For a sad example lets say a man buys cocaine from a new guy since his buddy got locked up and does the same amount as he's used to. Completely unaware 30% was crushed fentanyl and 15% was methamphetamines, as his friend watches him curl over in pain and vomit he just stands not knowing whether to call the police or take him to the hospital, freaking out now worried for his life making his heart race now he didn't know what to say to the police or nurses where to ditch the drugs making him less likely to live. This is a very terrible reality and the good samaritan act does help quite a bit it still leaves so many risks.
