You know how nicotine has a similar shape to Ach so can bind to the Ach recepetors on the post synaptic membrane of the post synaptic knob(neurone), it's less rapidly broken down by Ach-ase right, but what does it actually do? Just transmits an action potential like normal? Why is that bad? I mean how is what nicotine does different from Ach just binding to the Ach receptors?

    if it is less rapidly broken down then it is active for longer, therefore it increases the activity, therefore it acts as a stimulant in low doses but in high doses it kills you. Nicotine is one of the strongest plant poisons.

    There are issues which becoming dependent on nicotine. Generally people are not down on nicotine use, only on getting nicotine through burning tobacco leaves. Besides nicotine burning releases a lot of other substances which are inhaled and can cause lung cancer. Actually a lot of burnt sustances do this. So refrain from setting fire to it and most people won't know or care what you do. You can buy nicotine gum in pharmacies.
