels of cortical, hippocampal and striatal 5-HT, 5-HIAA and the number of 5-HT uptake sites.
