The government should just accept the fact that the drugs can't be eliminated. As long as the demand exists, the people will find a way to secure them. The only viable option is to legalize and regulate them.
Making it legalize and regulate them would really cause to much more trouble on this world and its not really right to exclude it and I would rather choose to stick on prohibiting it rather than on legalizing it because i cant imagine a society on which drugs are legal.
Then you are living in a lie manufactured by government and repeated by sheep called society.
Do you honestly think that legalization of drugs would suddenly create more addicts? On the contrary.
There were times when you could buy all kinds of poison, completely legal in your local drug store (late 19th century) but I didn't hear about causes of mass poisoning.
People are not so stupid as government and authorities are trying to tell us. War vs. drugs is one big lie, it is something to sink tax money into, nothing more.
