johnnydoom 😵How was I the only one that knew? But, I did look it up, to be certain.
SP sales in Chicago was banned way back in '92, and upheld by the Supreme Court in '95. Legalization came up in 2018, but was tabled. I can find nothing that tells me it has been changed. It was due to graffiti. But, that hasn't stopped ever.
A lot of states &/or cities have such bans, or regulate sales to those over 18 or even 21. Some of those places even require the SP cans to be locked in, much the same as guns/ammo.
Every place, locally, I've bought 'canned air', I've had to show ID, for proof of age. And I don't live in Chicago, or even close. But SP is no problem here.
