I'm assuming you are american, and in that case, speed = meth.
BTW, TrippinTreeToker -- are you off your rocker? You said that "meth is the only high that compares to mdma, its very similar but without the trippy thinking patterns(more descriptive word?)" That is total bullshit. Neither mdma nor meth cause "trippy thinking patterns". Perhaps you were thinking of MDA.
Meth IS quite addictive, but psychologically, not physically. You just need to make sure that you never have too much of the stuff lying around, and try not to do it more than once a week. That should prevent any addiction from developing.
As for comedowns, if you do meth orally, which is the most euphoric and similar to MDMA, the comedown is not that bad at all. If you make sure to drink enough water, you will be better off as well.
The high is less overwhelming, and somewhat less lovey-dovey than the MDMA high, but otherwise pretty similar. You do get a body high/sensitivity, alertness, euphoria, talkativeness, feeling social, restless, etc. It is just less intense, except for the restlessness and speeded up feeling, which is increased with meth.
