| Treatment protocol |
To measure methylation at approximately 850,000 single CpG sites across the genome, we used Illumina’s Infinium Human Methylation 850k BeadChip on bisulfite-treated samples. 0.85-1.00 µg DNA were bisulfite converted using the Zymo EZ DNA Methylation kit (Zymo Research, Orange, CA). Each conversion assay included a commercially available positive and negative control sample.

| Extraction protocol |
Bisulfite converted samples formed the input for the Illumina Infinium Methylation assay using the Human Methylation 850k BeadChips (Illumina Inc, San Diego, CA).

| Label |
Cy3, Cy5
|
| Label protocol |
The labeling, hybridization, and scanning procedures were performed on the Illumina IScan system in the University of Colorado Genomics Core.

|
| Scan protocol |
The labeling, hybridization, and scanning procedures were performed on the Illumina IScan system in the University of Colorado Genomics Core. This analysis was performed in 11 adolescents who self-identified as vaping in the last 6 months and 36 who had not. All samples were assayed once (no technical replicates) with 6 arrays (8 samples per array) performed in 1 batch.

| Description |
Nasal-epithelial Tissue Swab
|
| Data processing |
Samples were evaluated for a low mean-intensity to identify potential outliers with low-quality methylation values.
probes were removed due to non-unique mapping, influence by SNPs, or by having a detection p-value > 0.05 in at least 10% of samples.
Background subtraction using normal-exponential deconvolution using out-of-band probes (noob) to make Type I and Type II probes comparable
BMIQ normalization was considered a priori due to a concern for lack of within-array normalization as interpreted from diagnostic plots.
A non-linear dye bias correction was used to make the red and green signal intensities (Type-I) more comparable
