in #health7 years ago

  The assessment of which drugs are more addictive is not an  easy task, even for scientists. Everyone reacts differently to drugs.  

5.Nicotine

Nicotine is a potent parasympathomimetic stimulant and an alkaloid found in the nightshade family of plants. 

4.Barbiturate

A barbiturate is a drug that acts as a central nervous system  depressant, and can therefore produce a wide spectrum of effects, from  mild sedation to total anesthesia. They are also effective as  anxiolytics, hypnotics, and anticonvulsants. Barbiturates have addiction  potential, both physical and psychological. 

3.Cocaine

Cocaine, also known as coke, is a strong stimulant mostly used as a  recreational drug. In a few  seconds, cocaine floods the brain,  improving the mood. The coke is a  psychoactive substance that acts on  our nervous system.  

2.Alcohol 

Alcohol affects the brain in various ways. It turns out that he can  increase the level of dopamine in the reward center from 40 to 360  percent. Only in 2012, as many as 3 million people died as a result of  alcohol consumption. 

1.Heroin

 Heroin is a highly addictive substance. Heroin addiction is called  heroinism. Even  the first dose can lead to the emergence of mental  addiction, i.e. an  unmanageable desire to re-use, in predisposed  individuals. The  psychological dependence intensifies with the use of  successive doses  of heroin, and the physiological addiction is also  quickly generated in  the body.
