Think about this for a second, and try to have an open mind about it.
Right now today, there are many drugs that drug users/dealers are not aware of, therefore they go on with their daily lives without it and spend time doing other things. Instead of focusing on something like Kratom, (we will use Kratom as our "random unpopular, unknown natural drug) they focus on the drugs that are glorified through our media, media that I remind you has BIG BIG money involved in it. Movies and music artists dont talk about Kratom, they talk about cocaine, ecstasy, crack, meth, heroin. Why do dealers sell these drugs? Because they are "valuable". Why are they valuable? Well because these are the famous drugs. Just like with people, fame = value. We don't choose what is promoted in TV and Music, but the people paying for the creation of this entertainment, they DO choose what is promoted. This is why the mainstream of rap music is entirely promoting bad things, not because their are so many bad people out there, but because thats what these record labels want to promote so they find artists that fit the bill.
I digress, now let's say tomorrow CNN and Fox News have a front page story that says "Kratom, the legal drug that needs to be Illegal because popularity with Youth". Do you think there is going to be less awareness about Kratom or more awareness? Well of course since these websites have millions of viewers, Kratom would surely have a new wave of interest. Does showing us school shootings on the TVs every week make school shootings a reduced occurrence? Hell no, it becomes more normal the more we see it. So stop glorifying drugs, gun violence and people use it less because they spend less time thinking about it.
You don't miss what you never had. Ignorance is bliss. Sadly we don't control what we are ignorant to, to some degree.
