  • Other colors of powder have been observed, such as brown, yellow-grey, orange, or pink.
  • Crystal meth comes in clear, chunky crystals (more or less clear depending on purity) that resemble ice.

Medicinal Use of Methamphetamine

Methamphetamine has very limited medicinal uses. These uses include treatment of narcolepsy, attention deficit disorder, and, for short-term use, obesity. However, these uses are very limited, and if meth is prescribed, a prescription is given that cannot be refilled.

How Methamphetamine Alters Consciousness

When an individual ingests meth by any method, they experience an intense euphoria, or rush, because the drug causes the brain to release dopamine rapidly.

Methamphetamine also can result in many of the same effects as other stimulants (ie- cocaine or other amphetamines), such as increased wakefulness, increased physical activity, decreased appetite, rapid heart rate, and increased blood pressure.



Psychological: Increased wakefulness, decreased appetite, intense euphoria,

irritability, insomnia, confusion, anxiety.

Physiological: Increased physical activity, increased respiration, rapid heart rate,

irregular heartbeat, increased blood pressure, hyperthermia.

Duration: Duration of short-term effects depends greatly on the amount of meth

taken and the purity of the drug. Most short-term effects occur almost immediately

after ingestion, depending on the method of ingestion, and last for many hours.


Psychological: Violent behavior, psychotic behavior, auditory hallucinations, mood

disturbances, delusions and paranoia, homocical or suicidal thoughts,

Physiological: Damage to the brain similar to stroke or epilepsy damage, damage

to blood vessels in the brain that can cause strokes, cardiovascular damage, tooth

decay, extreme weight loss (due to loss of appetite).

Duration: Brain damage caused by meth abuse can linger for months even after

the user stops methamphetamine use.


Psychological: Depression often occurs when the effects of meth wear off, which causes users to take the drug again and get addicted very quickly. This leads to a psychological dependence on the drug. Users also often use methamphetamine with friends, causing the drug to remind them of certain people, places, and events, which can cause psychological dependence to occur. Because of methamphetamine often being a social experience, the user may develop a habit of using it in certain situations or when with certain people.

Physical: Meth withdrawal can result in many negative physical symptoms, such as shaking, nausea, palpitations, sweating, hyperventilation, and increased appetite. Users seek more and more methamphetamine to get back to the state of pleasure it initially triggers or just to feel "normal" again. This results in physical dependence on the drug, and a never-ending cycle.

Meth Myths

1) Meth causes holes in the brain.

While meth often causes areas of the brain to become inactive or to have very low

levels of activity, it does not cause actual physical holes. This myth most likely started

because the inactive areas of the brain appear to be holes when displayed on a fMRI.

2) Meth is used primarily by white male bikers and truck drivers.

Meth use is extremely well-documented in these groups. However, high rates of use

have been seen in extremely diverse groups of people, not just the previously-

mentioned groups.
