1) I found a white powder in my friend's car and I think it might be cocaine. I'm not sure if it is or not. I don't know if I should confront him with it or what I should do. I don't want to see my friend get hurt, but if I'm wrong, I don't want to falsely accuse him of something like this. How should I go about handling the situation?

2) I am a first-year business student and have a little sister who is a junior. I think she is doing cocaine because I found some "paraphernalia" in her room last week. What can I do without damaging my relationship with her?

Recently (the last six months or so) I've been getting really tired after a couple of drinks (let's say three or four). By eleven at night, I'm ready to call it quits. My friends and boyfriend poke fun at me because I usually head home before they do. How can I last longer in a healthy way? I definitely try to drink water throughout the night, but is there anything else?

Is there a natural way to get high?

What can I say to prevent someone from drunk driving?

My friend recently told me that she has a serious blow problem. She lives with her boyfriend and she said that all they do is work, sleep, and blow. By telling me this I understand that she has taken some very important steps into wanting to get better, but I'm completely useless in trying to help because I just don't know enough about the drug and rehab and ways to support her.

So far I've made the suggestion that she come spend some time with me and away from home so that the reminder of it is lessened, I can prevent her from bringing it in, and can try and keep her occupied to take her mind off it. What else can you suggest?
