IV Heroin- But even more so the ever prominent "fentadope" in my hood or in other terms fentanyl-laced heroin. People are dropping like flies.
Oxymorphone- Ultra fucking potent opioid, like oxy and heroin had a perfect baby. Euphorically stimulating and pro-social rush that drifts into a better nod than heroin with MAD legs.
IV Dilaudid- The fucking "crack of opioids", heavy, warm, and madly euphoric rush, but almost no legs and one of the worst opioids to get hooked on other than fentanyl.
Alprazolam- It's been known to cause me to re-dose or take ridiculous dosages and the WD's are hell and tolerance/dependence builds fast as fuck.
IV Cocaine- Only high-grade, bellringer shit and I always end up fucking my arms up, pin-cushion style if my funds are correct.
MDPV/Mephedrone ("bath salts")- On top of the fucking world ready to conquer it and fuck everything and anything, then you come down and are about ready to tie a noose and hang it up because of the crushing depression, paranoia, confusion, and overall sleep-deprived psychosis.
a-PVP- Same as above, but not nearly as euphoric + more paranoia IME
Methamphetamine- Can hook you like a fish without even realizing it as you loose track of how many days you've been awake. Depletes the fuck out of your DA and is neurotoxic due to excessive release of dopamine. You run out and wake up one day to find your madly depressed, can't focus on shit, and could sleep forever.
MXE or K- Just because euphoric dissociatives/ACH's are my DOC. IV S-Ket can be just as hedonistic as fucking IV coke due to potent DRI properties, even causes the bellringer.
Methadone + BZD's- Methadone is so warm, sedating, and cozy and the nod is heavenly with a BZD (e.g. my favorite with the 'done, diazepam/Valium). Methadone is the worst opioid kick and the longest kick I've ever had the hell of going through.
