The source is this guy. I have no idea if this is a reputable claim or not, but Israel has lost all right to the benefit of the doubt. I have neither proof nor doubt that they're doing this. Here's another guy on Twitter:

I was expecting it to be in powder form, mixed with the flour. Don't get me wrong, I'd only eat food from a zionist if I were starving, but I'm not convinced. Maybe they were trying to smuggle drugs for some dealers. Zionists are already causing chaos with mercenaries near Rafah. I doubt those pills were meant for the average Palestinian to find inside the flour, recognize them as a particular brand of opioid medication and say "I guess I'll get high to numb the pain" then proceed to take them while baking bread.

Why is it unlikely? Israel has been purposely maiming Palestinians for decades and since recently in record numbers. To me it seems like just another way to make life in Gaza unbearable and even more challenging than before to make sure that there’s lots of highly addictive drugs in the market. It’d result in many deaths and people having to care for their addicted family members or friends.

We are talking about two different things here. I said it was probably a case of smuggling, someone (not a dealer) got the wrong bag of flour.

Poisoning Palestinians through tainted food is not an unlikely scenario but If they are doing it this wouldn't be a proper method. I already stated why and I don't want to go in depth about it as it is sensible information.
