I'm not totally certain if they were directly told or not but I think their guardians/ parents were told but did not find the evidence credible enough
yah they got told a full year in advance. she mentions that they were informed "last summer".
Drug addiction is real and its hard on the victim too. It's like cigarettes it can cause cancer but can't just be put down all at once. Otherwise it'd cause health problems and serious withdrawal symptoms.
Also the victims were not told about the drugged cookies so I'd be harder for them to stop eating them.
