If you are talking about the glass tube in the ALP then yes sir my good man you can most certainly do this.

Glass is great at making the ALP taste amazing but it's a double-edged sword. It's a super neutral compound so it doesn't interact with all that delicious vapor but it is really good at cooling things. That goo that's stuck to the glass is just vapor that condensed too quickly and didn't make it to your lungs. After a few uses, the deposits build up and ... voila... it's concentrated cannabinoids or just a concentrate to generalize.
Heat it with heavy cream or half and half (requires fat to absorb the cannabinoids) and keep it under a boil until all that yummy amber goo dissolves in the liquid. Then you can add it to whatever you like! Be warned though, the effects are like an edible so they take time to take effect and they can be really strong depending on how much sticky goodness you had on the stem. Enjoy!
Edit: you could also just scrape off what you can with a tool and add some to a regular bowl in a weed/resin/weed sandwich or on a concentrate pad. It's the gift that keeps on giving!
