Marijuana usually doesn't lead to morhpine or heroin addiction. Also you don't get physically addicted to cannabis but rather mentally dependent if you use it regularly. Depression or fear can be caused by smoking too much but if you have someone watching out for you he could calm you down. You don't hallucinate after smoking marijuana. The closest you can get to hallucinating is with extreme doses you can get closed eye visuals or CEVs. Research better if you put out an article like that.
