My brother owns a convenience store and recently called me to tell me about an incident he encountered. He sells hot hands hand warmers even in the summer which is not that unusual because he has several patrons that work in cold storage facilities and use them year round.
He had a customer come in recently and ask for some hot hands. My brother proceeded to ask him which cold storage facility he worked at, he replied none. He said he used the hot hands to pass a drug test. He pours clean urine in a bottle and then puts the hot hands against the bottle and tapes it to his leg. By doing this, he is able to keep the urine warm. He went on to say he’s used this method multiple times to thwart a drug test (by the way- he does not test at First Choice!). He even said that on occasion the temperature became too hot and scalded his leg.
