I can guarantee you, it is no different than what 42nd Street used to be 10 years ago. BTW, drugs are illegal in Holland. The laws are just not enforced in Amsterdam. You will be surprised, how many of those laying on the streets all drugged up are just tourists from the US and England. Even then, Amsterdam has a much lower crime rate than any big city in the US.
Lack of enforcement is the same as being legal, as far as the effect.
And I don't care if the people drugged out on the streets are Americans, Spanish, Dutch, or Chinese. They are there because no one enforces the law...which is the same as it being legal.
If you legalize drugs here, we will get the refuse from other countries who want to smoke dope and shoot up without penalty.
Your position is without merit and is based on the pipe dreams of one who has not very much life experience.
