Underline the answers to the following questions while reading the article. 1. Is there any way to predict the effects felt from using marijuana? 2. What can substances sold as marijuana often be mixed with? 3. What are some examples of how people who smoke marijuana regularly can have changes in personality? Marijuana ranks first, followed in order by cocaine, hallucinogens, and heroin. Alcohol remains by far the most popular drug among college students. However, the vast majority of college students (80%) report no drug use in the previous month. B. Nicotine. Valium is also addictive, LSD and marijuana less so. Nicotine is believed to be the most highly addictive psychoactive drug. A. This figure is even lower for drugs that are difficult to obtain or manufacture. Street drugs may be sold in unsafe dosages and are typically mixed or cut with cheaper and often more hazardous substances. Changes in Brain chemistry occur dependent on the method of administration Oral Ingestion Injection (can be into the intramuscular or intravenous) Smoke Inhalation Absorption The quicker the drug reaches the brain the more likely the user is to become dependent. Once a drug reaches the brain, it acts on one or more neurotransmitters, either increasing or decreasing their concentration and actions. 6 Addiction - continued involvement with a substance despite negative consequences Dependence – when the person feels they need the drug ◦ can be physical and/or psychological Tolerance – when the person needs more and more to get the same effect Withdrawal – a series of symptoms that occur when an addict stops using a drug. Relapse – the tendency to return to addictive behavior after a period of abstinence. Euphoria – “high” Synesthesia – an effect where sensory messages are incorrectly assigned (hear a taste, smell a sound) Flashbacks – perceptual distortions and bizarre thoughts that occur after the drug has been eliminated from the body Drugs can be separated into Types and Categories Types of Drugs: ◦ Prescription Drugs ◦ Over-the-Counter (OTC) Drugs ◦ Recreational Drugs alcohol, tobacco, caffeine ◦ Illicit Drugs Illegal Most are psychoactive – changes brain chemistry Stimulants Depressants Opiates Hallucinogens Designer Drugs Inhalants Steroids Most widely used illegal drug in the U.S. Marijuana is derived from the Cannabis Sativa plant Other names include: ◦ Pot, grass, sinsemilla, blunts, mota, yerba, grifa ,Aunt Mary, Boom, Chronic (marijuana alone or marijuana with crack), Dope ganja, Gangster, Hash, Herb, Kif, Mary Jane, Pot, Reefer, Sinsemilla, Skunk, Weed 11 THC (tetrahydrocannabinal) is the main active ingredient in the marijuana plant ◦ THC is the principal mind-altering ingredient ◦ THC travels through the bloodstream to all cells in the body and is stored in the fat cells of the body especially around the lungs, the brain, and the reproductive organs ◦ The strength of marijuana has increased to 10 times the amount of THC since the 1960’s. There are over 400 chemicals in marijuana that break down into over 2,000 chemicals Marijuana can be smoked , inhaled or ingested Smoking provides a direct route to the brain and effects can be felt in minutes ◦ Can reach their peak in 10 to 30 minutes but can linger for 2 to 3 hours THC is fat -soluble ◦ This means it can be stored in the body for long periods of time ◦ Marijuana can be measured in the body up to 30 days after use Marijuana cigarettes contain more carcinogens than tobacco cigarettes ◦ Marijuana contains 50 – 100% more tar than cigarettes ◦ 1 marijuana cigarette = tar of 14 tobacco cigarettes Marijuana also contains carbon monoxide which diminishes oxygen in the blood. People who smoke both marijuana and tobacco dramatically increase their risk of lung diseases. Exposure to second-hand smoke on a regular basis can be stored in the fat cells and can be tested positive as a user. In low doses the effects are strongly influenced by the user’s expectations and past experiences ▶ Changes include: ▶ o Euphoria – “high” o Mood changes o Impaired short-term memory (forgetfulness) o Altered sense of time and space o Reduced concentration and ability to learn o Lack of balance, coordination and reaction time ▶ Other Effects include: o Dilated blood vessels in the eyes (blood-shot eyes) o Hunger and thirst o Increased heart rate Respiratory damage ◦ Chronic bronchitis and asthma ◦ Emphysema Cancer growth Learning problems Impairment of attention and memory Depression Decreased testosterone levels ◦ Decreased sperm count and increased sperm abnormalities Especially harmful during puberty Disrupts the ovulation and menstrual cycle Increase anxiety, panic and paranoia Tolerance and Dependence develops Withdrawal from Marijuana includes: ▶Anger ▶Aggression ▶Irritability ▶Nervousness ▶Restlessness ▶Sleep difficulties ▶Decreased appetite or weight loss Withdrawal can last up to 12 to 15 months. Cocaine is a drug extracted from the Cocoa plant Other names include: ◦ Coke, Flake, Snow, Crack, Coca, Blanca, Perico, Nieve, SodaCot It is sold illegally in 3 forms: ◦ Powder ◦ Crack ◦ Paste Cocaine often diluted ("cut") with a variety of substances, the most common being sugars and local anesthetics. This is done to stretch the amount of the product and increase profits for dealers. Type of Drug: oCocaine is a Central Nervous System Stimulant oStimulants speed up the activity of the nervous and muscular system oCaffeine, amphetamines, nicotine, and ephedrine are also CNS stimulants Snorted in the nose ◦ Absorbed through nasal passages (reaches the brain in 2-3 minutes) Injected into the veins ◦ Using needles (reaches the brain in 20 seconds) Processed and Smoked , also called “Freebased” ◦ Produces a shorter and more intense high ◦ “Crack” is cocaine already in a smokeable form (reaches the brain in 10 seconds) and produces the most intense “high” or “rush” followed by a “crash” Intense but short-lived “high” Cocaine Effects including: ◦ Heart rate increases and irregular heart beat ◦ High blood pressure ◦ Blood vessels constrict ◦ Pupils and bronchial tubes dilate ◦ Increased muscular tension ◦ Increased motor activity ◦ Loss of appetite “High” replaced by a “Crash” in which the user Overdose can cause: can experience irritability, anxiety, agitation, slight depression ▶ Sudden death from excessive CNS stimulation can occur resulting in respiratory paralysis o o o o Convulsions Blood clots Heart attack Stroke ▶ Use during pregnancy o Rapidly passes from mother’s blood stream to placenta of the baby o Increased risk for all types of problems 22 Crack is highly addictive It is common to be addicted to crack after only one use. ◦ This is because crack produces a short but intense high. Smoking it provides a more direct route to the brain. ◦ The high is followed by a severe “crash”. ◦ The high is so short-lived and the “crash” is so low the user takes another hit.

