Some drugs are genuinely dangerous. Many are addictive and will damage the quality of one's life, even if buying and using the drug isn't illegal. Normalizing addiction to drugs as a regular, normal, accepted part of everyday life is not the answer.
Keeping them illegal does not "protect" anyone and just creates more crime, death, and misery. You've swallowed the propaganda -- it was never about protecting people, it was designed for oppression and it's wildly successful at that.
Take a look at any video of police busting people for drugs: does it look like they're trying to help those poor innocent victims or are they gleefully enjoying their ability to completely fuck with those people in the name of "protecting" them?
The fact that drugs are still such a problem despite countless billions of dollars shows that it's never going to work in the way that they promise.
Drug addiction is a health issue, not a crime. My brother died of a heroin overdose and the law did not help him and the fact that the only resources public money went to were jails and prisons vs clinics shows where the priorities lie.
