Mentally =/= Physically. Trust me. They are WAY different.
You can get dependent on weed ..that's all. It's not like you're going to shoot someone if you can't get your weed.
Now let's take coke or heroin for example. Those are highly PHYSICALLY addicting ...and people will get mean and dangerous if they can't get their ****.
My best friend's teacher tried to make her go to rehab for marijuana. we LOLed.
I already mentioned something about rehab and weed on here before. Rehab is for real addictions. Going there cause you're 'addicted' to weed ...is really a waste of time and very pathetic to be completely honest.
Who are you to judge the worth of these addictions? Gambling can become a psychological addiction, so can smoking marijuana. Both of them have downsides, there's a possibility you could go bankrupt if you were a gambling addict, and there's a possibility that you could become a lazy bum stealing money from your loved ones if you were psychologically addicted to weed. Both of them have extremely negative consequences, so they are serious addictions.
Or, are you simply saying that psychological addiction doesn't exist? If so, then please show me some sources.
