There are many drugs in the world. There are some that are used for medical purposes and some that are used for recreational purposes. All drugs have side effects that can harm a person, but the most dangerous drug that is out there is heroin.
This drug is injected into one's veins and has a number of problems that can go along with having it in one's system. One of the issues with heroin is that it is a highly addictive drug, and it is hard to withdraw from. Some users of heroin die from when they are trying to withdraw and rehab from the drug.
When talking about dangerous drugs, heroin always comes to mind because of the typical strung-out addict stigma attached to it. It is also very dangerous because it is injected, which could produce a plethora of health problems that could kill you.
It is also highly addictive, and many cases of death during withdrawal have been reported. Cocaine is another highly addictive substance. It usually makes the person feel powerful, which could also lead to dangerous situations. This drug can cause a heart attack or stroke due to elevated blood pressure, and could also lead to respiratory failure if it is smoked. Methamphetamines are another class of seriously dangerous drugs. One of the chief dangers of meth is that it has a highly toxic effect. High doses can elevate body temperatures to critical, often lethal levels. It might also cause sudden, dangerous, and extreme convulsions.