Chapter Nine 35 Altered state of consciousness Altered perceptions, feelings and thoughts Altered sense of time Visual disturbances Mood changes Distorted body perception Dilated pupils Dizziness Weakness Nausea Method of administration: ◦ Typically ingested in forms such as: Impregnated paper typically imprinted with colorful graphic designs Tablets (microdots) Thin squares of gelatin (window panes) In sugar cubes Liquid form (rare) Street Names include: ◦ Acid, Microdol, Sunshine, Boomers During the first hour after ingestion, users may experience visual changes with extreme changes in mood, commonly called a “trip.” LSD users experience a “hallucination” which the user experiences: ◦ Impaired depth and time perception ◦ Distorted perception of the shape and size of objects, movements, colors, sound, touch and the user's own body image ◦ Ability to make sound judgments and see common dangers is impaired, making the user susceptible to personal injury It is possible for users to suffer acute anxiety and depression. Flashbacks have been reported days, and even months, after taking the last dose. Other names include: ◦ Ecstasy, XTC, Adam; MDA Love Drug; MDEA (Eve); MBDB, hug, beans Ecstasy is a synthetic drug The majority of MDMA is produced in laboratories in Europe and then smuggled into the United States. It produces nerve cell damage that can result in psychiatric disturbances and long-term cognitive impairments. MDMA is usually distributed in tablet form and ingested ◦ Many of these tablets are imprinted with designs or commercial logos. The effects of MDMA are felt within 30-45 minutes, peaking at 60-90 minutes, and last 4-6 hours. Produces both stimulation and hallucination effects. Associated with increased energy, sensual arousal and enhanced tactile sensations.

Abuse of prescription drugs can produce serious health effects, including addiction, and can be life threatening. Opioids: ◦ Hydrocodone (Vicodin®), Oxycodone (OxyContin®), Propoxyphene (Darvon®), Hydromorphone (Dilaudid®), Meperidine (Demerol®), and Diphenoxylate (Lomotil®) Central Nervous System Depressants: ◦ Barbiturates (Nembutal®), Benzodiazepines such as diazepam (Valium®) and Alprazolam (Xanax®). Stimulants: ◦ Dextroamphetamine (Dexedrine®), Methylphenidate (Ritalin® and Concerta®), and Amphetamines (Adderall®). A 2006 study reported that overdoses from opioid painkillers kill more people than overdoses from either cocaine or heroin. The National Institutes of Health (NIH) estimates that close to 20 percent of people (48 million) over the age of 12 in the U.S. have used prescription drugs for non-medical purposes. More than 200,000 visits to emergency rooms around the country each year are because of prescription drug abuse. What are anabolic steroids? ◦ Anabolic steroids are synthetic drugs derived from hormones, primarily testosterone. ◦ Anabolic steroids are considered ergogenic drugs which are drugs used to enhance athletic performance. ◦ Anabolic steroids are designed to diminish the androgenic effects of testosterone while amplifying the anabolic effects. Increased anabolic effects produce muscle growth. Decreased androgenic effects produce diminished expression of sexual characteristics. Anabolic steroids mimic the effects of the male sexual hormone, testosterone. Anabolic steroids work only in conjunction with physical training and a high-protein, high-calorie diet. Use of steroids can produce a significant increase in lean muscle mass, strength and muscle endurance. Weight lifters and body builders to produce gains for competitions Specific athletes requiring strength such as football players, throwing events in track and field (shot-put, discus, hammer throw) and baseball players. Specific athletes requiring speed such as swimmers and running events in track and field (sprinters). People who just want to get larger muscles for self-gratification. Increase in muscle mass Acne Jaundice (yellowing of the skin) Trembling Swelling of the feet and ankles Bad breath Reduction in HDL (good cholesterol) High blood pressure Cardiovascular damage Liver damage and cancers Aching joints Increased chance of injury to tendons Increase in aggression and temper “Roid Rage” *Many of these effects are irreversible. Because of the decrease androgenic effects of testosterone in Anabolic steroids, several sexual side effects are possible: For Males: ◦ ◦ ◦ ◦ ◦ ◦ ◦ Shrinking of the testicles Reduced sperm count Impotence Baldness Difficulty in urinating Development of breasts Enlarged prostate For Females: ◦ Growth of facial hair ◦ Changes in menstruation ◦ Enlargement of the clitoris ◦ Deepened voice ◦ Breast reduction
