Dutch Coalition Supports Use of Drug Detection Spray in Schools
A majority of the Dutch parliament now supports the use in school of a special spray developed in Israel which can detect traces of marijuana, ecstasy, heroin and cocaine. The idea is to spray it on clothing, lockers and other student material. When the test is positive the school would inform the parents.
The opposition parties D66 and SP are critical of the plan and actually support the testing of ecstasy at raves to guarantee a pure product. This proposal was not supported by the coalition.
Here is the Dutch article.
The article doesn't mention what the spray is called. I found this online.
I think it's the responsibility of the parents to use this spray, not of the government and schools.
Say goodbye to our free country.
