i find the attitude "mdma is so good and pure and clean and those other drugs are pure garbage" irritating in its simplicity and dualistic thinking.
mdma is indisputably neurotoxic to some degree. both drugs have different appeals and negative side-effects, and much be judged individually by a prospective user, but to say that either one is beautiful or ugly and evil seems naive.
i prefer 4mmc to mdma because it gets me far far higher, i dont feel as fucked up or cloudy, i can dance better on it, and i find the comedown far more bearable, as i get terrible depression from mdma.
4mmc does tend to be habit-forming psychologically because redosing works much more effectively and can be strung out longer, so perhaps 4mmc requires more willpower to use in a responsible manner. also the fact that the high is just so good. it feels like what i wish doing coke + molly was like.
there are many reports of serious cardiac issues and vasoconstriction, but i know many people who use 4mmc and none of them have experiences these to any degree that would be cause for concern/hospitalization. i have to wonder whether these issues are really that much more likely to result from 4mmc use than other stimulants such as meth and cocaine.
of course, the academic research is just not there, and this gives one pause for concern. however what work has been done doesnt appear to pin 4mmc as significantly worse than other stimulant drugs of abuse.
there are some other pros and cons of both, including availability and purity issues. my main point is, between mdma and 4mmc one isnt good or bad, neither is good for you, do the research and decide for yourself.
methylone is a really nice 4mmc alternative, appears to be less neurotoxic than mdma or 4mmc, but snorting doesnt work very well. if youre planning on eating your drug anyway, M1 is the best way to go as far as mdma substitutes. i like it more than molly personally.
