The use of a torch in dabbing is too extra. Using a blow torch on glass seems too much like smoking crack or meth. No offense to people who smoke crack or meth. Just, having a dab rig feels like a chemistry project.

Smoking weed feels better outside. A vape pen is portable and easy to conceal. A small glass pipe is easy to keep in your pocket with a lighter. Joints and blunts are also very portable and entirely disposable. If you wanted to do dabs outside, you'd have to go to a park or something and keep the rig in a backpack, and you'd have to keep water in a bottle, and carry a torch, and other assorted dabbing tools.
