ā€œEither tonight or tomorrow, Iā€™ll be dead.ā€

Those are just some of the final words of a Nova Scotia man who filmed a moving message warning others not to smoke as he lay dying in a hospital bed hooked up to machines.

On Monday, John Wiseman gasped his last breaths after a two-week stay in hospital. The 65-year-old man from New Minas, N.S. died from complications of smoking, according to his family.

ā€œIn his last few days, he discovered that he had an ulcer in his stomach that was bleeding,ā€ Wisemanā€™s sister Sandra Wiseman-Burrell told CTV Atlantic on Friday. ā€œThey tried to do a couple surgeries on it, but the doctor had told us that his bowels, his small bowel was like mush, and they couldnā€™t even sew into it anymore.ā€

Wiseman-Burrell said her brotherā€™s heart and lungs were also failing and he suffered from emphysema for some time.

ā€œThey couldnā€™t do anything more,ā€ she said.

In an effort to discourage others from meeting a similar fate, from his hospital bed sharing his painful health experiences.

ā€œI wish to hell nobody else starts smoking. You see all this stuff here. Itā€™s all thatā€™s keeping me alive right now,ā€ Wiseman said. ā€œI hope that anybody sees this, will remember what itā€™s like and will not start smoking.ā€

Wisemanā€™s sister said the video was important to him.

ā€œIf it just touched one personā€™s life, he would be happy that somebody stopped smoking or didnā€™t start smoking, but his message was ā€˜Please, donā€™t smoke. Youā€™ll end up like me,ā€™ā€ she said.

Since Wiseman-Burrell uploaded the video to Facebook on Thursday, it has attracted more than 4,600 views. She echoed her brotherā€™s message with an emotional plea of her own.

ā€œDo whatever you have to do, but just quit smoking because your family doesnā€™t want to see you, like I saw my brother,ā€ she said as her voice cracked.
