> As a Dutch resident, I have never understood why so many (mostly American) tourists visit The Netherlands just to use drugs in Amsterdam

If it was legal in their home country we wouldn't have drug tourism. Amsterdam would be just any other European city. It's the allure of being able to consume cannabis in a cafe that is simply irresistible, and a privilege.

As a non-Netherlands resident, I think the city takes it for granted that cannabis is legal-but-regulated and we shouldn't be so judgemental of tourists who otherwise have to obtain cannabis from the sometimes murky criminal underworld, and risk getting arrested or being sold low-quality weed, or worse: risk getting contaminated weed laced with synthetic opioids.
