Should school authorities impose stricter rules to fight against the problem of drugs?

Someone argued that school should impose stricter rules to fight against the problem of drugs. In my opinion, I think school should do this. Drugs are harmful to everyone that which will confuse your mental,speech also behave.These are a real cliffhanger after you take your first time.Many students or youth become a drug addict is because of their friend who is a stoner.I mean not a little amount of teenager were influenced by stoner to try at drugs. In deeded, they even share illegal drugs in their school. It really a serious problem that school authorities should stop it and lead them in a correct way.
