Did PTSD have an effect on the british populace after world war one?

After watching peaky blinders last night it left me to wondering what effect did PTSD have on the people returning from the war to home?

As a side question, was there an increase in crime due to the trained killers all coming back?

Follow up question: in Peaky Blinders they also make a point to show the veterans using various drugs like opium and cocaine. How common was drug use in the returning vets and how was it seen by the general public?
