If it weren't for the weed, I don't think I'd ever eat, my autistic ass just wouldn't think of it.
But also if all it takes is ripping open a packet and pouring stuff out to have ready to chew food (but not liquid or mush, the texture 😫), it's a winner. Because eventually I get to the point where I feel sick and NEED FOOD NOW or I'll throw up acid.
Brains are weird.
Consistently relying on weed to give you an appetite can make you dependent on it to feel hungry. Note how most heavy long term smokers you know are thin as rails.
If you happen to have this problem, however, a meal replacement drink like Soylent can be a godsend. It's pretty hard to eat a nutritious 2000 calories if you have to wait until you're really high at 9pm to start eating.
