answer:I did some googling and found nothing to prove that theory. Also judging from my own personal experience and those around me, I’ve never met anyone including myself who doesn’t want to eat more while they’re high. Literally probably the number one thing associated with weed and it’s effects is the munchies. For good reason. You say that might happen with daily enthusiasts over a long period of time. I’ve been a daily enthusiast for several years, and have not had that experience, but maybe if you mean much longer term like 10–20 years of daily use, that could be right. But I have no idea, have never heard that, and can’t find much on the web to back that up.
