Weed is physically addictive. Withdrawal is very mild and only lasts a few days but it can happen with heavy use.

I didn’t experience it until I got into edibles and vaping concentrates and I had used weed regularly off and on for twenty years at that point.

So it takes heavy use, but physical withdrawal is a real thing with weed. But as I said, it’s the only drug I’ve been addicted to I would cold turkey.
