There's no comparison between weed and these other drugs. "Trying a joint or two" has no negative repercussions unless you are prone to paranoia or anxiety.
But you are describing teens who are regular users. Teens make bad decisions. Smoking marijuana every day will (can) definitely do the things they told you. Make you slow, only care about smoking, etc. The person who lost their mind either was very sensitive to some mental illness and should not have been doing any drugs, or smoked spice (NOT marijuana).
Also "government rehab" would be an absolutely fantastic thing to have for marijuana. There are tons of people with a marijuana habit who are self-medicating (and were before legalization) and one of the points of legalization is to help people NOT abuse the drugs. Unfortunately there is nothing like this where i live, even though cannabis is legal here.
Fwiw, in my experience the first ("gateway") drug that kids get into is alcohol.
