I agree with you that you can not paint a broad picture of all marijuana users. That is why i used my friends as examples to prove the misconception wrong. As for being addictive, if marijuana really is physically addictive (which we don't know due to a lack of research), its effects have to be less than alcohol and probally tobacco as well. I do not buy into psychological addictions. Anything think can be psychological addictive, that has to do with the user not the drug by psychological i meant withdrawl can lead to depression, mild scizophrenia, etc. (vs other physical withdrawl symptoms like shaking, headaches or chest pains) and the example of your friends doesn't prove the misconception wrong. It just provides one possible outcome of it's use. There are many many people who do become your classic stoner/dropouts, thus that stereotype isn't actually a misconception (though thinking EVERYONE turns out that way is)
