Donald Trump Warning: US President Donald Trump has signed an executive order easing restrictions on medical marijuana while delivering a stern warning to young Americans: “Don’t take drugs!” Trump emphasised that the move does not legalise recreational use but recognises marijuana’s potential in carefully administered medical applications, including as a substitute for addictive painkillers. Speaking to the press, Trump highlighted the dangers of illegal and unregulated drugs and urged youth to stay away unless prescribed by a doctor.
