Crystal meth is an extremely addicting drug, and has been known as one of the most dangerous street drugs due to its tendency to induce violent behaviour and its long-lasting effects.
Signs of crystal meth use vary from person to person, depending upon body mass, route of administration, and dosage. The general effects experienced are euphoria, anxiety, hyperactivity, and insomnia.
When larger doses are taken, one may behave violently, go into a state of confusion, and in some cases have a heart attack or stroke.
One common sign that someone might be using meth is an onset of fidgety, obsessive behaviour, similar to those who suffer from obsessive compulsive disorder. Along with the fidgety behaviour, one is uncharacteristically talkative, to the point that they may be incoherently rambling.
If a person suddenly seems hyperactive and obsessive, it may be an indication they are experimenting with methamphetamine.Physical symptoms of methamphetamine use include red eyes, dilated pupils, and sweating. Methamphetamine users often dart their eyes around not being able to concentrate on any one thing for very long.
Meth addicts commonly have many scabs and skin lesions, as they pick nervously at their own body, and the substance slows healing and deteriorates the immune system. Finally, meth almost always inhibits hunger in the user. Crystal meth addicts often lose weight at an alarmingly fast rate, and are unhealthily thin.
