Off topic , but swim had this part caught his attention while looking up opiates :
"Before an addict can inject heroin, it must be made into a solution. To dissolve the heroin, the addict mixes heroin in a large spoon with water. Lemon juice is sometimes added to help dissolve the heroin. The solution or cocktail is heated until it boils and is then drawn into a hypodermic needle."
