I want to thank you and Columbia for this wonderful service! I have been browsing your archives for some help, here is the situation: I want to know what I can do to support my significant other when he is released from Drug Rehabilitation. Please help me!

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?

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?

(1) I have a daughter who just joined AA. She has a drinking problem. What are our responsibilities to her as a husband, father, mother?

(2) Should any alcohol be kept in her house or our house (we are the parents) when she is around?

(3) It has been said that alcoholism runs in families — is this true? Does it seem to skip generations? If so, why?

A couple of questions for you: what are the long-term side effects of one abusing prescription painkillers, such as Vicodin? What advice can you give to someone who has gotten off of them to help them stay off???

What is "gaming addiction"? Is it a real thing? I can play some games, like World of Warcraft or League of Legends, for a whole day, and I've sunk 150+ hours into RPGs. How many hours in front of a screen are too many?

I'm a college student who is struggling with the decision on when to see a doctor for treatment with my depression symptoms. I believe that I need to get treated for depression, but I'm just as scared about not getting treatment as I am about starting antidepressant drugs in my current lifestyle. As far as I can tell, I'm exhibiting the classic symptoms of depression, and have been for a while — frequent crying fits, days where I lose all motivation, and sometimes, even thoughts of suicide. But I drink frequently, almost every weekend, and use marijuana occasionally, and I am quite unsettled by the possible interactions between antidepressants and these other substances. In my day to day life I do very well — I hold a good GPA, have good relationships and a good social life, function well most of the time, and stay in shape for sports. I don't intend to change my lifestyle significantly to make room for depression treatment. But when do I need to get help? I don't want to force an unnecessary change on myself, but I don't want to put myself in danger from depression, or even worse, from the drug interactions between antidepressants and alcohol or weed. What is the tipping point?
