I would like to make a Dilaudid nasal spray but I'm not sure how much 8mg Dilaudid and water should be mixed for it to be effective... Now I got the nasal spray bottle of "Salinex" which includes sodium chloride, purfified water, glycerin, and benzalkonium chloride... Should some of that be mixed in with it? I have no clue lol I also have 4 8mg Dilaudids to make this so please someone give me the right measurements to make this spray and make it the most effective I can
