I think freedom of information has a lot to do with this. These days you can chat with people around the world about drugs and find out the truth about them from actual users. We see that people using DMT are generally very intelligent people, not social outcasts detrimental to society as the government propaganda would like you to believe. Because of the internet, people can visit sites like this one and see for themselves what users of DMT actually are like.

In the past, royalty used psychedelics. The rulers of the Aztecs, Mayans, etc., all used psychedelics. They were commonly used by the upper class and were considered sacred. This partially changed (was moved underground) when the Spanish invaded and demonized psychedelic use because it wasn’t part of their catholic religious belief system. Over the years though, psychedelics have made their way back into the church despite their efforts, and now there are quite a few catholic churches that use ayahuasca.
It's only a matter of time that psychedelics are viewed as sacred again, rather than detrimental drugs.
