Nicotine is as addictive as heroin. Doubt you get physically ill trying to kick porn.

Physical addiction to nicotine is hard to establish and quite weak. It is strongly psychologically addictive.

I'm cautious about the new addictions, and I think there's some misunderstanding in sensationalising in pop therapy, but I can see how porn addiction or sex addiction can happen.

It's pretty well established that people can be addicted to gambling, and I don't see much difference between that and other non-substance based addictions. Gambling is more well known because it is so well tuned to exploit the addict.

Very true; when I finally quit smoking after a decade of being a heavy smoker I have found that it only took a me few days to get through the physical addiction but it took me months to get over my psychological addiction (e.g. not think of smoking after eating). Adjusting my behaviour was really the hard part and it required a lot of willpower.

Same here. The first 3 days were bad, but nothing special. But now, after almost a year, I'm still fighting with the desire to smoke.

In combination with external factors (like stress) I can totally see why people are returning to addiction again and again.
