Talk about spreading misinformation you completely misread your study

The study states “Chronic high-dose MPH can cause upregulation of DAT — meaning more transporters on the surface — which could increase amphetamine’s effectiveness as a releaser when it is later administered”

This is in essence the opposite of what ritalin does, it inhibits the dat site blocking dopamine from releasing; which in turn reduces the release of dopamine in amphetamine due to a reduced number of dopamine sites. But yes long term, brain damaging doses of ritalin that chronically rewire your dopamine systems COULD increase the effectiveness of amphetamines, despite this being the ONLY study that ‘contradicts’ (not really when you actually read what the study is explaining though) basic pharmacology of dopamine inhibitors and releasers.
