We have, at this point, over a 100 years of evidence showing that prohibition of psychoactive substances (alcohol, cannabis, cocaine, etc) doesn't actually do much to reduce consumption but do create an immense amount of suffering not just for anyone participating in the trade or consumption of those substances, but also anyone remotely connected to them - cf the immense violence perpetrated by drug cartels in the Americas, mostly because people living in the US seem to be in denial about their appetite for drugs.
So please, stop banning things you don't like, tax and regulate them instead. Use the tax proceeds to fund "social media rehab" clinics if you'd like.
Draconian "I don't like it, it gets banned" government wasn't a good idea in 15th century Spain, it's still not a good idea now. Let your fellow citizens make bad decisions, just ensure that the government is poised to profit from them.
