I am not completely familiar with the effects or in itself with drug abuse, I simply know that there are more "strong" drugs like cocaine, acids, or heroin, or others more "soft" like marijuana or legal drugs like tobacco and alcohol. Cocaine generates a body effect of hardness, acids or heroin hallucinate, sometimes marijuana on its part makes hallucinate depending on the THC concentration of it, alcohol gets drunk and cigar ... Well, the cigar does not produce a momentary effect. But all causes of the long term cause the degeneration of the person at the body level and some to a greater or lesser extent at the brain or consciousness level.
Talking about legal drugs, like the fast food, tea, sugar or coffee, many of us are addicted to this type of drugs. I'm addicted to fast food and soft drinks.
Now, talking about kind of party and celebrations drugs , at 15-16 years old, I started drinking alcohol at parties and at 16 I started to smoke a cigar, and I did this for 5 years, until October 2016 (11th October specifically), after that I stopped drinking and smoking by decision and personal determination. And on the other hand I am a consumer of recreational cannabis.
But I wouldn't speak of drug abuse at all.
Drugs has positive effects on our organisms, and negative effects, degenerating. Just to name a few, in example marijuana, is one of the most famous and in some parts of the world is already being legalized. Medicinal marijuana helps stopping the spread of diseases such as HIV, Alzheimer, epilepsy and glaucoma, reduce insulin levels for people with diabetes, and other benefits with neuronal diseases such as anxiety and depression. In contrast, its non-medicinal or recreational use through combustion affects male sexual capacity, produces respiratory diseases or negatively affects the brain.
Another very famous drug is cocaine. At one time this drug was totally legal. It helps to combat depression, sexual impotence besides being used as an anesthetic. Also among its negative effects are in general the interruption of the irriga
tion of the blood vessels and generation of psychological problems.
Finally, the drug LSD: According to several studies LSD is used for the treatment of alcoholism, helping the patient not to relapse, so that it gives a different perception of life to analyze the situation.
Oppositely to the positive effects it generates, or could provoke anxiety and psychosis
A person prone to psychological disorders has a high risk of having undesirable consequences and disorders directly associated with use.
Here is a list of abstinence effects of some drugs:
1. Alcohol: Tremors, insomnia, sweating, nausea, being able to reach convulsions or Delirium.

The abuse of drugs that degenerate the human being impacts directly on development in the society in which we are immersed, forming part of the same social segregation itself.
I don't know an addict people, but I have shared many times with people who are and the truth is the emaciation of the person on a physiological and mental level given the unconsciousness these people present in front of their own reality.
Under the look and knowledge that a pharmaceutic has on drugs, a comparison can be established between good and bad effects of these on the organism of a human and as a consequence in society. In this way, it is necessary to warn against the harmful effects of drug abuse and even more to achieve a decrease in the statistics regarding the number of drug addicts, how addicted they are or similar factors that converge in an integral appreciation of the level of drug addiction of someone.
