I can't say about France. But in Switzerland, there is a "three strikes" system where if you are caught with drug, the first time you have a $100 fine; Then a higher fine, called "Day-fine" which is proportional to your income; Then maybe, just maybe, a jail sentence.

Comparing that to the US, where if you get caught dealing marijuana, you get a 5 years minimum sentence. That seems disproportionate to me. Maybe police in the US is more compassionate than some militants make it seem, and that's why they don't like catching people for that kind of crime?

Looking at Wikipedia[1] it appears the number of policemen per people is two times higher in the US than Switzerland, and about the same as France. If it is true that "the police are plentiful and they come down fast" in Switzerland (which I would not agree with), it is twice as true in the US.
