It is 100% valid. I suggest you do some research before making uninformed statements.

Other countries have been trying different approaches with varied success, but all have had better results than our system.
Be so honest to mention that all drugs except cannabis are illegal in the Netherlands.
EDIT:
The only reason why there have been done heroin experiments is because some addicts where not able to stop. The whole issue is that when an addicts has somewhere in his /hers mind made up that they are never going to stop, they are not going to stop. And that is how the dutch recover program functions. Let the person become aware of their problem. Because that person can only stop using drugs when he or she decides to do so. The point is to make people think what they are doing and that they keep a log of the every day life. Every time they have a set back, get up and think and try again.
If people finally decided to stop using drugs and solve the addiction, the mantra is to not give up. Get up on your feet again and start thinking where did you go wrong.
Keep track of your actions, where did you go, who did you meet, what did you think of, how did you feel. Hidden in all those questions the addicted people will find the trigger. And once they know the trigger, the next step is to prevent that trigger. An example is some addicts who stopped using and cleaned themselves up, felt back because in their neighborhood there where too many triggers to say no. It takes an intelligent approach to prevent people from using or to help people from their addiction. Just legalizing or criminalizing is both not the answer.
When legalizing all drugs, you create a social time bomb. Knowing how man functions and knowing the social structure, some sort of relieve must always be present. And the best way is to use the not addictive onces. Alcohol and cannabis are as history has shown to be the best way.
Particularly in the U.S., there is still widespread support for criminalization approaches and even support for the most extreme and destructive aspects of the "War on Drugs," but, for a variety of reasons, the debate over drug policy has become far more open than ever before. Portugal's success with decriminalization is highly instructive, particularly since the impetus for it was their collective recognition in the 1990s that criminalization was failing to address -- and was almost certainly exacerbating -- their exploding, poverty-driven drug crisis. As a consensus in that country now recognizes, decriminalization is what enabled them to manage drug-related problems far more effectively than ever before, and the nightmare scenarios warned of by decriminalization opponents have, quite plainly, never materialized.
I have been mentioning the bolded text long before. No work is drug use. When a large part of humanity has nothing to do or no hope, they start to go insane or give up on life.
If it was not for the EU and all those EU loans and gifts : No work.
