Elias stood at the counter of his favorite shop, his eyes scanning the shelves for something specific. He wasn't looking for the standard throat hit that came with high propylene glycol (PG); he wanted the thick, velvety clouds that only a high liquid could provide.

"Looking for the heavy stuff?" the shopkeeper asked, pulling a bottle of 80/20 VG/PG blend from the shelf.

: High VG (70% or higher) is designed for "cloud chasing" and produces significantly more visible vapor than PG.
