what i used to do when i was in high school was made my version of this.
1. get a toilet paper/paper towel/wrapping paper cardboard tube and a box of good dryer sheets
2. rubberband 2/3 sheets on the end, and make sure to do it tight!
3. Stuff the rest of the tube with sheets
4. Take a hit
5. Blow through the open end of the tube, and out comes flowery freshness
but always do this somewhere where you can open a window as it still has a lingering effect sometimes
