What a awesome way and reason to vape! Kudos for your ingenuity
It seems to me that the issue is not who yours, but theirs.
They
perceive that what you are doing
appears as something that
might be "bad"(for brevitys sake).
I do not mean this in a derogatory way, but their ignorance (not knowing a variety of factors about your vaping) is what needs to be addressed.
Example:
A man is walking down a dark street and sees a scraggly looking man pulling a very well dressed woman backwards towards him grunting while she gasps an gags, viciously struggling to "get away", as he continues to pull her waist (struggling) towards him.
The observer thumps him over the head, "saving" her and disabling the man.
She falls on the ground, choking and dies.
Later it's found out that they had just walked out of a restaurant 1/2 a block up, and she was choking on a crust of bread she grabbed from her "doggie bag"
The "assailant" was her husband, a minister, who has worked all day doing charity mechanical work and was between haircuts.
And, of course, he was attempting to perform a Heimlich maneuver to dislodge the obstruction.
Appearances and perceptions. So much in life is gray area like the vapor in which we exhale.
So basically I would remind those of whom you speak (that think walking around with that proverbial "beam" in their eye is an appropriate fashion statement) of these nuggets of knowledge:
Do All to the Glory of God (from 1st Corinthians 10)
23 All things are lawful, but not all things are helpful. All things are lawful, but not all things build up. 24 Let no one seek his own good, but the good of his neighbor. 25 Eat whatever is sold in the meat market without raising any question on the ground of conscience. 26 For the earth is the Lords, and the fullness thereof. 27 If one of the unbelievers invites you to dinner and you are disposed to go, eat whatever is set before you without raising any question on the ground of conscience. 28 But if someone says to you, This has been offered in sacrifice, then do not eat it, for the sake of the one who informed you, and for the sake of conscience 29 I do not mean your conscience, but his. For why should my liberty be determined by someone elses conscience? 30 If I partake with thankfulness, why am I denounced because of that for which I give thanks?
But this,
this, good gentle friend speaks to the very core of worshiping "in spirit". ( Remember " the spirit giveth life" and "worship in spirit")
From
Colossians 2:
Freedom From Human Rules
16 Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day. 17 These are a shadow of the things that were to come; the reality, however, is found in Christ. 18 Do not let anyone who delights in false humility and the worship of angels disqualify you. Such a person also goes into great detail about what they have seen; they are puffed up with idle notions by their unspiritual mind. 19 They have lost connection with the head, from whom the whole body, supported and held together by its ligaments and sinews, grows as God causes it to grow.
20 Since you died with Christ to the elemental spiritual forces of this world, why, as though you still belonged to the world, do you submit to its rules: 21 Do not handle! Do not taste! Do not touch!? 22 These rules, which have to do with things that are all destined to perish with use, are based on merely human commands and teachings. 23 Such regulations indeed have an appearance of wisdom, with their self-imposed worship, their false humility and their harsh treatment of the body, but they lack any value in restraining sensual indulgence.
Vape on!
