You mean if you already ate some, you're considering trying to snort some to give you like a stimulating boost.....hmmm, I don't know that it would do that for everyone, it's possible...
A little bump of meth intensifies the MDMA, boosts your energy and prolongs the roll big-time! If you're in europe though, that might be difficult to come by and I wouldn't mix any other stimulant other than meth with MDMA, the synergy is really something special unique to that combination, I believe.....
Taken occasionally, meth has a lot of the properties of MDMA while also being a very different drug, afterall meth is "MA"
