Would licking someone's bare soles after they turn black from an old seal coated parking lot have long term health consequences?

Licking someone's bare soles, especially if they have been in contact with an old seal-coated parking lot, poses significant health risks. Sealant products can contain harmful chemicals, including polycyclic aromatic hydrocarbons (PAHs), which may be toxic and potentially carcinogenic. Ingesting or exposing your mouth and mucous membranes to these substances can lead to a range of health issues, from gastrointestinal problems to chemical exposure risks. Long-term health consequences could theoretically arise from repeated exposure to such harmful substances. It’s important to avoid behaviors that pose health risks and to prioritize safety and hygiene. If you're concerned about a specific situation or exposure, consulting a healthcare professional would be advisable. Update (2025-09-04): Licking someone's bare soles, especially if they've been exposed to sealant materials from a parking lot, could potentially expose you to harmful chemicals and toxins. Sealants can contain substances like polycyclic aromatic hydrocarbons (PAHs), which can be harmful if ingested or absorbed through the skin. The potential health risks from such exposure may include respiratory issues, skin irritation, or other toxic effects, depending on the specific chemicals involved and the amount of exposure. On the other hand, using smokeless tobacco products like dip carries its own set of health risks, including nicotine addiction, increased risk of mouth and throat cancers, gum disease, and cardiovascular issues. Comparing the long-term consequences of these two activities is challenging due to the different types of risks involved. Both have potential health risks, but the specific outcomes would depend on the amount and duration of exposure, individual health conditions, and other factors. Ultimately, both actions are not advisable for health reasons. If you have concerns about exposure to harmful materials or tobacco use, it's best to consult with a healthcare professional.
