The legalisation debate has been going for so long that I became aware of the (colloquial?) link between its use and paranoia some 20+ years ago. Certainly enough to scare me off using it.
I was surprised to learn, recently, that skunk, which I thought was something new, has been sold in the UK for about 20 years too.
The article specifies people in their 20s and younger. Psychosis is a distinct from paranoia and we'll call it a 'new symptom', for the sake of argument. So, either we must postulate
i) that skunk brings on psychosis in a timespan as short as two or three years' exposure (psychotic teens) or
ii) their exposure began in the womb and they consumed it passively until their parents straightened out of using it in the family home. Smoking their own took their ligetime exposure past a much longer threshold, say 15-20 years.
The Matthew Parris and Jon Snow accounts report disturbing experiences from a single exposure.
If so, I would like to read a chemical analysis of what they tried versus what MS patients take as an analgesic. Is skunk cut with addictive agents, like opioids, or something?
