I got quite the list here haha.
For spiritual, life-changing purposes- Ayahuasca, Iboga, Ganesha, and Mescaline.
For novelty-purposes or because the drug is a category of compounds I love (i.e. dissociatives): Opium (had it before, wanna try out without IV smack addiction like then hah), smoked PCP or nasal "angel dust" at the right/lower dose to enjoy the dissociation, 3-MeO-PCP more so than PCP because it's supposedly warmer like MXE so I've heard (via IM, oral/sl, nasal, and smoke/vaped, because I've always wanted to smoke PCP, 3-MeO has it beat I'm sure) LSZ/AL-LAD- because of love for LSD and ergoloids; spirituality and psychedelics go hand in hand with me to an pretty huge extent after a DMT break-through, 2C-D- for it's nootropic properties, LSA- unique organic cousin to LSD despite the bodyload, I'd also use via mgs; also very spiritual and related to Shamanism, 5-MeO-DMT, Bufotenin/5-HO-DMT- beyond just interested in this one haha.
Psychedelics, Euphoric, Empathogenics, and interesting drugs: 2C-E intense mescaline-like psychedelia I've heard, Methaqualone, 2C-I gentle phenethylamine subtle psychedelia and nootropic-like stimulation, 2C-B the classic 2c-x! Flunitrazepam, Nimetazepam, Lormetazepam, Bromazepam, GHB, Midazolam, Triazolam, Loprazolam, IV higher-dose than I did of Hydromorphone, IV Opana, Plafium, Diconal, IV pharma-grade Diamorphine, 5/6-APB for similarities to MDA, 4-HO-MET, pure form of Baeocystin a "gentle psychedelic" in some strains of shrooms, Butyr-Fentanyl for my enjoyment of Fentanyl and the TR Jesusgreen wrote on it, 5-MeO-MiPT, 5-MeO-DiPT, Diphenidine and MXP/2-MeO-Diphenidine because it's a dissociative and I love me some disso's, IV 4-MMC, ect.
