People attending raves should be at least 16 years old, a coroner's inquest jury in Toronto recommended Thursday.
The jury also suggested drugs should not be mentioned in advertisements for the all-night parties and special permits should be required.
The inquest was called into the death of Allen Ho, a 21-year-old who died at a rave in Toronto last summer. Ho had ingested the designer drug ecstasy, then collapsed at the party, held in an underground parking garage.
Coroner Dr. Barry McLellan described Ho's death as accidental, though it did involve complications from drug use.
The jury issued 21 recommendations, among them a plea for more education about the risks of various drugs used at raves.
