no its not fine at all my advise just change the juice to free base nicotine with 6mg or 3 mg nic bec the salt nic is really heavy on the 0.5 pod ,i migh be wrong but this is my expericene just check and tell me i used to use the salt nic before and i tried the free base 12 mg and it was really harsh so best thing is 6mg .
but direct lung with salt nic is not good at all for you
