NICOTINE! Nicotine is a toxic colorless or yellowish oily liquid that is the chief active constituent of tobacco. It acts as a stimulant in small doses, but in larger amounts blocks the action of autonomic nerve and skeletal muscle cells. Nicotine is also used in insecticides. Effects of nicotine.
Most often the crystalline powder is sprinkled on a leafy substance (mint, tobacco, or marijuana) and then smoked in rolled cigarettes. Some street names for the drug are Angel Dust, Ozone, Wack, and Rocket Fuel. When snorted or smoked it rapidly passes to the brain to disrupt vision. It alters the action of dopamine which is a neurotransmitter responsible for the euphoria. Physical effects at a low PCP dose, which is 5 mg or less, are shallow,
Lumbricalis variegates cardio vascular system has a myogenic nature(myogenic-depolarisation impulses for heartbeats originating in muscle cells), the dorsal and ventral blood vessels have peristaltic pumps (Halfmann & Crisp 2011). The chemicals chosen as the treatment is ethanol and nicotine, it is assumed that ethanol will slow the pulse rate in the cardio vascular system and that nicotine will speed it up, because of these stimulant and depressant nature. Materials & Method: * Blackworms Lumbricalis variegates (35) * Petri dishes (8) * Pipettes (8) * Paper towel * Recovery bowl * Microscope * Stopwatch * Slides
Heroine Heroin (diacetylmorphine or morphine diacetate), also known as diamorphine, is an opiate analgesic synthesized by C.R. Alder Wright in 1874 by adding two acetyl groups to the molecule morphine found in the opium poppy. It is the 3,6-diacetyl ester of morphine, and functions as a morphine prodrug (meaning that it is metabolically converted to morphine inside the body in order for it to work). When used in medicine it is typically used to treat severe pain, such as that resulting from a heart attack or a severe injury. The name "heroin" is only used when being discussed in its illegal form.
Phenylalanine also disrupts amino acid metabolism, hormonal equilibrium, and nerve functions. Aspartic acid is believed to function as an excitatory neurotransmitter in the central nervous system (CNS). Methanol gets converted to formate, it is either excreted or it gets accumulated in the body to form formaldehyde, diketopiperazine (a carcinogen), and other potent toxic products.

Some chemotherapy regimens are notorious for causing terrible bouts of nausea and vomiting. Both THC and marijuana have been explored as anti nausea medication. Smoking marijuana gives one the desired effect in a matter of minutes and relieves the symptom very quickly
Anti depressants such as MAOI’s which increase the available amount of nor adrenaline in the brain, were found to be effective for elevating the symptoms of depression. So when noradrenalin is increased in the brain, symptoms of depression get better, suggests that it is chemicals that are the root cause of depression. This idea is also found in the results of taking reserpine, a drug used to treat high blood pressure. Depression is a unwanted side effect of this drug, as this drug acts by lowering levels of nor adrenaline. So again strongly suggests that low activity noradrenaline, is a factor contributing to the cause of depression.
And women are considered to have excited eith the positive auspects of sheesha smoking that is carried away. The sheesha includes high contents of carbon monooxidelike carcinogens tobacco specific nitrosa mines,48. This exposure leads to a variety of adverse health effects, includ ing cancer, cardiovascular disease, and addiction.49 Waterpipe users may also be exposed to these smoke constituents, though little research addresses this issue. With regard to other constituents, waterpipe smoke produced by a machine contains significant amounts of dangerous consti tuents, including nicotine and heavy metals such as arsenic, cobalt, chromium, and lead." 51 52 Under normal waterpipe use conditions, the smoke produced from a single waterpipe use contains approximately the same amount of nicotine free, dry paniculate matter ("tar") as 20 cigarettes.11 How ever, the tar produced by a waterpipe may differ from that produced by a cigarette,53 because tobacco in a waterpipe is heated to about half the temperature (that is, 450?C) of tobacco in a cigarette.
Also, one of the main ingredients called THC as a hallucinogen will disturb users’ sensory experience. “THC causes animals to misjudge events,” reported Ronald Siegel (Myers116), which means that THC would increase the dose of cocaine Houston takes because after taking marijuana, Houston was unable to realize that she had overdosed on cocaine and kept taking it. Therefore, taking marijuana and cocaine at the same time results in a chemical reaction to drive users take more cocaine, which strengthen depressed feelings eventually. Xanax, as an antianxiety drug, relieves users’ nervous tension by slowing down the movement of chemicals in the brain that may cause unbalance of chemicals, and it will calm central nervous system to cause sleepiness as well. So the dizziness caused by Xanax makes Whitney Houston unconscious when she was in a
Brett Ingram Dr. Vails English 1301 10 October 2013 Drugs are not always what they seem 3, 4-methylenedioxymethamphetamine (MDMA) is a hallucinogenic chemical that has been banned across the United States. Molly is the street name for pure MDMA and although Molly is very similar to Ecstasy, they are in fact different. Molly is pure MDMA and is not mixed with any other illegal substances. One can tell by the color and the taste if something extra has been added into the capsule, but is MDMA a negative thing, or are there actually positive aspects to this drug? This “rave drug” is actually proven to be good for one’s mental health.
