I think my sister is on drugs? "aged" face?

wow meth or any drug can take you down. I had a friend that died from meth use and she looked like she was fifty two in her casket didnt even recognize her. She was only 36. This doesnt sound healthy so either she has health problems or she is most deff using drugs. Either way talk to her as a friend and see if you can get any answers drugs and alcahol really age people alot. watch her eating habits if you are around her drugs usually take your appetite away and you are less sociable as well good luck!
