The first time I smoked I felt the same: nothing good. But eventually I got hooked. You become addicted and feel terrible while not on it. Once you're on it, you're good to go for a while again. (I eventually managed to quit.)

I only tried smoking when drunk and the effect was to make me dizzy, like I’d been spinning on a roundabout too fast.

That effect is normal the first time(s) you smoke. It goes away eventually. The alcohol probably made it worse, or more uncomfortable. Either way, good on you for not starting. I succeeded with not starting various times, but did fail eventually. Growing up with a mother who smoked (did quit too though) who's also my main parent did not help.

I tried smoking when drunk, the effect is I feel more alert and less dizzy.

I've done many drugs in past:

Marijuana, cocaine, heroine, vaping, estasy and did it like a month with friends but i don't feel any addiction.

I did feel some effect but never felt addicted.

But i am addicted to peanut butter, the i don't have atleast one spoon i feel very bad whole day.

So, a serious question. Do you need to do something for longer duration (more than a month?) to get addicted to these drugs?

It's because I have been putting nicotine in your peanut butter.
