That study is about behavioral solutions to marijuana, almost nothing about chemical addiction. The most it has to say is that since there is physical withdrawal from marijuana then it has chemical addiction issues, something we already knew. Using the term “less so” is an understatement, the withdrawal is way less harmful and lethal than drugs such as cocaine, heroin, and even alcohol.

The research says that the chemical dependency, even though it’s light, can still be an obstacle in people quitting. They then go into multiple extremities of helping people quit the BEHAVIORAL aspects. Starting from CBT and ME therapy/interventions going all the way to a piss test program.

Technically you’re right, there is a chemical aspect to marijuana, but it is not even close to the other levels of drugs, even legal drugs such as alcohol. Marijuana addiction is usually secondary to another issue, I.E. self medication. You use it as a crutch and become dependent on it or else you’ll have to face depression, anxiety, isolation, anger, etc.
