Meth/MDMA cross tolerance?

[The HiVe MiND]

This is probably a stupid question, but I'd just like to make sure I'm right...
There's no kind of cross tolerance between Meth and Ecstasy is there??
Just making sure 'cause I'm trying to space my pills out monthly (for my health & tolerance levels), and might occasionaly take Meth for those times in between...
Cheers!

No, there is no cross tolerance. However, since both drugs tax your serotonin and dopamine reserves, you could get less out of your highs by using both drugs. This would not be due to tolerance -- only due to the lower neurotransmitter levels. Nonetheless, since MDMA doesn't use up THAT much of your dopamine (especially since dopamine stores redbuild quickly), and meth doesn't use TAHT much serotonin, I don't think moderate alternate or co-use would be much of a problem.
