What you seem to be confused over is how poorly we talk about addiction.

Alcohol and Benzos can kill you, so when people talk about physical dependence, they usually mean them. I feel like this is often used to obfuscate the fact that because ____ can't kill you it must not be addictive.

Then there is psychological addiction: Anything that makes you "feel good" and "want more" falls in this category.

So amphetamine, weed, sweets, and coffee, for example are generally cited as addictive because they are easy rushes to feeling good irrespective of their harm.

Where cannabis gets deserved flack is that proponents are downplaying the harm and addictiveness by comparing it to "chewing your nails"

Here is a very good source that illustrates the benefits and harms of medical cannabis.

More like, alcohol dependence? It provides a profound mental effect that is easy to become an addiction perhaps, so different from blowing bubbles.

This is pretty obvious, and it takes a certain strained logic to ignore it. I suspect folks who over-react to the suggestion that strong chemicals can become a detrimental habit, have perhaps some vested interest in believing it.
