A descriptive study of clinical, hematological, and biochemical parameters of inhalant users seeking treatment at a tertiary care center in India.
BACKGROUND
Inhalant (or solvent) abuse is the purposeful inhalation of vapors or gases, intended to produce pleasurable psychoactive effects. There is a dearth of Indian studies on inhalant users.


OBJECTIVE
The present study aimed to describe the socio-demographic, clinical, and psychosocial characteristics of inhalant users visiting a Tertiary Care Center in North India.


METHODS
The study was a retrospective chart review for 50 inhalant users who sought treatment for the first time from the center over a period of 2 years. All patients seeking treatment for inhalant use at the center were evaluated by a psychiatrist.


RESULTS
Mean age of the sample was 17.16±4.09 years and majority comprised of children and adolescents (72.2%). There were only three girls (6%). Majority comprised of school drop-outs (82%), from lower socio-economic status (80%). Mean age of initiation of first substance was 14.13±4.27 years and inhalants were first drugs for 38%. Duration of inhalant use ranged between 1 month and 7.5 years. Use was mostly uninterrupted, and 88% were dependent users. Correction fluid was the commonest product, used by huffing or sniffing. A large majority (86%) had used at least one other substance besides inhalants, and 8% reported involvement in high-risk sexual behaviors. Comorbid psychiatric disorder was seen in 8% of sample. Positive family history was observed in 30% of the sample. The mean hemoglobin of the sample was 11.88±0.60, with low hemoglobin in 25% of users. Neutrophils, lymphocytes, eosinophils, and monocytes were elevated beyond normal in 10.8%, 6.5%, 15.2%, and 7.5%, respectively. There was no evidence of leucopenia. Bilirubin and serum glutamic pyruvic transaminase was elevated in 6.6% and 13% of inhalant users, respectively.


CONCLUSIONS
The study adds to the limited date available on the treatment-seeking inhalant users from Indian settings. There is a need to examine the pattern of inhalant use in larger samples, across multiple sites in a prospective manner.
