A-PVP and A-PHP are both insanely addictive. Was given a 3.5g of A-PVP as a senior in high school not knowing just how insidious that stuff was. Spent all of my last year in high school tweaking off of that shit. They both provided a far more euphoric rush than Meth, especially when I vaped them. The short duration and highly euphoric rush makes them more akin to crack cocaine than methamphetamine. I haven't touched them in a little over 10 years and I still crave them regularly, have dreams where I'm using them, and I get phantom smells throughout my days where I'll randomly smell it as if I had taken a bump then and there. I've never done crack but I've done damn near everything else in terms of street drugs and RC's; A-PVP and A-PHP are by far the most addictive things that I have ever put in my body
