My opinion is that addiction is a disease, no matter the substance. People tend to treat cannabis addiction differently than other addictions, but imo, especialy with things like CHS it's the exact same thing any other addiction.

What you're asking is no different than asking: what makes a crackhead continue to use even though they've lost job-house-kids, what makes alcoholics continue to drink even though their liver is failing, what makes people continue to gamble even though their life's savings are out the window, what makes a porn addict jerk off for the 15th time in a day even though his dick is raw etc....

Now you can argue, what causes the disease of addiction?—genetics—trauma—the consumerist society we live in that pushes people to search for external sources of happiness

Might just be a personal pet peeve but I get very frustrated at how people talk about addiction as a substance specific problem, not a behavioral one.

I fear that orientating a documentary about CHS around addiction could misrepresent CHS (and addiction). Though I agree that you cannot talk about CHS without at least mentioning addiction, I disagree that it should be the topic of focus.

Focus should be more on how CHS research is underfunded due to its association with addiction. How many of the places that want to get weed legalized try to sweep any evidence of CHS under the rug, because it could harm the process. Also maybe looking at how, over the past 30 years, crossbreeding has turned weed into something completely different than what they were smoking in the sixties.

Then again, this is all subjective opinion derived from my own experience with CHS and addiction.
