That’s true, avoidance is best.
I attended a rather privileged liberal arts university in America in the 1970s where hippie culture was rampant and while there was a lot of pot around the campus, there were also plenty of people, myself included, who had nothing to do with drug culture but were certainly into all the other aspects of hippiedom.
My girlfriend at the time was quite into pot culture, but she respected my leanings and never pressured me at all. And of course I respected her lifestyle too. Really nice girl - a very bohemian theatre type. Works in a bank now...
