Nothing about comparisons in there

Same issue as a lot of these things, they're trying to quantify overall harm:
The extent to which the drug activates the brain’s dopamine system How pleasurable people report the drug to be The degree to which the drug causes withdrawal symptoms How easily a person trying the drug will become hooked How much physical and cognitive harm the drug causes The street value of the drug
We know alcohol is cheap, readily available and has very nasty withdrawal. That's not in dispute, but it will inflate the overall score here because how addictive it actually is as a drug is just one factor of many. Look what it says for Heroin, for example:
his potent opiate has an alarming rate of addiction, with one in four individuals who try heroin becoming addicted
It'd be interesting to know the rate for alcohol

Basically a rip of the above, and written by this super scientific chap:
Jamie is a writer for several addiction and recovery publications. Jamie is in recovery himself. He particularly enjoys writing about his experiences with meditation, religion and holistic therapies.

Actually quite a decent article from a scan read, but it doesn't attempt to rank anything. Which is probably telling.

Eyyy, finally! This one is actually quite interesting and does highlight how relatively addictive alcohol can be, as they reckon some 20% (1/5) of people get addicted to it. Will put this to one side and read further as it actually looks interesting research.
Incidentally, in answer to your threads question: "The cumulative probability estimate of transition to dependence was 67.5% for nicotine users, 22.7% for alcohol users, 20.9% for cocaine users, and 8.9% for cannabis users."

Same stuff as before - no real detail etc.
