hi dear @josevas217
It is sad to think that at some point slavery was legal, I believe that the people of our country, although if they have freedom for certain things, they suffer financial slavery, people earn between 10 and 40 dollars a month, that is financial slavery and it happens today.

Nevertheless this last one is legalized in almost all the countries of the world, but the marijuana not

I think the world is becoming aware of this issue, as with gay marriage, people have realized that they are things that do not affect anyone, and in the USA in some states it has been legalized, which indicates that in the future will be legalized in more countries
