Methamphetamineis commonly known as "speed," "meth," and "chalk." In its smoked form it is often referred to as "ice," "crystal," "crank," and "glass." Methamphetamine is a Schedule II stimulant, which means it has a high potential for abuse and is available only through a prescription that cannot be refilled. There are a few accepted medical reasons for its use, such as the treatment of narcolepsy, attention deficit disorder, and for short-term use-obesity; but these medical uses are limited.
It is a man-made stimulant and the bulk of methamphetamine currently on the streets has been illegally manufactured. The chemicals used in the manufacturing process can be corrosive, explosive, flammable, toxic, and, possibly, radioactive. For every pound of finished product, 5 or 6 pounds of chemical waste is left at the illicit lab site.
There are currently three types of methamphetamine:
L-methamphetamine (Levo-methamphetamine) raises the blood pressure and causes the heart to beat rapidly, but does not increase alertness very much. Shakes/tremors and stomach cramps are common physical side-effects.
D/L-methamphetamine (Dextro-levo methamphetamine) is made with the amalgam (P2P) method. It was popular during the 1960s, but it is still made and distributed. It has to be injected to get the desired rush and produces side effects such as shakes, tremors, and stomach cramps.
D-methamphetamine (Dextro-methamphetamine) is currently the most common. It is made by the ephedrine reduction process. It is 2 to 10 times as physiologically active as L-methamphetamine. It increases the heart rate, blood pressure, body temperature, and rate of breathing and dilates the pupils, and has fewer adverse side effects than the other two types of methamphetamine.
How long does Methamphetimines stay in urine?
Methamphetamine's high lasts anywhere from 8 to 24 hours, and 50 percent of the drug is removed from the body in 12 hours; ; it can be detected in the urine one hour after use and up to 72 hours after use.
How long does Methamphetimines stay in plasma?
Methamphetamine will stay in the plasma between 4 to 6 hours.
How long does it take for cat to get out of your system?
Cannabis:7-30 daysin urine, up to90 daysin hair, up to2 weeksin blood. Cocaine:3-4 daysin urine, up to90 daysin hair,1-2 daysin blood. Codeine:1 dayin urine, up to90 daysin hair, up to12 hoursin blood. Heroin:3-4 daysin urine, up to90 daysin hair, up to12 hoursin blood.
By this point, withdrawal symptoms will begin to occur, especially if the individual is a heavy, long-term user.Withdrawal symptoms from this drug are extremely unpleasant and come with intense cravings. This often motivates a user to take more and then more of the drug. The longer and heavier use is, the longer it takes to leave the system entirely. Typically, it takes 2-10 days for meth to be flushed out of the system entirely.
Blood concentrations of meth vary depending on the amount taken. Since meth can be prescribed by medical professionals, there is a therapeutic level of blood concentration, which usually ranges from .02-.05 mg/L. Recreational meth use, on the other hand, can range from anywhere between .01-2.5mg/L. Concentrations above .2mg/L are associated with abuse, and the threshold for toxicity for meth is above 2.5mg/L.
Meth levels reach peak blood concentration differently depending on mode of administration. The half-life of meth can range greatly, but for all methods of administration the half-life ranges between about 10 and 12 hours. When ingesting meth, peak concentration of methamphetamine occurs in approximately three hours. For smoking and snorting, peak concentration takes between two and three hours.
Methamphetamine withdrawal symptoms include:
- Increased appetite
- Anxiety and depression
- Muscle weakness
- Inability to feel pleasure (anhedonia)
- Anger and aggression
- Inability to concentrate
- Suicidal ideation
Meth users may think that doing methamphetamine can reverse some of the impairment effects of alcohol. That's because meth may restore alcohol-induced impairment in simple repetitive tasks of short duration.
However, NHTSA research has uncovered no restoration of alcohol-induced deficits of balance and steadiness. Overall, research indicates that methamphetamine is more likely to increase the impairing effects of alcohol.Methamphetamine Is Very Addictive:
Another reason that it is important to be aware of how long meth remains in your body is the fact that it is highly addictive. If you take more while some of the drug is still in your system you increase the risk of becoming dependent.
