Sorry, but could you point out what is not true. It is more potent and it is addictive. Just because it is not as addictive as some drugs like nicotine or cocaine, does not mean it is not addictive.
If you mean addictive like food and sex are addictive, i.e. "psychologically addictive", then sure. But so is anything fun.
But more potent? No. The good stuff was always around.
Masturbation, Voting Democrat, and gambling do not rely on external chemistry, yet seem to form persistant habits.
The first two, of course, are syngergistic...
There's absolutely no physical addicitive component to pot (unlike nicotene or alcohol).
