Opioids are compounds derived from opium which comes from the opium poppy Although in reality all poppies produce opoids the drug morphine codeine as well as other opioid pain killers are typically derived from opium A quick way to find or identify these compounds is to look for a six membered ring containing a nitrogen Often if you see a six membered ring with a nitrogen you have some sort of an opoid or a modified synthetic pain killer With that said morphine and codeine are typically not injected or given orally in pure form Instead their salts are used such as morphine sulfate or codeine phosphate Why are the salts used or administered instead of the pure substances or non salt forms I am not interested in drug names but to have you answer the why of this question 10 pt
