I need some societal ills/threats that nowadays are being treated as mostly neglected, but in a near future one could imagine a proper moral panic and attempts to eradicate it (regulate, properly supervise, keep away from minors, etc.) for common good. The threats would have to be more or less real (at least conflicting studies).
Imagine, that with enthusiasm similar to war on drugs one would try to fight with junk food. After all technically speaking such food is clearly harmful, just one may feel a bit weird with prisons filled with people who were caught while selling fried bacon.
OK, so what are possible targets of future moral panics of threats that are already present nowadays (so no nanomachines):
-junk food (salt, simple sugars, saturated fat) - damn unhealthy
-peanuts (some people have life threatening allergies to that)
-artificial fertilizers (an material for making explosives)
-drones (seem to have huge potential for terrorism /assassination, that’s something that I’d actually expect to be heavily regulated sooner or later in RL)
-computer games/internet (addiction potential)
Do I miss some more threats with moral panic potential?
A perfect answer would include a list of minor but real risks that has some scientific reasons, that nowadays are not being taken too seriously as public threat that requires proper crusade. In case of any cultural ambiguity threats should apply especially to the Western civilization.
