INTP or INFP. Most tests show INTP and I think that is correct, though the thinking/feeling sides are reasonably balanced.
My top three favorite categories from high to low:
Psychedelics - LSD, Mushrooms, DPT, 2C-E, DMT, DOC, and Ketamine are my favorites. No particular order.
MDMA and similar
Opiates - The stronger, the better though I've really only used poppies, hydrocodone, and codeine a lot - often high doses. Oxycodone a few times. Preferably mixed with downers. These are what I use the most of.
I love cannabinoids and use them a lot. I'd rate them below opiates.
I like stimulants quite well at times, but they just don't interest me most of the time.
There are few drugs that I don't like (alcohol, for example).
