  • 2. INTRODUCTION Lots of people are tempted by the excitement or escape that drugs seem to offer. Many teens use drugs because they're depressed or think drugs will help them escape their problems. Drugs don't solve problems — they simply hide feelings and problems. When a drug wears off, the feelings and problems remain, or become worse. Drugs can ruin every aspect of a person's life.
  • 3. DEFINITION Drugs Of A drug is any substance, solid, liquid or gas, that brings about physical and/or psychological changes. The drugs of most concern in the community are those that affect the central nervous system. They act on the brain and can change the way a person thinks, feels or behaves.

Stimulants increase heart rate, body temperature and blood pressure. Other physical effects include reduced appetite, dilated pupils, talkativeness, agitation and sleep disturbance.
  • 8. y #2 : Categor DEPRESSANTS rugs D Depressants Depressants slows down, or depresses, the functions of the central nervous system . In moderate doses, depressants can make you feel relaxed. In larger doses, depressants can cause unconsciousness by reducing breathing and heart rate. A person's speech may become slurred and their movements sluggish and uncoordinated.
  • 9. y #3 : Categor Hallucinogens HALLUCINOGEN rugs D Hallucinogenic drugs distort the user's perceptions of reality. The main physical effects are dilation of pupils, loss of appetite, increased activity, talking or laughing, jaw clenching, sweating and sometimes stomach cramps or nausea. Drug effects can include a sense of emotional and psychological euphoria and well-being. Visual, auditory and tactile hallucinations may occur, causing users to see or hear things that do not actually exist.

  • 12. EFFECTS Drugs Of • Stimulants – Caffeine • Causes blood sugar, or blood glucose, to be released from storage through the effects of the adrenal hormones. Requires your pancreas to over-work. • Dehydration • Increased heart rate • Insomia • Peptic ulcer irritant • Headache • Increase on speed depending on skillset

  • 14. EFFECTS Drugs Of • Hallucinogen – LSD • Delusions • Visual hallucinations • An artificial sense of euphoria or certainty • Distortion of one’s sense of time and identity • Impaired depth perception • Impaired time perception, distorted perception of the size and shape of object, movements, color, sounds, touch and the user’s own body image • Severe, terrifying thoughts and feelings • Fear of losing control • Panic attacks • Flashbacks, or a recurrence of the LSD trip, often without warning long after taking LSD • Severe depression or psychosis
  • 15. EFFECTS Drugs Are On en You Wh VIDEO
  • 16. COGNITIVE FACTORS • MEMORY – Bad • Alcoholism can lead to brain cell death, short-term memory 'blackouts' and something called 'Korsakoff's Syndrome' which is a form of severe amnesia. Smoking(nicotine) is a cause of stroke which can cause shortterm memory loss and can trigger dementia. – Good : • • Mild stimulants can help us concentrate which in turn might also improve our learning abilities. ATTENTION – Bad: • • Steering an automobile is adversely affected by alcohol, as alcohol affects eye-to-hand reaction times, which are superimposed upon the visual effects. Significant impairment and deterioration of steering ability begin at approximately .03 to .04% Blood Alcohol Concentrations and continue to deteriorate as Blood Alcohol Concentration rises. Almost every aspect of the brain’s information-processing ability is impaired by alcohol. Alcohol-impaired drivers require more time to read street signs or respond to traffic signals than unimpaired drivers. Research on the effects of alcohol on the performance of automobile and aircraft operators shows a narrowing of the attention field beginning at .04% blood alcohol concentration. Narrows the visual field, reduces resistance to glare, interferes with the ability to differentiate intensities of light, and lessens sensitivity to colors.
  • 17. COGNITIVE FACTORS • LANGUAGE – For instance, the drug deprenyl inhibits manoamine oxidase (MAO). This increases the stores of dopamine and slows the progression of Parkinson's disease. In higher doses, deprenyl enhances the effects of dopamine on behavior. • DECISSION MAKING – Understanding more about the orbitofrontal cortex also is important for understanding disorders such as addiction that seem to involve maladaptive decision-making and learning. Cocaine in particular seems to have long-lasting effects on the orbitofrontal cortex.
  • 18. CONCLUSION • Addiction is a chronic, often relapsing brain disease that causes compulsive drug seeking and use despite harmful consequences to the individual who is addicted and to those around them. Drug addiction is a brain disease because the abuse of drugs leads to changes in the structure and function of the brain. No single factor can predict whether or not a person will become addicted to drugs. Risk for addiction is influenced by a person’s biology, social environment, and age or stage of development. The more risk factors an individual has, the greater the chance that taking drugs can lead to addiction. I agree that drugs do effect the daily cognitive performance as every consumption or intake can lead you to a higher addiction stage. All I have to say : You can lead a horse to water, but you can't make him drink THINK FOR YOURSELF
