Overrated- cocaine above all, it's basically cigarettes for your nose, but with much less of a rush. Its strongest effect is creating an urge to do more. Nicotine as well, I can't believe how much time/money I wasted on tobacco when I was 18/19. Benzos, when I tried them they were pretty boring, yet so many destroy themselves with those horrid little pills. Lastly I'll say MDMA, it's far better than the other drugs I just mentioned, but I just don't get the hype. I'm all about psychedelics, I fucking love amphetamines, but MDMA just isn't my style. However I love MDA, I don't dislike rolling, hell I certainly enjoyed MDMA when I've done it, but I am interested in the more trippy/introspective/spacy side of empathogens, though don't have too much experience with them & wouldn't ever roll with much frequency.
Underrated- many psychedelic RC's. There is in fact reason to use them besides as "acid/mushroom replacements", they're all different compounds with their own values. As well, just becauase NBOMe's are highly dangerous and rather superficial doesn't mean all RC psychs are! Shit 4-AcO-DMT & DPT are as deep as it gets. And some of us just like to explore as many different sides of the psychedelic experuence as we can, while I do consider LSD psychedelic perfection that's not inherently true, everyone's taste is different and their are many psychedelics I love almost as much as good 'ole LSD. Also gotta say, with the whole dabs craze many underrate classic hashish- I prefer it to oil! May not be quite as strong, but the high is better & it's still far stronger than buds. Finally, I'd say kratom is underrated, simply because it doesn't fuck you up the way stronger opioids do, but that's not a bad thing I love how I can function 100% normally yet still be nice and high, stimulated yet relaxed at the same time, it's sort of a wonder drug in terms of functionality for me (though I need a short break soon).
