I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality. - MLK
Also, we need to legalize recreational drugs and prostitution.
OK, I understand your perspective but really, no more so than alcohol. If you have a predilection for addiction (that rhymes) then you can become entrapped. However, it is just a psychological addiction and not a physical addiction.
Are any of these a good idea? No, they aren't. In my view of how these could be legalized, they all (including tobacco and alcohol) would be sold in a very boring state store, where you would be warned of their potential harm each time you made a purchase and your quantities would be limited and tracked to discourage your reselling them. I'm shocked that alcohol is advertised and promoted the way it is.
The way it is now, crack, meth, dope etc. are glamorized by their illegality. Look at the damage this causes. This isn't working and yet we persist.
