Drug symptoms; Paranoia, agitation and even extreme anger. Some insomnia. Delusional thoughts. Later on skin irritations. They surface as hard bumps. If you pick at the bump it turns into a sore that doesn't seem to want to heal. Something in the center. If picked it lasts months. They hurt and make a scar once dissipated. If the bump is left alone eventually they go, but it takes a very long time. Possibly makes the eyesight blurry. Deep depression. The skin also itches when those bumps surface.
