Weed is no “addictive”, but it can be habit forming. Addiction is very specific and we don’t typically use it correctly in day day speech. You won’t have physical withdrawal symptoms like opioid, alcohol, or caffeine.

I would love see a study on lo g term effects. We won’t due to ethics. So far every study is either users have no long term side effects but it can make existing problems worse, or weed makes you try hard drugs and we should all know that is not real.
