Feeling relaxed or detached from surroundings. Hallucinations , which can affect any of the senses — visual, auditory, etc. Increased intensity of emotions and sensations. Mood swings 5. Spiritual experiences.
Synesthesia, or a mix-up of senses, such as hearing colors or seeing sounds. Temporary psychosis. Drug use often precipitates the development of tolerance, where the brain becomes desensitized to the effects of the drug. This leads to the person requiring more of the drug to attain the desired effects.
There is some evidence that hallucinogens, such as peyote, can produce tolerance 2. Another phenomenon, known as cross-tolerance, occurs with many hallucinogenic drugs 2. Peyote also has a strong effect on the body, similar to other hallucinogenic drugs. These physical effects may include 1,2,4 :. Dilated pupils. Dry mouth. Flushed skin. Increase in body temperature, which can lead to excessive sweating. Increased energy levels. Increase heart rate. Increased blood pressure.
Muscle weakness. Impaired motor skills and coordination. Loss of appetite. The phosphorus assists in the second step, by consuming iodine to form phosphorus triiodide which decomposes in water to phosphorous acid , regenerating hydrogen iodide. The reaction can also create toxic, flammable white phosphorus waste. The conceptually similar Emde route involves reduction of ephedrine to chloroephedrine using thionyl chloride SOCl 2 , followed by catalytic hydrogenation.
The catalysts for this reaction are palladium or platinum. The Birch reduction , also called the "Nazi method", became popular in the mid-to-late s and comprised the bulk of methamphetamine production in Michigan in The reaction is allowed to stand until the ammonia evaporates. It has been the most popular method in Midwestern states of the U. In recent years, a simplified "Shake 'n Bake" one-pot synthesis has become more popular. The method is suitable for such small batches that pseudoephedrine restrictions are less effective, it uses chemicals that are easier to obtain though no less dangerous than traditional methods , and it is so easy to carry out that some addicts have made the drug while driving.
Hydrogen chloride gas produced by a reaction of salt with sulfuric acid is then used to recover crystals for purification. The container needs to be "burped" periodically to prevent failure under accumulating pressure, as exposure of the lithium to the air can spark a flash fire.
Short-term exposure to high concentrations of chemical vapors that exist in black-market methamphetamine laboratories can cause severe health problems and death. Methamphetamine cooks, their families, and first responders are at high risk of experiencing acute health effects from chemical exposure, including lung damage and chemical burns to the body. In Japan, methamphetamine seizures are usually white crystals of high purity, but contain impurities that vary according to the means of production, and are sometimes adulterated. Diagnostic impurities are the naphthalenes 1-benzyl-methylnaphthalene and 1,3-dimethylphenylnaphthalene,  arising in the Nagai and Leuckart routes, and cis- or trans- 1,2-dimethylphenylaziridine, ephedrine, or erythro-3,4-dimethyl- 5-phenyloxazolidine, arising in the Nagai and Emde routes; these are absent in the reductive amination route.
A common adulterant is dimethyl sulfone , a solvent and cosmetic base without known effect on the nervous system; other adulterants include dimethylamphetamine HCl, ephedrine HCl, sodium thiosulfate , sodium chloride , sodium glutamate , and a mixture of caffeine with sodium benzoate. In the United States, illicit methamphetamine comes in a variety of forms with prices varying widely over time. Impurities may result in a brownish or tan color. Colorful flavored pills containing methamphetamine and caffeine are known as ya ba Thai for "crazy medicine". An impure form of methamphetamine is sold as a crumbly brown or off-white rock, commonly referred to as "peanut butter crank".
Another popular method is to combine methamphetamine with other stimulant substances , such as caffeine or cathine , into a pill known as a "Kamikaze", which can be particularly dangerous due to the synergistic effects of multiple stimulants. Reports in of the appearance of flavored " Strawberry Quik meth " circulated in the media and local law enforcement,  but were debunked in by the DEA, although meth of varying colors has been seized.

This study has provided the first objective data regarding the use of potentially abusive drugs by tractor-trailer drivers Prescription stimulants, such as amphetamine, methamphetamine, and phentermine were found in 5 percent of the  drivers [who participated in the study], often in combination with similar but less potent stimulants, such as phenylpropanolamine. Nonprescription stimulants were detected in 12 percent of the drivers, about half of whom gave no medical explanation for their presence One limitation of these findings is that 12 percent of the randomly selected drivers refused to participate in the study or provided insufficient urine and blood for testing; the distribution of drugs among these 42 drivers is unknown Finally, the results apply to tractor-trailer drivers operating on a major east-west interstate route in Tennessee.
