Any addictive drugs that slow movement later in life?

Hard to say: Stephiebelleiz, your question isn't very clear. Are you asking if you now have muscle slowing and you used to use opiates or certain tranquilizers? If so, there's probably no correlation. I will say that people who used crack Cocaine or methamphetamine may have permanent brain changes. Sounds like you need to talk to a doctor face-to-face rather than online. Good luck.
