I actually disagree on that one. Joy should allow you to be happy regardless of the situation, but if you have a weaker strain of the disease, the symptom may not be as apparent. And you can have the symptom without having the disease.

The thing about joy is that you can have it even when you're sad. Happiness is circumstantial. Joy is forever. And of course, side effects can take effect outside of the medicine.
