Fall into canals; move in flocks between narrow city centre streets making a lot of noise; bike around with disregard to common traffic rules.

I'm not Dutch and I really enjoy going to Amsterdam, have friends living there, etc. From what I gather those are the main complaints, just annoyances and not really major problems.

Financing criminals when these same tourists go searching for other drugs, that's a real issue.

Disclaimer: I don't believe that weed is a gateway drug and I'm very pro decriminalisation of drugs and legalisation of recreational cannabis.

Sounds like you're describing the behavior of people who've had too much to drink. Alcohol is already legal.

Yes, but people can stay home and do that, they don't have to come to Amsterdam.

Be loud at all time of the day/night, litter, piss on walls/cars, etc.

> What exactly do you think stoned people do lol

There are many subsets of stoners, just like a guy drinking half a bottle of red wine at every dinner isn't the same type of alcoholic as the guy emptying a vodka bottle everyday by noon.

I used many drugs, with many people, some people are just trash, sober or drugged, drugs don't transform them into well behaved and civilised people

What kind of people travel hundreds of kilometers for a joint sand some titties behind a window ? ...
