alcohol is very different from operating a commercial vehicle a couple
days
after you smoked a joint.

It may be unfair that one can not partake in getting high when one has
several days to recover. You have any reasonable way to accomodate the
casual user and still weed out the chronic users?

In the end, most professional pilots accept that they can't partake. It's a
compromise and flying is full of compromises.
