they really are just as addictive as heroin, or as addictive as opiates in any form. i only say this because ive been around the recovery scene a couple times. and the two absolute life stealing drugs every time are benzos and opiates. the two worst class of drugs ever created. and i speak from experience. not only have i witnessed many people detoxing from benzos, but many of the patients that come into my pharmacy are addicts also. imagine jus because you take xanax for a month strait , you may not sleep for 5 weeks. i cant stress it enough man. once or twice is not gonna kill ya but if you dont know what its like and you havnt already done em, then dont. your not really missing anything. and you could be one of the unlucky ones that a few months after you start taking em, when you dont take em you cant eat cant sleep, nausia, cold sweats, restless leg syndrome , seizures.....and when i say cant sleep , i mean racing thoughts, nightmares, and a general feeling of wanting to kill your self. seriously i know about ten people in the past 3 or 4 years that have died due to adding shit like xanax to taking something like percocet or even alcohol. just be careful.
