just saying
That said, the chemicals themselves are unlikely to cause death. This, obviously, is not the same as "will definitely not have any unpleasant consequence".

"Coroner: Aragon High School student took LSD before falling to death in Canada"

"A 17-year-old Aragon High School student was under the influence of LSD when he plunged to his death during a trip to Canada in June with teachers and fellow classmates, according to a British Columbia coroner's report.
"Daniel Cho and two friends took the drug while they were on a bus headed from Seattle to Vancouver, British Columbia, according to the coroner. The boys were with more than 100 other Aragon students headed to Canada as part of a musical exchange program.
"When the group made a stop at a popular tourist spot called the Capilano Suspension Bridge on the evening of June 6, Cho climbed over a 4-foot-high fence and fell 100 feet into a ravine below.
"The coroner has ruled his death an accident, and Canadian police won't file any criminal charges in connection with the case."
The substance itself does not cause an "overdose" and the same is true of cannabis (at least for any ingestible amount), but it would be disingenuous to claim they have not caused deaths.
Alcohol and tobacco do kill tens of thousands of people every year. Ecstasy and LSD and Cannabis kill maybe a dozen people every year all together, and usually in combination with other drugs. Yet there are considerably fewer resources allocated to fighting alcohol and tobacco use than the latter.
