<human>: Can you give me a shortened version of the text?

I know Reddit is very anti slut shaming/pro slut acceptance so i apologise if i offend anyone, but this is really bothering me.

My sister doesn't work or go to college, she has no ambition and she leeches off our parents. She spends all her money getting drunk at the weekend and will often not come home so i suspect she is sleeping around with all these different guys. She has guys who will pick her up from home late at night and then drop her back an hour later and it's clear she is getting used for sex but she doesn't seem to care. 

It's horrible to say but i feel embarrased when friends visit, she wears see through leggings and very low cut tops. I saw on her phone she has sent dirty pics to guys and i don't want every guy to only see her as a piece of meat. She has also tried cocaine.

I worry if this carries on she will end up being one of those young single moms who people look down on and that all the good guys will stay away from her. If i talk to her about this i don't know how she would react. I think it would be better coming from my mom but my mom doesn't think there's any problem. Is this a phase or is it too late for my sister to change?
<bot>: My sister spends all her money on alcohol and sleeps around with different guys who don't care about her. I want her to change before it's too late. I would like advice on how to handle this.
