What are the side effects of Marijuana?
Enhanced cancer risk
Decrease in testosterone levels and lower sperm counts for men
Increase in testosterone levels for women and increased risk of infertility
Diminished or extinguished sexual pleasure
Psychological dependence requiring more of the drug to get the same effect
What are the effects of Marijuana on Men?
Marijuana is the most common drug used by adolescents in America today. Marijuana affect the parts of the brain which controls the sex and growth hormones. In males, marijuana can decrease the testosterone level. Occasional cases of enlarged breasts in male marijuana users are triggered by the chemical impact on the hormone system. Regular marijuana use can also lead to a decrease in sperm count, as well as increases in abnormal and immature sperm. Marijuana is a contributing factor in the rising problem of infertility in males. Young males should know the effects and potential effects of marijuana use on sex and growing process before they decide to smoke marijuana.
What are the effects of Marijuana on Women?
Just as in Males, marijuana effects the female in the part of the brain that controls the hormones, which determines the sequence in the menstrual cycle. Its been said that females who smoked or used marijuana on a regular basis had irregular menstrual cycles, the female hormones were depressed, and the testosterone level was raised. Even though this effect may be reversible, it may take several months of no marijuana use before the menstrual cycles become normal again.
Mothers who smoke marijuana on a regular basis have been reported of having babies with a weak central nervous system. These babies show abnormal reactions to light and sound, exhibit tremors and startles, and have the high-pitched cry associated with drug withdrawal. Occurring at five times the rate of Fetal Alcohol Syndrome, Fetal Marijuana Syndrome is a growing concern of many doctors. Furthermore, doctors worry that children born to "pot-head" mothers will have learning disabilities, attention deficits and hormonal irregularities as they grow older, even if there are no apparent signs of damage at birth. Pregnant or nursing mothers who smoke marijuana should talk to their doctors immediately.
What are the effects of Marijuana on the brain?
Researchers have found that THC changes the way in which sensory information gets into and is acted on by the hippocampus. This is a component of the brain's limbic system that is crucial for learning, memory, and the integration of sensory experiences with emotions and motivations. Investigations have shown that neurons in the information processing system of the hippocampus and the activity of the nerve fibers are suppressed by THC. In addition, researchers have discovered that learned behaviors, which depend on the hippocampus, also deteriorate. Recent research findings also indicate that long-term use of marijuana produces changes in the brain similar to those seen after long-term use of other major drugs of abuse.
What are the effects of Marijuana on the lungs?
Someone who smokes marijuana regularly may have many of the same respiratory problems that tobacco smokers have. These individuals may have daily cough and phlegm, symptoms of chronic bronchitis, and more frequent chest colds. Continuing to smoke marijuana can lead to abnormal functioning of lung tissue injured or destroyed by marijuana smoke.
Regardless of the THC content, the amount of tar inhaled by marijuana smokers and the level of carbon monoxide absorbed are three to five times greater than among tobacco smokers. This may be due to the marijuana users inhaling more deeply and holding the smoke in the lungs.
What are the effects of Marijuana on heart rate and blood pressure?
Recent findings indicate that smoking marijuana while shooting up cocaine has the potential to cause severe increases in heart rate and blood pressure. In one study, experienced marijuana and cocaine users were given marijuana alone, cocaine alone, and then a combination of both. Each drug alone produced cardiovascular effects; when they were combined, the effects were greater and lasted longer. The heart rate of the subjects in the study increased 29 beats per minute with marijuana alone and 32 beats per minute with cocaine alone. When the drugs were given together, the heart rate increased by 49 beats per minute, and the increased rate persisted for a longer time. The drugs were given with the subjects sitting quietly. In normal circumstances, an individual may smoke marijuana and inject cocaine and then do something physically stressful that may significantly increase risks of overload on the cardiovascular system.
What are the effects of heavy Marijuana use on learning and social behavior?
A study of college students has shown that critical skills related to attention, memory, and learning are impaired among people who use marijuana heavily, even after discontinuing its use for at least 24 hours. Researchers compared 65 "heavy users," who had smoked marijuana a median of 29 of the past 30 days, and 64 "light users," who had smoked a median of 1 of the past 30 days. After a closely monitored 19- to 24-hour period of abstinence from marijuana and other illicit drugs and alcohol, the undergraduates were given several standard tests measuring aspects of attention, memory, and learning. Compared to the light users, heavy marijuana users made more errors and had more difficulty sustaining attention, shifting attention to meet the demands of changes in the environment, and in registering, processing, and using information. The findings suggest that the greater impairment among heavy users is likely due to an alteration of brain activity produced by marijuana.
Longitudinal research on marijuana use among young people below college age indicates those who used have lower achievement than the non-users, more acceptance of deviant behavior, more delinquent behavior and aggression, greater rebelliousness, poorer relationships with parents, and more associations with delinquent and drug-using friends.
What are the effects of Marijuana on pregnant women?
Any drug of abuse can affect a mother's health during pregnancy, and this is a time when she should take special care of herself. Drugs of abuse may interfere with proper nutrition and rest, which can affect good functioning of the immune system. Some studies have found that babies born to mothers who used marijuana during pregnancy were smaller than those born to mothers who did not use the drug. In general, smaller babies are more likely to develop health problems.
