Elon Musk, the CEO of Tesla, announced on Thursday that he will soon buy Coca-Cola to bring the 'cocaine' back into the company, only days after claiming a 100% share in Twitter. Elon Musk, the billionaire, appears to be on another adventure. Musk's recent tweet about Coca-Cola is suddenly going viral, after creating a stir around his deal and his emphasis on free speech. 'Next I'm buying Coca-Cola to put the cocaine back in,' Musk tweeted on Thursday morning. This is in reference to the use of coca leaves in the 1980s to make Coca-Cola, which was a common element in cocaine synthesis. Musk is renowned for spewing out ideas, often jokingly, on his Twitter feed. His tweets frequently ignite disputes on a variety of topics, including the polarising issue of free speech.
