what is cannabis? |
what is cannabis? Cannabis is a drug that comes from Indian hemp plants such as Cannabis sativa and Cannabis indica. The active chemical in cannabis is THC (delta-9 tetrahydrocannabinol). Cannabis is a depressant drug. Depressants do not necessarily make the person feel depressed. Rather, they affect the central nervous system by slowing down the messages going between the brain and the body .Cannabis comes from the plant cannabis sativa. It is commonly referred to as marijuana, mull, weed, dope, grass, ganja, skunk aand pot and gained popularity in Australia during the 1960s and 1970s as part of the hippie era. Cannabis is usually smoked as a „joint“ or through a „bong“. When young people are depressed they may feel hopeless or overwhelmed by despair. Some may feel that using cannabis will help them through tough times. But it is only likely to make things worse. Regular use of cannabis may produce a number of short-term effects including paranoia, confusion and increased anxiety. There aare some young people for whom cannabis use is more serious. Young people with a psychotic illness such as schizophrenia are believed to be more likely to experience a psychosis. A psychosis is a condition where the person loses contact wwith reality and may hear voices or see things that are not there, believe things that are not true, and have jumbled thoughts and strange behaviour. posible effects Use of cannabis products may cause the following: Euphoria followed by relaxation Changes in appetite Loss of coordination More vivid sense of taste, sight, smell, and hearing Panic reactions Impaired short-term memory, shortened attention span, and delayed reflexes Birth defects, if used during pregnancy Fast heart rate and pulse Breathing problems Relaxed inhibitions Disoriented behavior Bloodshot eyes Dry mouth View Poll Results: Should cannabis be legalized? yes-972people-88.20% no-66people-5.99% maybe-45people-4.08% none of the above-19people-1.72% so 88.20%peple wanna cannabis be legalized….<<129words>> If anyone of us is asked about what sort of life he wants to live, he will immediately ssay: a happy life without problems. This is why people do their best to avoid trouble in their daily lives. Sometimes problems and reasons behind them are so great that sufferers find it too hard to bear. So they try to find the easiest way to escape from their plight. They lose control and think drugs are the only way to forget everything<<81>> Children start on “soft” drugs such as hashish or marijuana, moving on to speed and ecstasy, and finally tto “hard” drugs such as heroin. Some people say that there is no drug problem in my hometown, as it is too small for this. But if you look around more carefully, you will see that this problem is everywhere. I think that drugs have spread all over the world. Almost every teenager has used some kind of drugs, but there are many youngsters who take dozes of drugs every day or even more often. As a rule, if there are buyers, there are sellers as well. All you need is money. There were some programs to fight drug abuse in my town. To be more specific, there were some competitions and lectures against drugs. All students took part in these lectures. The drug problem in Lithuania in general is much bigger than in my native town. In biggest cities problem is huge. There are many homeless young people who live with drugs. How we could help them?<<200>> The first thing we have to do is to learn to listen. One ray of hope is the dedicated work performed by social workers, who should spend their time offering children and young people a new perspective. Social workers could visit the pplaces where young people are likely to be hanging out every day to try to make contact and gain their confidence. People all over the world close their eyes to the fate of these youngsters only too often, or discriminate against them because they have no jobs, use drugs. And if we are honest, which one of us has ever seriously questioned the stories behind these young people’s existence? To sum it up, I think its better not even to try drugs, because you can become a drug addict. Drugs really change people. They lose interest in everything, they have no friends, they only care about the next doze. Do you want to live like that? <<156>> Drug Dependence, psychological and sometimes physical state characterized by a compulsion to take a drug in order to experience its psychological effects Drug Dependence , psychological and sometimes physical state characterized by a compulsion to take a drug in order to experience its psychological effects. Psychological dependence, or habituation, is present when the compulsion to take a drug is strong, even in the absence of physical withdrawal symptoms. The drugs that are commonly abused, besides substances such as alcohol and tobacco, can be grouped iinto six classes: the opioids, sedative -hypnotics, stimulants , hallucinogens, cannabis , and inhalants. Opioids The class of opioids includes drugs derived from opium (such as morphine and heroin) and its synthetic substitutes (such as methadone). Medically, morphine is a potent pain reliever; indeed, it is the standard by which other pain-relieving drugs are measured. It and other opium derivatives also suppress coughing, reduce movements of the intestine (providing relief from diarrhoea), and induce a state of psychological indifference. Heroin, a preparation synthesized from morphine, was introduced in 1898 as a cough suppressant and nonaddicting substitute for morphine. The addictive potential of heroin was soon recognized, however, and its use was prohibited in many countries, even in medical practice. Users report that heroin produces a “rush” or a “high” immediately after it is taken. It also produces a state of profound indifference and may increase energy. Opioids produce different effects under different circumstances. The drug taker’s past experience and expectations have some influence, as does the method of administering the drug (by injection, ingestion, or inhalation). Symptoms of withdrawal include kicking movements in the legs, anxiety , insomnia , nausea, sweating, cramps, vomiting, diarrhoea, and fever . During the 1970s, when scientists isolated substances called enkephalins, naturally occurring opiates in the brain, they discovered what many believe to be the reason behind physical dependence on opioids—that is, the drugs are thought to mimic the action of enkephalins. If true, this hypothesis suggests that physical dependence on the opioids may develop in those who have a deficiency of these natural substances. Stimulants Commonly abused stimulants are cocaine and drugs of the amphetamine family. Cocaine, a white, crystalline powder with aa bitter taste, is extracted from the leaves of the South American coca bush. It is used medically to produce anaesthesia for surgery of the nose and throat and to constrict blood vessels and reduce bleeding during surgery; but abuse, which increased considerably in the late 1970s, can lead to severe physiological and psychological problems. A highly addictive, smokable form of cocaine, “crack”, appeared in the 1980s. Amphetamines, introduced in the 1930s for the treatment of colds and hay fever ,, were later found to affect the nervous system. For a while they were commonly used as an appetite suppressant by people trying to lose weight. Today their use is restricted primarily to the treatment of narcolepsy , a sleep ddisorder characterized by sudden sleep attacks throughout the day, and of hyperactivity in children, in whom amphetamines produce a calming effect. For adults, however, amphetamines rightfully earn their common name, “speed”. These drugs heighten alertness, elevate mood, and decrease fatigue and the need for sleep, but they often make users irritable and talkative. Both cocaine and amphetamines, after prolonged daily use, can produce a psychosis similar to acute schizophrenia . A designer drug, 3,4-methylene dioxymethamphetamine, also know as “Ecstasy” or “E”, gives users a great sense of wellbeing; affection for all those around them; increased energy; and, sometimes, hallucinations. Associated with rave culture , its adverse effects can make users feel ill or experience a sense of loss of control, ddehydration, and long-term memory and weight loss. There have been some deaths associated with taking Ecstasy and other drugs at raves. Tolerance to both the euphoric and appetite-suppressing effects of amphetamines and cocaine develops rapidly. |
