So, let us know more about drug abuse and how they affect both physically and mentally.

Mental Affect

Drugs can affect the brain by producing chemicals that can kill many brain cells that cannot revive or rebuild themselves. When you take drugs, it creates a large amount of dopamine, giving you a feeling of pleasure. These regulate emotion and feel in your brain, giving you a sense of being high.

After a while, the brain will crave more dopamine. Thus, increasing your tolerance level. When you keep on increasing the dose after a point in time, you will not satisfy the craving. Consequently, causing damage that is both short and long-term, leading to a change in behavior and personality. It can also lead to emotional changes, like the following:

  • Increased aggression
  • Depression
  • Hallucination
  • Panic attacks
  • Anxiety
  • Paranoia
  • Impulsiveness
