From what I'm hearing from Southern U.S. Law enforcement buddies, they're seeing a lot of unusual activity on the mexican border. Some people wanted to leave or enter over the last month, so the flow of people alone has been unusual in both directions on top of angsty cartel guys trying to find new gaps in a less-active border patrol. Add in the fact that Chinese-made precursor chemicals necessary for the drug trade have dried up, on top of that a less-mobile populace to overall traffic the end product and shortages are quite possible.
When economies tank drug addiction and suicides go up. If you count alcoholism as a drug addiction it's a no brainer, but people get creative. Look at the Russians and krokodil, or locally we've got dirty shake n bake meth.
I've never been too fearful of the virus. I'm much more afraid of social and civic instability in a populace that is one paycheck away from feeling morally obligated to crack down every front door and beat the owner over the head because they see anyone 'better off' than they are as having become an enemy of the people. People are dumb, panic-ridden animals, and it really doesn't take much to flip the ones on the....less-civilised end of the scale? I worked with lots of people in the poverty zone, and I can tell you from personal experience, I want to make sure they're stocked with doritos, weed, cigarrettes, whatever the hell they want, because we're only 9 days of withdrawals away from having a living zombie army on our hands. Hell, without power, water, internet, etc. even normal everyday working people can get nutty. Groups are scary when those inside feel less personal responsibility for their actions. Imagine whole blocks coming together out of mutual anger and heading towards those who still do have power and smokes.
So hopefully people will manage a bit better after the restrictions lift. I think we all could've been fine if people were actually sober enough to use masks and wash their hands, not eat sandwiches in the public bathroom, etc. and pay attention to not catching funky sicknesses.
