Opposite Effects: Methamphetamine causes activation of the central nervous system (inc heart rate and blood pressure). Heroin causes supression of the central nervous system (sedation and respiratory suppression). Both substances are highly addictive with high rates of morbidity and mortality. Due to its strong respiratory suppression, heroin is more likely to cause death. Best to avoid both entirely.
