I smoke hookah on occasion, but am not a regular hookah smoker. Recently some of my friends have expressed interest in smoking hookah but are concerned about the health side effects; needless to say, for very legitimate reasons. However, non-tobacco shisha, made simply of herbs and molasses, claims to be a healthier alternative to regular shisha that contains tobacco. Though I can assume it is not without its shortcomings, is it still healthier then regular tobacco products, as it claims?

I recently had a very bad experience with alcohol poisoning where I blacked out for several hours and had a horrible hangover the next day. Many of my friends told me that when they had blacked out or even just gotten sick from alcohol, they did not want to drink again for weeks or months. One friend even stopped drinking altogether from such an experience. I am worried, though, because it is only one week after my terrifying experience and I am already craving alcohol again. Why hasn't my horrible experience turned me off to alcohol, while the day after, I swore I would never drink again because it had been sooo scary? I cannot be an alcoholic, because I only started drinking two months ago. What is wrong with me?

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'm curious about drugs — in particular what happens when you chemically combine methamphetamine and PCP and how it might affect the body. Some places online say they're the same thing, but I'm not so sure.

My uncle shoots heroin. My father used to do cocaine. My moms' (both of them) used to smoke weed with their friends when I was eight. I smoked weed when I was twelve. I sold weed at 14.

I don't want to continue in the vein of my addictive family (no pun intended). How hereditary is addiction? What measures can I take to avoid falling into the same hazy trap of my family members?

I know all the effects smoking has on the body, but nobody seems to have information on what it does to your sex life. What are the effects, like dryness, de-sensitivity in areas, etc? If I quit, would sex be better?

I am a freshman on a collegiate varsity sports team. Team gatherings, when we are not practicing, usually consist of excessive drinking with and without drinking games. I did not drink in high school and when I tried drinking with the team it made me feel really sick. I want to bond with my teammates (they are really great when not drunk) but I don't know how because if I am the only guy in the room not drinking I can't play drinking games with them, discuss favorite types of alcohol, or even carry on a real conversation because at a certain point in the night they stop forming coherent sentences. I need to be friends with this group of people but I would like to do so in a way that allows me to remember the night in the morning. Is this possible? What should I do?

While I don't really approve of their lifestyle (why devote six days a week to practice only to reduce your performance with alcohol?), I make no moral judgement. I don't want to change their way of doing things, I just want them to respect my way.
