Toxicological Aspects Associated with Consumption from Electronic Nicotine Delivery System (ENDS): Focus on Heavy...

Area of Science:

• Toxicology
• Environmental Health
• Public Health

Background:

• Tobacco smoking is a leading global cause of preventable death.
• Electronic Nicotine Delivery Systems (ENDSs) are increasingly used for smoking cessation.
• ENDSs include liquid e-cigarettes (e-cigs) and heated tobacco products (HTPs).

Purpose of the Study:

• To review the toxicological aspects of heavy metal exposure from ENDS consumption.
• To focus on the carcinogenic risk posed by heavy metals found in ENDSs.
• To inform public health strategies regarding ENDS safety.

Main Methods:

• Literature review of existing studies on heavy metals in ENDSs.
• Analysis of toxicological data related to heavy metal exposure.
• Assessment of carcinogenesis risk from identified metals.

Main Results:

• Heavy metals such as arsenic, cadmium, chromium, nickel, copper, and lead have been detected in ENDS.
• These metals can migrate from heating elements or be adsorbed from tobacco.
• Evidence indicates potential health risks, including cancer, from exposure.

Conclusions:

• Heavy metal contamination in ENDSs presents a significant toxicological concern.
• Further research is needed to fully understand the long-term health effects, particularly cancer risks.
• Regulatory oversight and consumer awareness regarding ENDS safety are crucial.
