As an INTP, drugs serve varied purposes:
(explanations in terms of cognitive functions, as that is how one actually engages the substance of the MBTI)
classical psychedelics: explosion of creative and abstract cognition, also breaking through my tendency toward disengagement with a world that seems flat and pointless. Ti launches in new directions, and Ne makes a surprise appearance.
stimulants: Ti sent into overdrive augments the rewards of my usual style of cognition, and I finally feel genuinely excited....I still fail to adeptly direct/organize the external, empirical world though. I sometimes wish I were prone to 'tweaker-clean'.
entactogens: magical! These unlock ability to actually read emotions via non-linguistic exchanges and also generate meaningful introspection into my emotions. Fe becomes competent, and Fi makes an appearance.
benzos or opioids: evaporation of anxiety effects motivation and comfort, socially and otherwise.
dissociatives: a mixed bag....cognitive dissociation facilitates ability to break out of the rigidity of the conceptual structures my Ti has built over the years. However, they can be annoyingly confusing and too emotionally flattening--I'm flat enough by default. Also, they exacerbate the somatic disconnection that I experience sober.
