What manner of death is classified as an intentional drug overdose?

The manner of death classified as an intentional drug overdose is suicide. This classification is primarily based on the intention behind the actions leading to the overdose. In cases of suicide, the individual deliberately takes an excessive dosage of drugs with the intention to end their life. This intentionality is a critical aspect of differentiating suicide from other manners of death.

In contrast, homicide would involve a drug overdose administered by another person intending to cause harm or death. Accidental death might occur when an individual consumes drugs not realizing that they are taking an overdose, which lacks the intention to die. Natural death pertains to deaths resulting from disease or natural causes and is not applicable in cases of drug abuse or overdose scenarios.

Thus, in the context of drug overdoses, if it is determined that the overdose was intentional, it is classified as suicide, reflecting the individual's awareness and desire to end their life through that means.
