Meth addicts are the worst. Heroin addicts are peaceful while they are under the influence. Meth addicts are up all night and they hit the streets while people like me are going to work and they are actively dangerouse.
It’s when they are coming down that the violence escalates.
I worked right next to a guy in a cubicle at an old call center job back in the 90s. Right next to him, every day. Until the day he wasn't there and I learned later he went to rehab for heroin. I had no idea that they guy I worked productively next to every day and engaged in conversation was a junkie.
