Would it not be possible/appropriate to use (borrowing heavily from
Alistair Miles' earlier example):

@prefix skos: <http://www.w3.org/2004/02/skos/core#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix mesh: <http://www.nlm.nig.gov/mesh/schema#> .
@prefix md: <http://www.nlm.nig.gov/mesh/descriptors#> .
@prefix mq: <http://www.nlm.nig.gov/mesh/qualifiers#> .

mesh:descriptor a rdf:Class;
	rdfs:subClassOf skos:Concept;

mesh:qualifier a rdf:Class;
	rdfs:subClassOf skos:Concept;

md:economics a skos:Concept;
	rdf:type mesh:descriptor;
	rdf:type mesh:qualifier;

mq:"adverse effects" a skos:Concept;
	rdf:type mesh:qualifier;

or possibly:

md:economics a mesh:descriptor;
	rdf:type mesh:qualifier;

mq:"adverse effects" a mesh:qualifier;
