alt Hacker NewsThe reason we don't need tight regulations on bleach is because we don't have a societal issue causing people to drink it and hurt themselves..
I think you missed out on a long time period of 4chan. They managed to get a number of people to mix ammonia and bleach.
More people do this accidentally trying to clean something than have ever done it because 4chan told them to. Still, the incidence rate is low.
