Why not? I for one would never do them but who I am to stop others from trying them?
We’ve factored God out of our picture, a God that warned us that demons are not physical things.
Well, you are who you are. If you have reason to try and stop people from using them, then do so. If you have reason to encourage people to use them then do so.
However, state and local governments have reason to make them illegal, because they do have profound negative effects on the users and their communities.
If such entities put it up to a vote of us citizens to make them illegal or legal, I’d vote to continue to make them illegal.
That is just my opinion. I am a former drug addict who has used cocaine in the past, and my main addiction was to pills, but I have not used meth, heroin or crack, although I have known people who have. I don’t believe that there is any redeeming value to these drugs at all.
