Ice is the translucent crystal, smokable form of methamphetamine.
It is also commonly called glass or crystal and, like other stimulants, is highly addictive. The use of ice results in a longer, more intense high and an enhanced and more rapid onset of the negative effects of other forms of methamphetamine. Similar in appearance to rock candy or rock salt, ice is sold in clear, heat sealed cellophane packets. If your teenager is using ice, he or she may experience increased alertness, euphoria, appetite loss, dilated pupils, elevated heart rate, increased respiration, and elevated body temperature. Prolonged use can cause blurred vision, dizziness, loss of coordination, collapse and toxic psychosis.
