I know how to find them and craft the inhaler charges and I have several drugs to increase charge, but I keep thinking I'm automatically using them, but I am fairly certain I have everyone I have ever built or bought. Plus, sometimes it takes a full minute in combat for me to be able to use it again, even though I have 127 inhaler charges. Also not sure that the consumables are working either, but those I don't see as many of so they probably are.
I'm playing on Xbox one and I'm pressing the down button on the directional pad, what else would I need to do? TIA
