We had opium dens in the past, why not fentanyl dens today?

It's just something to do to fill the boredom.

(That's to say: Just because something was mildly bad in the past doesn't mean that the current, somewhat similar, thing in the present isn't horrifically bad. The issues are orthogonal +- 5deg max)

If we kept opium dens there probably wouldn’t be widespread fentanyl use, isn’t it a reaction to the challenges of getting less dangerous opiates, i.e. is more potent and easier to smuggle?

Many places have “supervised consumption” sites or decriminalization now that has gone very poorly, I think in retrospect having opium dens for those who choose to live that way might have been a better alternative to the current state.

My comment wasn't really about drug consumption and policy, that was just a metaphor...
