One thing is personal possesion...

Another thing is trafic of drugs...

The first is allowed in some european countries.

The second, NO(except well known exceptions).

It´s a danger to the public health, and the state can´t make propaganda about the drugs, because unlike in your country, the health is PUBLIC.

I don´t care if someone wants to smoke until his dead, I care if this someone tries to sell my son the drug.

Respect, and you will be respected.
