Why is beta-carotene dangerous for smokers?

I like to use codeine occaisionally (once or twice a week at most) to help me relax and feel a minor high. Typically, I'll take about 90 to 150mg per session (100 to 200mg per week on average). Sometimes I take Tylenol-3's, and sometimes I extract the codeine from these pills and drink it pure. What are the potential health side-effects of this usage, both short- and long-term?

Thanks!

Do any alcohols have any specific benefits? As in, is tequila better than vodka? And is red wine the best choice because of its antioxidants?

My granddad has been an alcoholic for ages — way before I was born. I am really worried about my granddad’s drinking. My father doesn't like me to see him when he is drunk, but that is kind of hard. What are the best groups for alcoholics? And most importantly, what should I do?

I really want to try pot because I am SICK of being uptight and careful all the time. I have been depressed and anxious for several years and I just want to feel SOMETHING different. But I've had a couple of panic attacks (both related to medication) and they were the most frightening things I've ever experienced. I'm scared that pot would do the same thing to me. What do you think? I know you can't encourage me to smoke pot but I would very much appreciate an honest answer, which I know you always give. (I know that smoking pot is not the best thing to do when you have depression and anxiety, but it would only be once, and I would be with friends. By the way, I'm not currently on medication as I find it useless. But I'm not trying to self-medicate. I just want to remember what it's like to experience an emotion that is not depression or anxiety). Thank you very much.

1) I have had acid coming up my throat from my stomach for the last 3 weeks. It comes up and just burns my throat. What is it? Do I have an ulcer? By the way, I get 3 hours of sleep a night, and my roommate doesn't help the situation.

2) I have recently asked you about my would be ulcer. I shall pose the question again. Lately I have this damn acid coming up my throat. I've been under a lot of stress and have strange sleeping habits. I am also drinking a lot of coffee. I drink about 5 cups of coffee a day and my roommate isn't exactly stress relieving. I go to bed about 3:30am and wake up about 5:45am for crew. Am I dying? Do I have an ulcer? What's wrong with me?

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???

My girlfriend of about a year is going to college next year as am I but we are going to attend different colleges. We are about forty-five minutes apart in distance and we have no problem whatsoever in keeping the relationship and we plan on keeping it alive and healthy, but I have a problem with alcohol. I don't drink alcohol and don't ever plan on it but I am curious as to it being rude or improper to ask her not to? Is it my place at all to ask her that she not drink at college? I feel strongly about her in this situation. She doesn't drink but thinks she might like it... Is it fair or my place to ask her not to drink? Thanks, Alice...

My friends take Pepcid AC when they drink to reduce the redness on their faces. Is this safe? I'm worried that it will hurt their stomach linings. Please help.

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?
