My adult girl, who I recently measured at 4 feet 3 inches long and about 2000 grams could easily strangle you. I can't let her wrap entirely around my neck because when she's moving she'll tighten her muscles and grip around my windpipe, cutting off my air unintentionally just with her weight and trying to move. When she wants to stay on my arm it's definitely difficult to get her off, and if she gets herself wrapped around something and doesn't want to let go, it can be a fight to get her loose. She's pretty strong, I think...XDD but maybe it varies from snake to snake. She definitely isn't strong enough to break any bones, though. (Except maybe rodent bones!)
