Dose - MDEA and Tolerance

[Joel90]

So, on the weekend, some people I don't know found something that was most possibly MDEA, cause their kick was like three hours, they felt a bit less loved up, and the ones that took high doses all hallucinated slightly.

Soon, they plan on finding some more pills. However, one of them asked me a question: Because the pills they had been finding over the last few months were for the same source, they may have all been MDEA. Say that source starts selling MDMA. Say that they had been building a tollerance so MDEA for a while. Say they take the dose they had been getting used to, but this time it was MDMA!

Sorry, this is getting confusing.

If you eat a fuckload of MDEA, will that somehow build your tolerance to MDMA aswell?
