Is the worldwide consumption of coffee at a point that should something happen to coffee production, there would be severe global HEALTH problems?

Basically, since coffee is drunk as much as 1/3rd of normal tap water and is the 2nd most traded product in the world, I'm wondering whether what problems would happen globally if the global production of coffee met with some disaster?

Ignoring economic problems, I'm interested in the health problems that might happen to a large global population.

Coffee has a fairly minimal nutritional profile so a sudden break in the worldwide supply of coffee would have little to no impact on world wide nutrition; no one is going to starve nor suffer any deficiencies.

Caffeine is moderately addictive/habituating but withdrawal is fairly short lived typically with minor to modest effects. A fair number of will people with marked addictions will likely be kinda irritable and maybe have some headaches or problems getting to sleep for about 2 days (possibly up to about 1 week); rarely some people report nausea or anxiety issues too.
