Methamphetamine is a powerful, highly addictive Crystal meth taking that affects the central nervous system. Crystal methamphetamine is a form of the drug that looks like glass fragments or shiny, bluish-white rocks. It is chemically similar to amphetamine, a drug used to treat attention-deficit hyperactivity disorder ADHD and narcolepsy, a sleep disorder. Because the "high" from the drug both starts and fades quickly, people often take repeated doses in a "binge and crash" pattern.
In some cases, people take methamphetamine in a form of binging known as a "run," giving up food and sleep while continuing to take the drug every few hours for up to several days. Methamphetamine increases the amount of the natural chemical dopamine in the brain. Dopamine is involved in body movement, motivation, and reinforcement of rewarding behaviors. Taking even small amounts of methamphetamine can result in many of the same health effects as those of other stimulants, such as cocaine or amphetamines. These include:.
Currently, most methamphetamine in the United States is produced by transactional criminal organizations TCOs in Mexico. This methamphetamine is highly pure, potent, and low in price. The drug can be easily made in small clandestine laboratories, with relatively inexpensive over-the-counter ingredients such as pseudoephedrine, a common ingredient in cold medications. To curb this kind of production, the law requires pharmacies and other retail stores to keep a purchase record of products containing pseudoephedrine, and take steps to limit sales.
Methamphetamine production also involves a of other very dangerous chemicals. Toxic effects from these chemicals can remain in the environment long after the lab has been shut down, causing a wide range of health problems for people living in the area. These chemicals can also result in deadly lab explosions and house fires. People who inject methamphetamine are at increased risk of Crystal meth taking infectious diseases such as HIV and hepatitis B and C.
These diseases are transmitted through contact with blood or other bodily fluids that can remain on drug equipment. Methamphetamine use can also alter judgment and decision-making leading to risky behaviors, such as unprotected sex, which also increases risk for infection.
Studies indicate that HIV causes more injury to nerve cells and more cognitive problems in people who use methamphetamine than it does in people who have HIV and don't use the drug. In addition, continued methamphetamine use causes changes in the brain's dopamine system that are associated with reduced coordination and impaired verbal learning. In studies of people who used methamphetamine over the long term, severe changes also affected areas of the brain involved with emotion and memory.
Although some of these brain changes may reverse after being off the drug for a year or more, other changes may not recover even after a long period of time. Researchers don't yet know whether people breathing in secondhand methamphetamine smoke can get high or have other health effects.
What they do know is that people can test positive for methamphetamine after exposure to secondhand smoke. Yes, a person can overdose on methamphetamine. An overdose occurs when the person uses too much of a drug and has a toxic reaction that in serious, harmful symptoms or death. Inabout 15 percent of all drug overdose deaths involved the methamphetamine category, and 50 percent of those deaths also involved an opioid, with half of those cases related to the synthetic opioid fentanyl. It is important to note that cheap, dangerous synthetic opioids are sometimes added to street methamphetamine without the user knowing.
Because methamphetamine overdose often le to a stroke, heart attack, or organ problems, first responders and emergency room doctors try to treat the overdose by treating these conditions, with the intent of:. Yes, methamphetamine is highly addictive. When people stop taking it, withdrawal symptoms can include:. While research is underway, there are currently no government-approved medications to treat methamphetamine addiction. The good news is that methamphetamine misuse can be prevented and addiction to the drug can be treated with behavioral therapies.
The most effective treatments for methamphetamine addiction so far are behavioral therapies, such as:. Research also continues toward development of medicines and other new treatments for methamphetamine use, including vaccines, and noninvasive stimulation of the brain using magnetic fields. People can and do recover from methamphetamine addiction if they have ready access to effective treatments that address the multitude of medical and personal problems resulting from long-term use.
