coughing

Drink warm water with honey and don't be embarrassed to take smaller hits if it makes you feel more comfortable. The coughing never gets better, you either quit or just become used to it. 

Personaly I don't use bongs but if you do then try to use warm water insted of normal or cold.

It's more smoth when smoking and will make you cough less.

Personaly I find that a mint right after smoking or taking a dab helps a lot. I use "trident - frutos vermelhos" just google it and see what similar stuff you can find in ur country xoxo
