The dose an ordinary person (not a regular abuser) would take.

Coke is not equal (I mean it is arguably zero harm if taken rarely, but pretty addictive and serious harm if taken regularly), MDMA and meth are extremely similar substances chemically (MA=meth) and have similar mechanisms of action. Same harm prevention techniques work great with both. The most important difference is MDMA being harder to abuse than meth is, because a number of reasons. Most of MDMA users take it occasionally for good, most of meth users take it regularly for harm. AFAIK. Obviously there are many exceptions.

I would argue that MDMA and methamphetamine, while slightly similar in chemical structure, have very different mechanisms of action. Methamphetamine, at high enough doses. This is why dose is important, some recreational doses will cause dopamine efflux from the dopamine uptake transporter but MDMA does not do this

Doses are incredibly portant when discussing the mechanisms of drugs and comparing them because a compound may interact with new and different proteins when the concentration gets high enough. Recreational doses for methamphetamine and cocaine are all over the place partially due to the fact that you can develop tolerance and increase your dose. This doesn't really happen with MDMA as much, and while you can take repeated doses they will rapidly stop working if taken within a small enough time frame. Methamphetamine and cocaine do not have the same tolerance build up

While cocaine is a triple reuptake inhibitor and does interact with serotonin, I don't think its comparable to MDMA
