@extinctsnakes@mastodon.social generally not holding down the button so long/not taking deep inhalations will result in less visible vapor, also
Like, those guys with the huge clouds have v. high temperature cores, and inhale a lot at once
So just taking shallow pulls is gonna help a lot too
@extinctsnakes@mastodon.social the 'big cloud' brands tend to run thick, too; they have wider barrels (so that + the higher temp means you inhale more at once)
So generally if something's big & bulky it's probably for showing off like that, with a high voltage core and large diameter inhalation. tube- Pen sized ones will have less emmissions simply by not having that hi-voltage & wide-diameter breathing tube capacity
