I'm here to suggest that they're a little boring as-is. You either have countermeasures that work one hundred percent of the time, or you don't. And getting those countermeasures requires some doing and often a puppet, which for players expecting to deal with them often means just not going outside and getting into trouble until you can get a staffer to help you out.
It'd be neat if there were ways to mitigate (but never totally ignore) the effects without those countermeasures. Things like high endurance, drugs, or cyberware could allow you to eat one and not take the full effect, but still be deafened and hit with worse debuffs than that adds now. I'm talking big stamina hits, bleeding ears, drunk-walking, that kinda stuff. So that they're still a threat without the main countermeasure but it's not such a binary situation.
This'd make them more generally useful (as of now I can guess pretty accurately whether it's worth popping one or not, and if I guess correctly I will always always win) and allow people to make a decision about whether to spring for countermeasures or try to skip them and mitigate the potential damage otherwise. Anyway there's my idea.
