Which medi-kits? This is probably intended, as eg. some items use painkiller only as plot device (crack, smokes), instead giving a boost to the user only. Some use Stimulant as their effect is primarly stimulating (mutant meat, apple). But better safe than sorry.
@Legionof1: to be sure, check live capture and iterrogations, also what gets recovered from 2x2 units. These issues were always tricky and I'm afraid the new system might've broken them.
