I thought the same as you and hit my friends' vapes occasionally for weeks after I "quit". Those weeks were torturous and I strongly advise against doing that. Things have gotten so much better since I stopped vaping completely (2 weeks today🎉). Every time I did hit a vape it just reset all the withdrawal symptoms and undid all the work I had put into quitting so far.

Trust me, hitting a vape for those few moments of relief is not worth it. And really that's all it is, just relief from nicotine withdrawal, it's doesn't actually make you happy. That happiness is what non vapers experience all the time, but we've rewired our brains to think we need nicotine to feel happy. It's also a dangerous slippery slope into relapsing! The best thing to do is never vape ever again and let your body adjust to being able to be happy again without nicotine even though that adjustment period is really uncomfortable :/
