Not sure I’d agree with any study saying it is physically addictive, habitually I’d agree. So you’re willing to ignore science… that’s sounds like a river in Egypt to me mate.
Habit forming and addictive mean the same thing in medical terms. Cannabis has observed withdrawal symptoms like sleeplessness, appetite changes, and nausea that classify it as physically addictive. You’re ignoring these because it dosen’t suit your narrative and beliefs.
My point on the sugar though is it certainly does create addiction. I agree with this provided your talking about refined sugars. The point is though it’s not a drug. Sugars are a natural part of the human diet. They literally make up your DNA. Refined sugars are not natural though.
