This alphabetical list contains notable people whose deaths can be reliably sourced to be the result of drug overdose or acute drug intoxication. Where sources indicate drug overdose or intoxication was only suspected to be the cause of death, this will specified in the 'notes' column. Where sources are able to indicate, deaths are specified as 'suicide', 'accidental', 'undetermined', or otherwise in the 'cause' column. Where sources do not explicitly state intent, they will be listed in this column as 'unknown'. Deaths from accidents or misadventure caused by drug overdoses or intoxication are also included on this list. Deaths from long-term effects of drugs, such as tobacco-related cancers and cirrhosis from alcohol, are not included, nor are deaths from lethal injection or euthanasia .
