Granted I haven't explored all the options yet, if these don't exist yet I can't see why they wouldn't considering we have derms and medpacks from your consumer grade up to mil-spec within the game.
The idea behind it would be simple, a syringe that you can inject someone with that would sedate them. You can use it in @trusted situations or in more 'creative' situations (i.e. - already unconscious or grappled) It would open up some more creative ideas for roleplay and add some value to the game I think.
Just my 2 Chy.
