Complacency is a huge downside. I'm also much less motivated to work on side projects. Not to mention the toll on the lungs. Ask Willie Nelson if you'd like anecdata about how that can play out over a lifetime. I've recently made the leap to edibles exclusively after a stint with a hot-air vaporizer (a la Volcano devices) and I now find the resin smell of smoking incredibly off-putting. The coughing, hacking, and lung stiffness that results from a bong rip even more so. Doesn't lessen the complacency, but the delay your metabolism introduces can help you get started on projects before it sets in!
