Long story short..
My sister has been shooting up morphine,opana, and other opiates. I don't know if she has ever shot up heroin.
She does have a legit medical condition and is pain.
She has told my mom that she stopped shooting up instantly. I really doubt this but my mom seems to believe her.
She won't let anyone count her pills as well which is high suspicious. Her last morphine script she went through 90 pills in a little over a week.
So, is it really possible to stop shooting up in a day? Keep in mind she has a script to morphine so she isn't going cold turkey (if she did stop shooting it up).
