Welcome back, @randomtoker! Here's a present for you - the drip tip you're looking for. Agree with most of what you say. What volume of PG are you inhaling each day? Do you do lung hits? Seems like that's the down-side. Many find it irritating and controversy over health effects continues. And flavors. With almost all flavors, at least some components present concerns when heated or inhaled - in any amount. This is coming from the Flavor and Extract Manufacturers Association (pdf), an industry organization that promotes flavor use. The other components aren't necessarily better, most just haven't been tested. Concerned because you seem like a young, healthy person. Personally, use flavored e-liquid daily - too old to care about developing lung cancer or COPD in twenty years. Just started dabbling in cannabis-derived terpenes. Very impressed with effects. Only tried one that's mainly myrcene and linalool for a sedating effect. Don't know where it's going, just wanted to satisfy curiosity. Look forward to your future posts!
