Cannabis, opioids and the gateway hypothesis with Jack Wilson

Cannabis, opioids and the gateway hypothesis with Jack Wilson

Ever wondered if smoking cannabis could lead you down a path to opioid addiction? Jack Wilson and Rob Calder tackle this burning question in this episode of 'Addiction Audio'. Jack shares insights from his recent systematic review and meta-analysis, exploring whether cannabis use increases the likelihood of later life opioid use or opioid use disorders. The gateway hypothesis, which suggests that cannabis acts as a stepping stone to harder drugs, has influenced policy for years.

But how solid is the evidence behind it? Jack and Rob dive into the limitations of existing studies, pointing out that many are of low quality and often lump opioids together with other illicit drugs. Interestingly, three of the six studies reviewed were twin studies, suggesting that genetic factors might play a significant role in whether someone transitions from cannabis to opioids.

They also discuss the characteristics of cannabis users and how understanding these traits can help identify those at higher risk of moving on to opioid use. Publication bias remains a concern, particularly in systematic reviews like Jack's. The episode wraps up with a look at Jack's future research plans, aiming to better understand how cannabis impacts those already dealing with opioid use disorders.

If you're curious about the complex relationship between cannabis and opioids, this episode offers a nuanced perspective that cuts through the hype and gets to the heart of the science.
