As someone who was physically dependent on benzos, heroin, and speed, you 100% can get addicted to cannabis. I wouldn't say it was any easier to quit for me than any other drug. The experience was different but the effects on my life were broadly similar.

If not addiction, what would you call spending money, time and health you can't afford on something? I only managed to quit about five months ago and I've already lost 18 kg in body weight and saved over £2,000. If that's not addiction I don't know what is.
