The shops in La Latina are rather odd, many with second hand and period pieces, reflecting the fact that there is a major Rastro (Flea market) in all the streets on Sundays. Despite its name this one is a clothing and bric a brac shop :)
I don't partake (never was a smoker of anything) but I do approve of the legalization and now there are a few extra whiffs here and there in public, but otherwise no noticeable "problem"... they are finally treating us like adults in Ontario, serving alcohol in grocery and corner stores as they have long done in much more socially advanced places like Quebec ;)
