What was the question on smoking cessation about nicotine replacement?

Very complex 4 options.

Four options were given and we had to mark the single best correct option. One of them was, varenicline comes with a black box warning of CVS side effects.

sir which is better option they asked

1- nicotine gums

2- varinicilin

dont remember other 2 options also not sure about 2nd option too

one is nictoine gum was applied before 15 minutes of eating something like that

and any caffeinated drinks should be avoided with it

Vareniciline comes with a black box warning

nicotine gums should not be taken 15 mins before caffeinated drinks or soda

One option was nicotine lozenges

Another option was Nicotine Gums vs Lozenges I guess

Like gums work faster than Lozenges or something like that
