From: Cannabis smoking is associated with persistent epigenome-wide disruptions despite smoking cessation
Differentially methylated positions (DMPs) associated with cannabis smoking. Volcano plots are shown for significant DMPs associated with a former cannabis smoking and b current cannabis smoking with never smoking status as the reference group. Compared to never smoking, hypomethylated DMPs are shown in blue and hypermethylated DMPs are shown in red. The x-axis represents the effect size for each CpG tested, where 0 represents 0% difference in methylation between groups, and 1 represents a 100% methylation difference
