"I legitimately believe Elon Musk may be going mad," writes Seth Abramson on an X (formerly Twitter) post. Abramson is Elon Musk's biographer, and has claimed that Musk's mental health and decision-making has been degrading. He warned that Musk's influence and actions, could be a threat for the United States. The X post further read, "I'm a Musk biographer who has been tracking his online behavior for the last two years- and given that he's admitted to all of mental illness, heavy drug use, and crippling stress, it is now reasonable to fear he is deeply unwell." He also claimed that Musk's private struggles are not the cause of concern, but the impact it has on public, may have grave consequences. He wrote, "His holdings across many civilization essential industries and the fact that he's the incoming POTUS mean that his madness and increasing incitement of violence endanger us all."In December 2022, after Musk faced angry boos at Dave Chappelle's San Francisco show, Abramson claimed that even then too Musk "suffered a mental breakdown". Effects of Drug Use On Mental HealthAs per the National Institute of Mental Health, a person who is unable to control their use of drugs, alcohol or medication, may suffer substance use disorder (SUD), however the good news is that it is a treatable mental disorder. People with SUD may have other mental health disorders too, which include anxiety disorders, depression, attention-deficit hyperactivity disorder (ADHD), bipolar disorder, personality disorders, and schizophrenia, to name a few. Some people may have both SUD and an existing mental disorder, however it does not mean that one cause the other. Studies show that people with pre-existing mental disorder order, may use drugs or alcohol as a form of self-medication. While some drugs may temporarily help with some symptoms, in the longer run, it gets worse. Substance use may trigger changes in brain structure and function that make a person more likely to develop a mental disorder.Also Read: What Are The Most Abused Drugs In The US?Furthermore, the UK-based Mental Health Foundation states that stimulant drugs can make you feel depressed, anxious, and even paranoid.
