Chronic non-neurological toxicity from volatile substance abuse

Area of Science:

• Toxicology
• Environmental Health
• Public Health

Background:

• Chronic non-neurological toxicity from volatile substance abuse (VSA) is primarily documented through case reports.
• Assessing VSA toxicity is complex due to variations in exposure conditions and abused product composition.
• Clinically apparent chronic organ toxicity in young, healthy individuals from VSA requires severe manifestations, potentially explaining low reporting rates.

Purpose of the Study:

• To review the evidence for chronic non-neurological toxicity associated with volatile substance abuse.
• To identify specific solvents linked to permanent organ damage in VSA.
• To discuss factors influencing the reporting and clinical presentation of VSA-related toxicity.

Main Methods:

• Literature review of case reports on chronic volatile substance abuse.
• Analysis of factors affecting toxicity assessment, including exposure variability and product composition.
• Examination of clinical presentation of organ damage in VSA cases.

Main Results:

• Toluene, 1,1,1-trichloroethane, and trichloroethylene are identified as solvents capable of causing permanent kidney, liver, heart, and lung damage.
• The severity of organ damage from VSA may be underestimated due to the need for gross pathology to be clinically apparent in young, healthy populations.

Conclusions:

• Certain volatile organic compounds, including toluene and chlorinated hydrocarbons, pose significant risks for permanent organ damage in substance abusers.
• Further research is needed to fully elucidate the chronic toxicity profile of VSA, considering the limitations of current evidence and reporting.
