As someone who was 14 years of age at the time of the “Woodstock” pop concert which is supposed to have been a watershed,
I doubt that there were many “16-year-old pot-smoking hippy chick anti-war activists” around at that time.
Even in the sixth form, I never knew anyone who used drugs. 20-year-olds at university maybe.
Sadly, in the last twenty years, this has changed.
I can remember being in a building in a local public park and overhearing a group of children using what they called “blow”
A girl who can only have been 11 or 12 went from stone-cold sober to slurred speech “drunk” in about 2 minutes.
Later I collected evidence of both cannabis and heroin use at this site and dutifully delivered it to the local police station.
The police did nothing and shortly afterward the local community constable was awarded the MBE “for services to Youth”.
