Police start searching his bags for marijuana but come up with nothing.
An officer in a beanie then tells Sousley he'll be handed a citation if any marijuana is found.
The patient then speaks up, explaining he only takes THC pills to help with his pain relief.
"You'd never say you'd do anything to save your life?" Sousley asks the officer.
"Marijuana's saving your life?" the officer responds.
A doctor soon enters the room to explain the situation, but police turn around and say they have the right to search despite not having a warrant.
One officer then re-searches the patient's bag, making Sousley agitated telling police they've already searched it.
"I'm not giving you a thing – just write me a ticket for marijuana," Sousley says.
Officers then ask to search the bag behind him which carries all his required medication.
"It's a bag of my medication – I'm not letting them dig through it," he explains.
"It has my final day things in there and nobody's going to dig in it."
The doctor soon requested Sousley to stop recording as the argument began to escalate with the patient asking to go home.
Sousley told Bolivar Herald-Free Press a security guard at the hospital called the police after witnessing him smoke a cigar in the parking lot.
He added he was heavily medicated during the police search.
Sousley's video has been viewed more than 650,000 times with many comments accusing police of "harassing a dying man".
"The cops must be really bored if they're coming to a call about marijuana," another said.
