Honestly, Don't worry about it,
I've been smoking for about 9Years and I puke sometimes from having one, Sometimes it's becauseI've not had one in a while (Hours or sometimes a day or two).
It happens sometimes in the morning but I've put that down to strangelybrushing my teeth.
I've never known anyone else to puke after having one but I've never really asked anyone or google it but as far as I'm aware it's nothing bad.
Hope my answer helped,
Enjoy your day,
