The drug that killed Sydney teenager Henry Kwan was not "synthetic LSD" but something else that has not yet been included on any banned products list, the Eros Association claims.

Misinformation and ignorance are driving the debate about drugs, says Eros Association CEO Fiona Patten, who has been advocating for retailers of the products.

Henry Kwan: died after jumping from a balcony.

She said the drug, which caused 17-year-old Henry to think he could fly when he jumped off a balcony earlier this month, is a new product called NBOMe.

"It's clearly a dangerous drug and yet it has not been included on any of the banned lists," Ms Patten said in a statement.
