What you say is true in general, but there are execeptions: for example, the Republicans judge the harm done by heroin, fentanyl, amphetamine and cocaine to be very high -- probably higher than the average estimate of the harm as judged by the Democrats. Ditto street crime.

My understanding (without data, sorry) is that the conservative position blames drug addiction on bad choices and evil, rather than circumstances. As well the focus is on authoritarian policing as opposed to “harm reduction”.

These are generalities, sure
