Ex-smoker, vaper here
The asshats that billow out massive clouds of funk need to stop. Number of times I've been told to stop vaping: 0. Reason? I don't billow stupid clouds all the time, nor do I vape pungent chemically funk. Number of smoke alarms I've set off: also 0. Reason? See above.
Be courteous, folks. Don't vape indoors if anyone in the room isn't okay with it; you're still exposing people to nicotine and glycols.
