I have done "ice" a few times. It's not something you can get around here anymore so you have to go out of town to get it. I have smoked it, snorted it, and put some in a drink and drank it. I have never tried crystal meth so I don't know how to compare it to that but to me it is a lot like coke except I don't get quite as "high" off it, I can think a lot clearer on it than coke and I can have serious conversations with people without losing my train of thought. I can act sober on it as well, unless I have been up for days which is usually the case when doing it because it also does last MUCH longer then doing some coke. It makes me want to do lots of stuff as well like I could go non-stop, a lot of people like to work on it. The only downsides I don't like is the staying up for days cause a little goes a long way and if you smoke it, which is supposedly what it's made for, then it's real hard on your lungs and you will be coughing up gross stuff for a few days after. I also have a REALLY hard time eating on it and I have to force food down with a drink cause I can't even swallow it. I really have only done it maybe 4 times in my life but thought I would share my experiences.
