addicted. Meth is used through injection‚ smoked‚ ingested‚ or snorted. The drug stimulates the central nervous system‚ because of a dramatic dopamine increase. Dopamine is directly related to the pleasure functions in the brain‚ which relate to reward and motivation. Due to large amounts of dopamine‚ the high from meth makes positive feelings such as a sense of wellbeing‚ increased confidence‚ and alertness/wakefulness. Meth is known to have similar effects as cocaine does‚ however meth acts on the

The Meth Epidemic The origin of methamphetamine in the U.S. started on the west coast in the state of Oregon. This is a man-made drug that is easily “cooked” in kitchens across the U. S. Pseudoephedrine is the main chemical ingredient in the drug and also the key component of cold remedies such as Sudafed. The Pseudoephedrine is combined with other chemicals readily available in gas‚ rubbing alcohol‚ or drain cleaners. The effects of the drug are of a distinct deteriorating effect. Some people

“David Parnell used to drink meth‚ his drug of choice‚ dissolved in orange juice as he drove down the road. He also took meth with his coffee or ate it‚ wrapped in toilet paper. "I don’t want the pictures to send someone into craving‚" he said. Parnell shot himself in the face with an assault rifle in 2003. The police who took the crime scene photos initially assumed he would probably die. The blast of the gun blew off the tip of his tongue‚ split it in two and broke most of the bones in his face

Meth Mouth Meth mouth is severe decay and loss of your teeth. Tooth fractures and acid erosion can also occur. Meth mouth occurs when someone has had an extended period of time using methamphetamine. Meth mouth is caused by the side effects of the drug and also lifestyle choices. Side effects of meth include clenching‚ grinding the teeth‚ and dry mouth. If someone who uses meth has poor oral hygiene and drinks a lot of sugary drinks‚ their teeth are usually worse than meth users who have good

Optical Properties of Quasicrystals: Negative Refraction Quasicrystals‚ or crystals that display the unusual property of non-periodicity (while remaining ordered)‚ were discovered in the 1980s by Dan Shechtman. A highly controversial topic‚ Shechtman did not produce a paper describing them for over two years after their discovery. However‚ within the past 30 years‚ the scientific community has come to accept them‚ reproduce them for study‚ and even award Dan Shechtman with a Nobel Prize for their

reactions are often contaminated with impurities. One method for purifying chemicals‚ recrystallization‚ takes advantage of the differences in the solubilities of the desired products and the impurities and the tendency for the slow formation of crystals to exclude impurities from the crystalline solid.

During the synthesis of acetaminophen‚ it is necessary to dissolve all solid material‚ and heat the reaction at a high enough temperature and for a long enough time period to ensure completion. Cooling the mixture in an ice bath ensures that all crystals have formed‚ and drying removes any remaining solvent. The synthesis of acetaminophen does not result in a pure product‚ so recrystallization is necessary to purify the substance. During recrystallization‚ it is important to dissolve all

Because chemists always want to get the chemicals they get as pure as possible. And a good way to purify chemicals is to make crystals of them. When they are in solutions you can have all sort of impunities but when they form crystals the crystals contain much purer compounds than in the solution and the impurities are left in the solution. generally the crystal is a very precise arrangement of molecules all the same fitting together like pieces and some sort of construction toy ‚the impurity
