Cannabis Evolution: Dr. Tom Freeman on THC and CBD Shifts Over Time
The key message is that cannabis products have changed substantially over the past years or so, characterised by an increase in THC and stable levels of CBD, and this raises challenges for people who manage cannabis in clinical settings.
Ever wondered how the cannabis you see today compares to what was available decades ago? Dr. Tom Freeman, director of the Addiction and Mental Health Group at the University of Bath, joins Suzi Gage to shed light on this very topic. In this episode of 'Addiction Audio', they dive into Dr. Freeman's research on the evolving THC and CBD content in cannabis products from 1970 to 2017.
Spoiler alert: THC levels have been on the rise, with herbal cannabis seeing a yearly increase and cannabis resin doubling in potency. This shift poses real challenges for clinicians trying to manage cannabis use, as the varying strength makes it tough to gauge what exactly patients are consuming. Dr. Freeman also explores the idea of standard units for THC, which could bring some much-needed clarity to the situation.
But it doesn't stop there; the conversation touches on the link between cannabis and psychosis, the impact of these changes on treating cannabis disorders, and the hurdles researchers face in this ever-evolving field. If you're curious about how these changes might affect future cannabis use and treatment, this episode is a must-listen.
