Cocaine

The powdered form of cocaine is either inhaled through the nose (snorted), where it is absorbed through the nasal tissue, or dissolved in water and injected into the bloodstream.

The intensity and duration of cocaine’s pleasurable effects depend on the way it is administered. Injecting or smoking cocaine delivers the drug rapidly into the bloodstream and brain, producing a quicker and stronger but shorter-lasting high than snorting. The high from snorting cocaine may last 15 to 30 minutes; the high from smoking may last 5 to 10 minutes.

People who use cocaine often use the drug in a binge pattern—taking the drug repeatedly within a relatively short period of time, at increasingly higher doses. This practice can easily lead to addiction, a chronic relapsing disease caused by changes in the brain and characterized by uncontrollable drug-seeking no matter the consequences. With repeated use, cocaine can cause long-term changes in the brain’s reward system as well as other brain systems, which may lead to addiction. With repeated use, tolerance to cocaine also often develops.

Cocaine affects the body in a variety of ways. It constricts blood vessels, dilates pupils, and increases body temperature, heart rate, and blood pressure. It can also cause headaches and gastrointestinal complications such as abdominal pain and nausea. Because cocaine tends to decrease appetite, chronic users can become malnourished as well. Most seriously, people who use cocaine can suffer heart attacks or strokes, which may cause sudden death. Cocaine-related deaths are often a result of the heart stopping (cardiac arrest) followed by an arrest of breathing.

Crack

Crack is a form of cocaine that has been processed to make a rock crystal (also called “freebase cocaine”) that can be smoked. The crystal is heated to produce vapors that are absorbed into the blood-stream through the lungs.

AMPHETAMINE

Although it is a prescription medication in many countries, unauthorized possession and distribution of amphetamine is often tightly controlled due to the significant health risks associated with uncontrolled or heavy use.
A moderate overdose may induce symptoms including: irregular heartbeat, confusion, painful urination, high or low blood pressure, muscle pain, severe agitation, rapid breathing, tremor, urinary hesitancy, and urinary retention.

An extremely large overdose may produce symptoms such as psychosis, cardiogenic shock, cerebral hemorrhage, circulatory collapse, edema (peripheral or pulmonary), extreme fever, pulmonary hypertension, renal failure, rapid muscle breakdown. Fatal amphetamine poisoning usually also involves convulsions and coma.

Meth……

What does it look like?

Methamphetamine is a crystal-like powdered substance that sometimes comes in large rock-like chunks. When the powder flakes off the rock, the shards look like glass, which is another nickname for meth. Meth is usually white or slightly yellow, depending on the purity.

How is it used?

Methamphetamine can be taken orally, injected, snorted, or smoked.

Immediately after smoking or injection, the user experiences an intense sensation, called a “rush” or “flash,” that lasts only a few minutes and is described as extremely pleasurable.

Snorting or swallowing meth produces euphoria — a high, but not a rush. After the initial “rush,” there is typically a state of higagitation that in some individuals can lead to violent h behavior.

Methamphetamine is addictive, and users can develop a tolerance quickly, needing larger amounts to get high. In some cases, users forego food and sleep and take more meth every few hours for days, ‘binging’ until they run out of the drug or become too disorganized to continue.

Chronic use can cause paranoia, hallucinations, repetitive behavior (such as compulsively cleaning, grooming or disassembling and assembling objects), and delusions of parasites or insects crawling under the skin. Users can obsessively scratch their skin to get rid of these imagined insects.

Long-term use, high dosages, or both can bring on full-blown toxic psychosis (often exhibited as violent, aggressive behavior). This violent, aggressive behavior is usually coupled with extreme paranoia.

Methamphetamine use can also cause strokes and death.
