Honestly, these questions are in general quite difficult to answer, as we will be for the most part trying to infer from animal experiments involving a very high dosages given a small number of times over a brief period to humans taking comparatively low dosages at higher rates of frequency over long periods. However, there are some notable general trends:
Neurotoxicity: methamphetmaine might be the most neurotoxic of typical classical stimulants. Compared with amphetamine, it induces toxicity (largely through oxidative stress) at lower dosages (certainly having measurable effects when taken in dosages over 20 mg). While it is not entirely clear why this is, it seems that part of what's going on is methamphetamine's higher lipophilicity allows it to more easily diffuse into the presynaptic cell directly, wherein it is more likely to affect the cell's functioning and to be metabolized to oxidative species. So at equi-intoxicating doses, amphetamine will be much safer, and NDRIs will essentially be absent of neurotoxicity. Additionally, meth's affinity for SERT and propensity to release large amounts of dopamine confer the type of serotonergic neurotoxicity that we see with MDMA and other entactogens, albeit milder...well, milder until one binges (as is common with meth). In behaviorally relevant terms, it is really difficult to establish a certain "safe" level. Given that the serotonin system is strongly affected, I would try to adopt once monthly or more infrequent dosing if the doses are high (especially to the point that there is dosing following a night of lost sleep), perhaps a bit more frequent dosing with lower dosages. I can't really see dosing more than once a week being prudent in any sense. One thing that has come out more clearly in the epidemiological data is that regular dosing of either meth or other amps significantly increases Parkinson's risk, due to dopaminergic toxicity localized to the striatum.
As for other organs, meth places significant train on the kidneys, and opulent hydration is key. Luckily, meth doesn't place particularly much train on the liver (beyond general metabolic increase and the other lifestyle correlates that come with regular use). As for cardiotoxicity...well...honestly, I wouldn't really use any classical stimulant with any regularity past age 40. The strain gets more and more apparent as one goes on. The cumulative toxicity seen with regular usage is pretty closely analogous to the damage conferred by a tobacco habit. . .
Hope this helps (sorry it was so vague...)

Thanks for this answer!!
I have a much better idea now.
