What are the dangers from using drugs?

Some people think everyone who takes drugs will end up dead. Others seem to think that drug use is not dangerous at all. The truth is somewhere in between...

The dangers

Drug use can never be 100 per cent safe but it is not always as dangerous as many people think. The dangers of drug use depend on drug, set and setting factors.
The drug bit is everything connected with the drug and how it is used. The set bit is everything connected with the person who is using the drugs. The setting bit is about what the person is doing at the time, where they are, the environment they live in etc.
The basic principal is that drug dangers are the result of interactions between drug, set and setting.

The Dangers Of Drug Abuse

By Janine Tassi
Drug use is a huge problem; we are a drug culture, and literally thousands of substances are used extensively.  Western medicine is likewise a drug-orientated system.  We consume billions of pills yearly and spend billions of rands on then.  These figures do not even include the everyday use of caffeine, alcohol, and nicotine.
Drug problems are common, and there are really no stereotypical drug addicts; they can be the affluent businessman, the housewife, the down-and-out “street’ person, or anyone under pressure or with unmet psychological needs.  Drug and substance abuse are an individual, family, and worldwide problem that can affect young and old, men and women.
Any of the thousands of prescription and over-the-counter (OTC) drugs currently available and in common use can be toxic, especially when too much is used or when they are used for too long.  OTC products are more easily abused than pharmaceuticals because they can be readily obtained, and are usually less toxic.

Dangers Toxic elements in tobacco smoke

Toxic elements in tobacco smokeHeavy metals such as arsenic, cadmium, and lead have been detected in tobacco smoke, by showing that the toxic elements could propagate to distances varying natural airflow.A burning cigarette produces more than 4000 chemicals, many of which are toxic and about 40 cause cancer. These compounds remain in the air as environmental tobacco smoke is inhaled by others in the region. There are two types of cigarette smoke, the cigarette smoke that comes out of the mouth of the main smokers and sidestream smoke from the burning end of the cigarette.

Dangers liquor for health

Alcohol (ethanol) contained in any liquor will be directly absorbed by the body after gulped.  
In fact because it does not have to be digested first, then alcohol has started to absorb even while still in the mouth. Because very brief alcohol is immediately circulated throughout the body, particularly in parts of the body that has a very large vessels.  
For example, the brain.For that reason, all the reactions in the body and behavior are controlled by the brain is affected by alcohol. The experts have made the statement between the amount of alcohol you drink to the size of the brain is affected.  
 For example, if someone who has a body weight of 70 kg with an empty stomach to drink 720 cc of beer (2 bottles), or 45 cc whiskey (1-2 shot), the alcohol in the blood will reach the amount of 50 mg / dl or with concentrations of 0 , 05%.  
 At this level of the brain that is affected is the outer layer (cortex) which is the anxiety control center, so it will look happy and calm. 

Dangers of Secondhand Smoke

 Researchers have known that secondhand smoke can be just as dangerous for nonsmokers as smoking is for smokers, but now there's fresh evidence quantifying just how hazardous the after burn from cigarettes can be, and how quickly it affects your body. Scientists at the Oregon Department of Health documented for the first time an hourly buildup of a cancer-causing compound from cigarette smoke in the blood and urine of nonsmokers working in bars and restaurants in the state.
