in all my ranting i forgot my main point... see what bing stoned does to ya :P lol

the 'natural high' of meditation is literally just that... during meditation / spiritual exercise, your brain produces a bliss chemical called anandamide(s), which act on a very specific set of receptors

cannabis and chocolate are the only external stimuli containing compounds which act on these same receptors

theoretically then, one could argue for either side of this issue with ganja in meditation.. cannabinoids either aid in the process because they use the same receptors, or interfere with the process for the exact same reason

i stick my by original statement that it is a little more complex than just good/bad, but it isn't for everybody, and in my opinion should not be an integral part of daily meditation, but can aid in the process
