The most addictive drug can vary by year, but they always seem to be the same drugs at the top of the list. The consistent top drug is heroin. The reason why heroin is so addictive is that it affects the body and the mind.
The drug releases dopamine in a method more than the body can produce it. With this, if a person withdrawals from heroin, it will take the body a while before it is able to recover and produce its own dopamine again. Even after heroin, this can cause a number of health issues such as depression and pain to the body.
