Methamphetamine
Some of the deadly effects of meth include:
- Permanent damage to blood vessels of the heart and brain
- Heart attacks or strokes due to high blood pressure
- Malnutrition from weight loss
- Severe tooth decay
- Disorientation, confusion
- Liver, kidney, and lung damage
- Destruction of tissues in the nose (if sniffed)
- Infectious diseases and abscesses (if injected)
- Psychosis
- Depression
- Damage to the brain, stroke, and epilepsy
Because meth creates a false sense of well-being and energy, someone who uses meth will typically push their body beyond its limits. This causes the user to have a severe “crash” or a physical or mental breakdown when not taking the drug. Therefore, tolerance to the drug builds over time, and the user, in order to avoid unpleasant withdrawal symptoms, is kept in a vicious cycle of abusing the drug to avoid these side effects. Because meth is extremely addictive, it is best to seek treatment immediately, even if the user has just started to use the drug. The sooner one seeks treatment, the better chance they have of preventing any detrimental damage to their body and health.