A nursing mother who uses marijuana passes some of the THC to the baby in her breast milk. Research indicates that the use of marijuana by a mother during the first month of breast-feeding can impair the infant's motor development (control of muscle movement). Research also shows more anger and more regressive behavior (thumb sucking, temper tantrums) in toddlers whose parents use marijuana than among the toddlers of non-using parents
Alcohol Side Effects
Since alcohol so easily permeates every cell and organ of the body, the physical effects of chronic alcohol abuse are wide-ranging and complex. Large doses of alcohol invade the body's fluids and interfere with metabolism in every cell. Alcohol damages the liver, the central nervous system, the gastrointestinal tract, and the heart. Alcoholics who do not quit drinking decrease life expectancy by 10 to 15 years.
Alcohol also can impair vision, impair sexual function, slow circulation, cause malnutrition, cause water retention (resulting in weight gain and bloating), lead to pancreatitis and skin disorders (such as middle-age acne), dilate blood vessels near the skin causing "brandy nose," weaken the bones and muscles, and decrease immunity.
Persons suffering with alcohol abuse finally grow obsessed with alcohol to the exclusion of almost everything else. They drink despite the pleading of family and the stern advice of doctors. They may begin round-the-clock drinking despite an inability to keep down the first drinks in the morning. Although relationships with family and work may become completely severed, nothing, not even severe health problems, is enough to deter drinking.
The late-stage alcoholic suffers a host of fears, including fear of crowds and public places. Constant remorse and guilt is alleviated with more drinking. On top of mental disturbances, debts, legal problems, and homelessness may complicate his or her life. Late stage addiction is characterized by cirrhosis and severe withdrawal symptoms if alcohol is withheld (shakes, delirium tremens, and convulsions). Without hospitalization or residency in a therapeutic community, late-stage alcoholics usually succumb to insanity and death.
People suffering alcoholism do not have to "hit bottom" and reach the extreme late stages of alcoholism to decide to get help. Many men and women have recognized their alcohol problems before they lost their jobs or families, or began drinking in the morning, suffered DTs, or had to be hospitalized. For them, the labels "early stage," late stage," "problem drinker," or "alcoholic" were less important than the fact that their growing powerlessness over alcohol was causing them pain.
The liver breaks down alcohol in the body and is therefore the chief site of alcohol damage. Liver damage may occur in three irreversible stages.
Fatty Liver. Liver cells are infiltrated with abnormal fatty tissue, enlarging the liver.
Alcoholic Hepatitis. Liver cells swell, become inflamed, and die, causing blockage. (Causes between 10 and 30 percent mortality rate.)
Cirrhosis. Fibrous scar tissue forms in place of healthy cells, obstructing the flow of blood through the liver. Various functions of the liver deteriorate with often fatal results. (Found in 10 percent of alcoholics.)
A diseased liver:
Cannot convert stored glycogen into glucose, thus lowering blood sugar and producing hypoglycemia.
Inefficiently detoxifies the bloodstream and inadequately eliminates drugs, alcohol, and dead red blood cells.
Cannot manufacture bile (for fat digestion), prothrombin (for blood clotting and bruise prevention), and albumin (for maintaining healthy cells).
Alcohol in the liver also alters the production of digestive enzymes, preventing the absorption of fats and proteins and decreasing the absorption of the vitamins A, D, E, and K. The decreased production of enzymes also causes diarrhea.
THE BRAIN AND CENTRAL NERVOUS SYSTEM
Alcohol profoundly disturbs the structure and function of the central nervous system, disrupting the ability to retrieve and consolidate information. Even moderate alcohol consumption affects cognitive abilities, while larger amounts interfere with the oxygen supply to the brain, a possible cause of blackout or temporary amnesia during drunkenness. Alcohol abuse destroys brain cells, producing brain deterioration and atrophy, and whether the organic brain damage and neuropsychological impairment linked to alcohol can be reversed is unknown. Alcohol also alters the brain's production of RNA (a genetic "messenger"), and serotonin, endorphins, and natural opiates whose function may be linked to the addictive process.
A neurological disorder called Wernicke-Korsakoff's syndrome results from vitamin B deficiencies produced by alcoholism and the direct action of alcohol on the brain. Symptoms of this condition include amnesia, loss of short-term memory, disorientation, hallucinations, emotional disturbances, double vision, and loss of muscle control. Other effects include mental disorders such as increased aggression, antisocial behavior, depression, and anxiety.
The Digestive System
Large amounts of alcohol may inflame the mouth, esophagus, and stomach, possibly causing cancer in these locations, especially in drinkers who smoke. Alcohol increases the stomach's digestive enzymes, which can irritate the stomach wall, producing heartburn, nausea, gastritis, and ulcers. The stomach of a chronic drinker loses the ability to adequately move food and expel it into the duodenum, leaving some food always in the stomach, causing sluggish digestion and vomiting. Alcohol may also inflame the small and large intestines.
The Heart
Moderate daily drinking may be good for the heart, but for many the risks outweigh the benefits. Even one binge may produce irregular heartbeats, and alcohol abusers experience increased risk of high blood pressure, heart attacks, heart arrhythmia, and heart disease. Alcohol may cause cardiomyopathy (a disease of the heart muscle). Cessation of drinking aids recovery from this condition.
