Drugs have a pleasure effect on the brain. Food does too. So do experiences or playing sports. Winning a sports game feels exactly the same as doing cocaine. Issue with drugs is the risk. Risk of damage to your body or your mind. But the other activities have associated risk. For example, I ski and including back country. I risk avalanches and injury. I've broken a rib and have countless other injuries. I have friends with permanent injuries and have seen deaths on the ski slope. No one says skiing is a national problem.
