I'm thinking of taking another pilgrimage this summer, this one to Mexico City. The biggest problem is Mexico's draconian antivape laws. You can't bring it into the country at all. A few places, mostly at tourist locales, may (as of right now) sell vapes, but of unknown quality, and there's hardly anywhere, except private homes where smoking or
vaping is legal. I cannot discover if lozenges are legal, but it seems patches and gum are. I find patches to be worthless--might as well slap on a piece of duct tape, just as effective and much cheaper.
