Charlie Sheen got into major trouble mainly because of drug use, erratic public behavior, legal issues, and conflicts at work , especially during the collapse of his run on Two and a Half Men.

What happened

  • He was widely reported to have struggled with heavy substance abuse and a very public meltdown that made headlines for years.
  • His behavior led to feud-filled fallout with the show’s production, and he was eventually fired from Two and a Half Men.
  • He also had arrests and other incidents that kept adding to his reputation for chaos.

Why it became such a big deal

  • The trouble wasn’t just one event; it was a pattern of publicly self-destructive behavior that played out in the media.
  • More recently, documentaries and articles have revisited that period as part of his “unraveling” and recovery story.

In plain English

He didn’t get in trouble for one single thing so much as for a long stretch of addiction, bad decisions, public outbursts, and professional blowups that became impossible to ignore.

TL;DR: Charlie Sheen became infamous because of addiction-related behavior, arrests, feuds, and getting fired from Two and a Half Men.
