I recently found a forgotten half-used bottle of salt nic vape juice (Yogi Salts peanut butter granola bar 35mg). After I started vaping it, I noticed some chest tightness after about 10-20 mins. This occurs even with a single drag (I normally take a 2-3 drags each time). Before this, I was consistently vaping a spearmint flavoured 25mg salt nic juice for the past month. Should I be concerned with this chest tightness at all ? The reason I'm asking is because I never had this issue before, not with this juice, nor other juices with similar flavour profiles or nic levels.
