 Dear students, in this module we are going to talk about a very important issue which is of drug abuse in Pakistan. As you know that drugs are considered pretty much dangerous not only for the health but also for the behavioural aspects of the individual and it is not merely affecting the individual who is consuming those drugs. It is affecting his or her surroundings as well, it is affecting his or her family members as well both economically as well as emotionally. So let's see that what are the statistics of drug abuse in Pakistan and what kind of problems do we face because of that. So around 4.77 million people use drugs in Pakistan so these are the huge statistics and almost 1 million people are addicts of heroin which is considered very dangerous drug in Pakistan and 40,000 people add up to the pool of drugs, drug users annually. Many of drug users are between the age of 25 and 39 years so these are the most productive years of any individual so if someone in these years become an addict it means that his or her productive years of life are lost. So here is the glimpse of the drug addict community that you see that they are usually gathered around in order to take part in this drug consumption activity. So before we go further let us first define that what do we call the drug abuse whether it's a drug consumption or it's a drug intake and why it is considered an abuse. So drug abuse refers to the use of certain chemicals for the purpose of creating pleasurable effects on the brain. There are 190 million drug users around the world so this man is rising especially among the young adults who are under the age of 30. So these chemical reactions are actually producing some consequences not only on the health but also on the functioning of your brain. So here you see a reflection of one of the methods of drug intake which is by using injections. There are fewer kinds of drug abuse categories or categories of drugs one of them is the depressants. These cause the depression for the brain's faculties when we consume these drugs our brain sees to function properly and such drugs include sleeping pills and heroin etc. So here is the reflection of these depressants and then we have the stimulants these cause the stimulation of the brain giving rise to the alternates and an increased burst of activities. So the consequences of stimulants include the raising of blood pressure, nausea or vomiting and certain behavioral changes one of them can cause a lot of aggression in the individual who is consuming the drugs. And also we have the hallucinogens these drugs cause hallucinations and an out of the world feeling disassociation from one's own personality when you consume these drugs you do not feel yourself rather you feel someone out of the world. So hallucinogens cause distorted sensory perception, delusion and paranoia. So these drugs can have a lot of consequences on not only on the health of the individual but on the social life as well.
