Dr. Ben Romoli, a neuroscientist studying drug addiction, explains why opioids like heroin and painkillers cause so many overdose deaths; why stimulants like Adderall, cocaine, or meth put your heart at risk; and why depressants like alcohol and benzodiazepines can cause blackouts when you're using and seizures when you quit.
