Which are more dangerous depressants or stimulants?

Both depressants and stimulants can be dangerous, but their risks differ. Depressants, like alcohol and benzodiazepines, can lead to respiratory failure and overdose, especially when combined with other substances. Stimulants, such as cocaine and methamphetamine, can cause cardiovascular issues and increase the risk of heart attack or stroke. The danger often depends on the specific substance, dosage, and individual health factors.
