How can you help your spouse or partner cut the bad habits out of his life,like smoking, drinking alcohol and other more ?

Maybe can encourage him with something interesting or motivation. Talk to him but not all guys will listen. My hubby is a heavy smoker when i know him and he used to smoke few pack everytime i met him during our dating days but because there's some encouragement and motivation in his life he choose to cut down his smoking by having some other activities and others alternative in life and eventually as time past he success quitting his bad habits but he did suffer a little when he trying to quit smoking . After all everything is worth it as time past 😆
