// Would put each of the variables into an object
var myVariables={};

// giving values to variables (you can do this through whatever means you were intending)
myVariables['varAlcohol']="some value";
myVariables['varMarijuana']="some other value";
myVariables['varElse']="some else other value"

// Look for a change to the array of variables
$(myVariables).change(function(){
  var isZero=true;
// By itterating over each value in the array and setting isZero false for nonzero instances, you can be sure that the only situation in which isZero will be true is if all are zero
  myVariables.forEach(function(myVariable){
    if($(myVariable).val()!="0"){
      isZero=false;
    }
  });
  if(isZero==true){
    $('#crafft').hide("fast");
  }
});
