if you use nicotine pouches recreationally the effect will cease but i will actually second that, even as a current nicotine addict, when i started taking nicotine pouches (2mg), they felt like a 30ish minute adderall.
these are mid, but if you're looking for a small extra legal push:
alpha GPC, uridine monophosphate, caffeine stack. these are actually precombined (at an effective, albeit lower dose) in gorilla mind energy drinks. heard good things about huperzine also
i've heard good things about dihexa and i intend to take that for my degrading memory loss here soon, from a physio/psychoactive standpoint it would be useless though
if you're looking for something that will make you lock in, tldr adderall
