The short-term effects of marijuana include problems with memory and learning, distorted perception, loss of coordination, increased heart rate and anxiety. The long-term effects of these drugs include slowed and slurred speech, constricted pupils, droopy eyelids, impaired night vision, sedation, coma, addiction, convulsions, heart failure, paranoia, hallucinations, delusions, loss of interest in sex, marijuana even contains some of the same, and sometimes even more of the cancer-causing chemicals found in tobacco. These drugs can hurt you and those who surround you. I don't understand why would anyone go through the risk of dying of overdosed and just the fact of addiction is a nightmare that many choose to live every day of their lives. Drugs bring me to my next issue which is why some people think that alcohol and tobacco should be illegal. Let me start by saying that millions of lives would be safe if smoking and drinking was illegal. Is it fair for innocent people to die because of a drunk driver or because of second hand smoke? How much do we value the lives of others and our own?. You don't need to drink much alcohol before your ability to dive becomes impaired. The more heavily you drink, the greater the potential for problems at home, at work, with friends, and even with strangers. One of my family member was an alcoholic and I know that they face a lot of problems like arguments with the family or friends, loss of employment due to absences or decreased productivity, committing or being the victim of violence and also alcohol can cause a range of birth defects, the most serious being fetal alcohol syndrome F.A.S. (physical abnormalities, mental impairment). Children born with alcohol-related birth defects can have lifelong learning and behavior problems. Some problems, like those I mentioned above, can occur after drinking over a relatively short period of time. But other problems such as liver disease, heart disease, certain forms of cancer, and pancreatitis often develop more gradually and may become evident only after long-term heavy drinking.
