FYI............I appreciate no confrontation, but, it is the opinion of the members of the medical forum that any use of capsaicin in e-liquid is harmful at any level. It is an irritant and could permanently harm the tissues of the bronchials and the upper airways. It is the active substance in pepper spray and is a food product but has been deemed unsafe to be used in tiny amounts during research to induce a cough reflex to analyze the effectiveness of cough remedies. This subject has been discussed at length with Respiratory therapists, nurses,EMTs and Physicians that vape and none would choose to use it. It is considered harmful at any dose.
Please don't shoot the messenger.....I am reporting the consensus of the medical forums discussion.
In my DIY, I achieve increased throat hit with PGA (which some medical professionals disagree with as well) ginger, clove, horehound, horchata and with higher PG or nicotine.Some DIY flavors should not have a throat hit. For instance, have you ever gotten a throat hit when eating a blueberry crumble? How about a green tea? I have also used a product from FA called smoke. It is a smokey flavor which pretends to be a flavor in your combustion which does cause the throat to hit. IDK why, perhaps a placebo effect.
