Members of the NIDA International Program Inhalant Working Group have published a letter in the Canadian Journal of Public Health [103(6): 473] calling for increased qualitative and quantitative research on inhalant abuse. The letter cites recent findings that inhalants are often the first substance misused by young people, use among girls is increasing, and volatile substances are being marketed in parts of Mexico with the addition of appealing odorants, such as cinnamon or coconut.
