Yaba
Profile
Yaba, the Thai word for "crazy medicine," is a tablet form of
methamphetamine, a powerful stimulant. These synthetically produced pills
contain 25 to 35 mg of methamphetamine and 45 to 65 mg of caffeine. Tablets are
available in a variety of flavors (including grape, orange, and vanilla) and
colors (most commonly reddish-orange or green). Various logos (commonly "WY" or
"R") adorn yaba tablets, which are the size of the end of a drinking straw. Yaba
looks and tastes so much like candy that many young users (often including
ecstasy users) underestimate its harmfulness. Methamphetamine is also available
in powder ("crystal") form, which can be processed into a rock ("ice") or liquid
form.
History
Methamphetamine was derived from amphetamine in Japan in 1919. Both of these
chemicals were originally used in nasal decongestants and bronchial inhalers.
Methamphetamine has also been used in the treatment of obesity.
During World War
II, military in the United States, Great Britain, Germany, and Japan used
methamphetamines to fight fatigue and enhance performance. After the war, when
military methamphetamine supplies became available to the public, abuse of
intravenous methamphetamine became an epidemic in Japan. During the 1950s in the
United States, methamphetamine tablets were legally manufactured, and used nonmedically by students, truck drivers, and athletes. In 1970, the Controlled
Substance Act restricted the use of methamphetamine and made it a Schedule II
substance. Since yaba contains methamphetamine, it is also illegal.
Today, the United Wa State Army, the largest drug trafficking organization in
Burma, is the primary manufacturer of yaba in Southeast Asia; Thailand is the
primary market for these tablets. Yaba is a recent phenomenon in the United
States, although it has been popular in Southeast and East Asia for some time.
Methamphetamine tablets are sent primarily by mail to northern California and
the Los Angeles area, and although the demand for yaba appears to be primarily
in Asian communities, popularity is increasing among rave attendees.
Methods of Use
The most common method of using yaba is oral ingestion. Tablets can also be
crushed into a powder and either snorted or mixed with a liquid and injected. In
addition, tablets can be heated on aluminum foil to produce a vapor. The vapor
is then inhaled.
Effects
Yaba is a powerful central nervous system stimulant with longer lasting
effects than those of cocaine. This is because cocaine is metabolized in the
body more quickly than methamphetamine. Effects produced by yaba will be
dependent on the dose taken. Some effects include:
- Euphoria
- Insomnia
- Irritability and aggression
- Decreased appetite and nausea
- Hot flashes, dry mouth, and sweating
- Damage to the small blood vessels in the brain
- Increased alertness, wakefulness, and physical activity
- Increased heart rate, blood pressure, respiration, and body temperature
Effects of chronic abuse include:
- Tremors
- Hypertension
- Hallucinations
- Psychotic episodes
- Paranoid delusions
- Violent behavior
- Hyperthermia and convulsions
- Agitation, anxiety, and nervousness
- Mental confusion and memory loss
- Psychosis similar to schizophrenia (characterized by paranoia, picking
at the skin, self absorption, and visual and auditory hallucinations)
Addiction/Tolerance/Withdrawal
Methamphetamine in all forms is very dangerous and has a high potential for
abuse and dependence. Moderate to chronic use of yaba and other methamphetamines
may lead to physical and psychological dependence, and even death. Abuse is
characterized by consuming increasingly higher dosages during a period of 3 to
10 days with no sleep, in an attempt to maintain the initial high. However, no
amount of the drug can achieve this effect so users may become frustrated,
unpredictable, and violent. When an individual goes through withdrawal from high
doses of yaba, as well as all other forms of methamphetamine, severe depression
often results.
