In the room, he had a laminar flow hood that used to make E-Juice in. The laminar flow hood prevents contamination of the air going over the bottles. It filters to below three microns to prevent any type of dirt or grime that may get into the bottles. He uses surgical gloves and work with needles and pipettes. The flavorings he uses are stored in amber dropper bottles with a 1ml dropper included. When he needs to make a large batch of E-liquid, he uses lab specific glass beakers and cylinders to measure accurately and consistently. Spreadsheets are used to record ratios needed for any PG/VG ratio or nicotine level. He use standard USP Kosher PG/VG and mixes down to 90% VG E-juice but normally he makes around 20% flavoring so 20% PG and 80% VG for maximum flavor; only using 90% by special request. When steeping or curing the juice he lets the bottles sit in industrial grade jewelry cleaner where the E-Liquid will become homogenous only after a few short hours. All glassware are cleaned and washed after every mixing to avoid contamination of flavors or nicotine. Needless to say, I was quite impressed with this small startup company how much he paid attention to detail and cleanliness to his craft. He is definitely a person that takes pride in his work.

"This is currently not the situation."

Furthermore, later in the paper they reinforce this point more specifically, writing: "the cross-sectional nature of our study does not allow us to identify whether most youths are initiating smoking with conventional cigarettes and then moving on to (usually dual use of) e-cigarettes or vice versa...".

Very first thing I did was a little math. I knew I didn’t want to make more than 10ml worth of E-Juice and I didn’t want the flavorings to exceed 10%; which meant I need 9ml worth of diluent or my base. Now I know a lot of vendors deal with pure nicotine and mix it themselves to cut down on costs. But this is also very dangerous as I was at home doing this in my dining room table.
