What is a common effect of depressants at high doses?

At high doses, depressants can significantly slow down the central nervous system, leading to profound effects such as sedation and decreased physiological function. One of the most serious consequences of this suppression can indeed be the induction of a coma. Coma is a state of prolonged unconsciousness where an individual is unresponsive and cannot be awakened, which can occur when the brain is excessively inhibited by substances that depress neural activity.

This effect underscores the importance of understanding the dosage and potential dangers associated with the use of depressants, as even legally prescribed medications can present serious risks. It highlights the impact that these substances can have on vital functions such as breathing and heart rate, illustrating why they must be used with caution.
