I thought I had my snuffing technique down pretty well. Toasts…easy peasy, scotches…rarely a cough. Today I was particularly congested so I decided to try some Afrin Decongestant I had laying around. It worked great & after 5 mins. the congestion was gone. I grabbed some 3 Thistles Strong & snuffed the way I normally would. It nearly blew the top of my head off. I think all of it went straight into my sinuses. Just a warning that if you use a strong decongestant be extra careful how you snuff.
There has been a few times this summer while I was working outside in the high 90 degree weather where I was sweating my ass off and took a break to snuff. Did my usual pinch and had the same outcome. Straight to my brain! I learned quick to adjust my pinch.
