Since we were both a bit nervous to try it (maybe partly because we both went to school with a girl who had developed a serious heroin problem) we just sprinkled some on top of a bowl of weed. Don't remember the taste but it definitely tasted different than weed and like I said, it mostly just gave me a heady, numb high. But yeah, if we'd gotten a proper dose, we probably would have both wound up passing out opium den style.
During my drinking days, one of the coworkers I hung out with liked to #### around with younger women who were really into pills and they really added to my negative feelings about opiates/opioids. They acted like ####ing fiends over it and looked way older than they were (that shit really causes you to age rapidly- something people don't realize or focus on enough). So yeah, maybe you took some stupid risks stealing vikes from your family but like you said, you should mostly just be glad you never got hooked.
