Benzos are way more addictive than most people think they are. Its about as addictive as cocaine for most people. Most people don't get euphoria from benzos, but some people do. If you get euphoria from them, it's about as addictive as heroin, sometimes even more depending on the person. The actual addictiveness isn't even the worst part though, it's the withdrawals. Addictiveness is basically how fast you get addicted to it, but the withdrawals from quitting are worse with some drug classes than others if you were just as addicted to one as the other. Benzo withdrawal is the #1 worst out of all the common drug classes. Even if you just used Xanax for a week, the withdrawal would be worse than using cocaine for a month. Be careful with benzos, if you did 27 mg in your first week and only quit because of a drug test you're almost certain to develop a significant addiction if you get back into it. Stick to either just using it on special occasions, like big parties, or just not at all. Best of luck
