And I have heard that Cocaine's neurotoxicity is very similar to Ritalin,
^
Coke will not cause neurotoxicity.
^QFT. M(A)RIs (monoamine reuptake-pump inhibitors) are enthalpy driven; actually shown to be neuroprotective; also studies show that abusers of cocaine have less instances of Alzheimers than normal, non-drug-abuser neurotypical control-study-pool individuals, statistically, but amphetamine abusers (a MRA; monoamine releasing agent; it's method of action is entropy driven; phosphorylating and internalizing the transporter) have higher life-long chances of running into the Alzheimers disease progression.
Ultimately Ritalin is probably the safest bet.
thank you for the suggestions. I'll research ritalin.
Ritalin is a controlled substance (diverted pharmaceutical without an Rx, etc) in many places (for instance, the USA from whence I hail), but there are grey market (legal as long as not touted as a cure, medicine, mind-altering substance or etc. i.e. a legal grey area, not technically illegal but find the proper lawyer to construe this or that analog act and....) analogs that could be better in some capacity, esp. the legal one;
Of course, the above is not on par with the question so I bundled it, just a colloquial experience abusing an MPH analog in a more extreme manner than the OPs consideration of its use for. However, when I speak of MPH analogs, I think of the differences in monoamine affinity over methylphenidate (that is the generic name for Ritalin) like for instance methylnaphthylidate, they are more serotonergic and that may be something that is desired for easing come downs generally. Cocaine actually hits 5-HT transporters (SERT, the serotonin transporter) fairly well, the same is true with methamp, but not Ritalin, so considering a variant that takes that into account is probably my suggestion here. I wrote the WP article on MPH analogs, just updated it the other day, in fact.
