Benzodiazepines can be physically addictive to any mammal on the planet made to consume them long enough, whether they love or hate the drug class itself does not matter. Actually, if memory serves benzodiazepines are the second most addicting (I still say Opiates are first) drug class on the planet. There is nothing I can think of that compares to the physical/emotional/spiritual agony somebody with a real Opiate addiction goes through during detox--besides tales of Hell, that is. But that said, absolutely the most dangerous class of drugs to come off are Benzodiazepines, which does strike me as odd, considering it's so hard to overdose solely on benzodiazepines, yet take them long enough and then stop and you risk serious seizures, even death.
The problem with benzos, much like opiates, lies entirely in how insidious the addiction is. For starters, people who do not suffer from anxiety, insomnia or even depression have very, very little chance of becoming addicted to benzos--unless they are recovering alcoholics or opiate addicts, but even then I feel the chances are fairly low.
In my experience the three main groups at risk of serious benzo addiction are:
1) Opiate Junkies: There is no better opiate potentiator to be had. Benzos kick your Opiates into the next level.
2) People suffering from extreme Panic Attacks and Anxiety Disorders, also Insomnia. Benzos are the only medicine guaranteed to work every single time. That's the problem. They work too well. And what starts out as a tool becomes a crutch, becomes a wheelcheair, becomes an electric scooter.
3) People who use benzos to avoid their comedowns after abusing stimulants, and to calm their psychedelic journeys, that wind up developing an affinity for one of the World's greatest "Chill Pills".
