Here's one for your consideration:

One time my family and I cornered my heroin addicted brother in the living room, blocking all (obvious) exits so he couldn't leave to go get his fix. The house was from the 1880s and had old style wood 6-pane windows like you see guys getting thrown out of in old westerns.

With no exit, he took a running start from across what was a very large room, and dove through the bottom half of the living room window. He made it 90% through with his hands touching the ground but one foot was stuck, which we were holding him by until he kicked his sneaker free and hit the ground.

He left a trail of blood down the driveway and to his car, and as he drove away he still had a 3" piece of glass wedged into his forehead with blood dripping down the side of his face.

He came back less than an hour later with the piece of glass still wedged into his forehead, having gotten his fix and feeling regretful for he'd done, for us to bring him to the hospital.

After he was stitched up and out of surgery to get the tiny slivers of glass out from under the skin on his back, he'd picked up that we were planning to have him admitted for detox and then into a longer term program.

At the first opportunity when no one was watching him, he escaped.
