Ice is one of the most - if not THE most - destructive drugs on the illicit market, in its physical effects, mental effects and behavioral effects. If someone you care about is abusing it, it is critically important to help them find effective help as soon as possible.
Ice is a strong stimulant, a highly purified form of methamphetamine that can be and usually is smoked. It causes a person to be energetic, artificially confident and euphoric. The ice user will normally stay up for days if the supply of ice holds out, eating little or no food. The high from ice can last a short time like a half an hour or as long as a full day. In most cases, the high from ice methamphetamine lasts much longer than the high from cocaine.
When the ice wears off, the person is likely to be exhausted, anxious and depressed. The cravings for more ice will be intense and will lead the person to do whatever it takes to get more ice and use it again.
An ice user can become violent and experience severe mood swings. If the person needs to commit crimes to get more drugs, he or she is likely to consider this more important than any other consideration. If the person is high while planning the crime, they are likely to approach it with great confidence and aggressiveness.
