A few years ago, the thought occurred to me that a lot of christians are overweight, and I came up with hypothesis: since many indulgences are considered by many as forbidden, the remaining indulgence of food might tend to be overused. I focused on alcohol, since many christians (especially in the south) think it's sinful to drink alcohol. I looked up maps of alcohol use and maps of obesity. I didn't do the work to combine them, but looking at the maps side-by-side, it appears my hypothesis may be correct: https://www.evernote.com/shard/s5/sh/18dbb20c-29bb-412d-8d5d....

My hypothesis for pot would be the same - pot smokers may be less tempted to eat food all the time since they're getting their kicks from pot.
