When taken, crystal meth create a false sense of well-being and energy, and so a person will tend to push his body faster and further than it is meant to go. Thus, drug users can experience a severe “crash” or physical and mental breakdown after the effects of the drugs wear off.
Because continued use of the drug decreases natural feelings of hunger, users can experience extreme weight loss. Negative effects can also include disturbed sleep patterns, hyperactivity, nausea, delusions of power, increased aggressiveness and irritability.
Other serious effects can include insomnia, confusion, hallucinations, anxiety and paranoia.1 In some cases, use can cause convulsions that lead to death. Crystal meth is a highly toxic chemical that causes major disruptions in the physiological development of teens.
Long-range damage of Crystal Meth
In the long term, meth use can cause irreversible harm: increased heart rate and blood pressure; damaged blood vessels in the brain that can cause strokes or an irregular heartbeat that can, in turn, cause cardiovascular2 collapse or death; and liver, kidney and lung damage.
Users may suffer brain damage, including memory loss and an increasing inability to grasp abstract thoughts. Those who recover are usually subject to memory gaps and extreme mood swings.
