Are Go-Juice addicts impossible to recruit?

[Mr. Blues]

Whenever I get raided by one of these bastards they just never seem to get downed. Whether I seal them out and let the elements do the work or send an army of children to pummel them with their bare fists, they always end up dead and never downed.

Since Go-Juice essentially stops them from feeling pain, does that mean they can never be downed without getting killed? Is pain the only factor that determines whether a pawn goes down or not? Can't they lose consciousness due to blood loss or something?

psychic shock lance will work.

If you have the skip psycast and get the following situation 
1. the go-juice pawn is fleeing because the raiding party has been broken 
2. the go-juice pawn's movement speed has been reduced at least somewhat 
3. the go-juice pawn is bleeding fairly quickly (at least 100%/day) 

then you can consistently get them via blood loss, but it'll take a lot of time/micro. You have to keep skipping them away from the edge of the map until they pass out from blood loss (which bypasses the storyteller's "death on down" mechanic for some reason, unlike someone being downed by pain)
