I have been a poly drug abuser since my first year in college 7 years.
I guess what appeals me was the fact mixing adds intensity to the drug effects, as well as reduce the side effects, while your tolerance is going up.
Whatever drug I could get my hands on, I would find a way to combine it. The first combinations was with opiates/stimulants. On my early day it was rx opiates with stims. Oxy/coke, morphine/coke, but later on I shooting speedballs heroin/coke, and heroin/crack.
There was my rave phase where I did MDMA/ketamine every weekend, while they was extremely hard.
Then came the trip wrecks, one instance I combined a high dose of soma, heroin, and amphetamine. I had thought the amphetamine would keep me up, but I ended up overdosing and ending up the ER.
Another phase I went through which lasted 6 months was doing a high dose amphetamine binge, then binging on benzos. I would take heroic doses of amphetamines, binge for a week, and when it was time to come down, I'd take high doses on benzos. I guess after many weeks, and six months my mind has finally had enough with the constant abuse and went ape****. I ended up spending 2 weeks in a mental hospital for suicide attempt after a long binge. This was two years ago, and I usually don't combine hard drugs anyone, let along take hard drugs.
Then there is the weed/benzo. Weed itself make me anxious and paranoid, and benzos along are boring, but mixing them does the trick for me.
