I don’t smoke either but I use jet lighters for all sorts of things from gear maintenance to soldering, they’re super handy!
As long as it’s not clogged, try completely purging your lighter, then refilling it. The pressure is probably off. I usually do this by holding the plunger down with a rubber band and letting it off gas until it’s empty.
If it is clogged, consider using higher quality butane: This can eliminate clogs in the future.
