LAST NIGHT, CHANNEL 4 aired a live programme on the affects of cannabis on users.

The show was the culmination of two years of work by Professor Val Curran which involved getting around 20 volunteers to try skunk, hash and a placebo at different times.

Drugs Live was all over Twitter last night and is still trending in Ireland. So, what was all the fuss about? Here are some of the highlights:

We already knew it was coming, but watching Jon Snow stoned off his face was still brilliant

“By the time I was completely stoned I felt utterly bereft. I felt as if my soul had been wrenched from my body,” the presenter has said a few weeks ago.

We found out former royal correspondent Jennie Bond took part in the trial. WHAT WOULD THE QUEEN SAY?

She also revealed she “smoked quite a lot of weed” in college and she found it pretty beneficial because it made her so relaxed. Jennie got involved in the trial because she was curious to see what was so different about the types of cannabis people are smoking nowadays.

He said he had patients whose lives had been destroyed by cannabis, patients who benefited from it, and patients whose lives had been ruined by the laws around cannabis use in the UK.

Later in the programme, when he was pretty high, they laid out some snacks for him in the studio and he sat happily munching them while everyone else had a very insightful conversation about drug use.

They used the plants to explain how skunk has higher levels of THC than hash.

Hash has a more even level of THC and CBD, which protects the brain from adverse affects of the drug.

Cannabis users spoke about the benefits for them, including clarity of thought, relaxation, creative inspiration and, for this guy, “stoned sex”…

But one young man spoke of his suicidal thoughts and how he was sectioned as a result of a reliance on skunk

Since he has come off the drug, he said he feels physically and emotionally more healthy and just generally more confident in himself.

They used this massive brain to explain how skunk and hash affect people differently

Professor David Nutt used to be a top government advisor but was sacked because of his strong views that laws around cannabis were too strict in the UK.

We were told that brain activity remained the same in the trial after people had taken the placebo and after they had taken hash. When they smoked skunk, the salient network which helps people make decisions and motivates them, was significantly disrupted. This is the first time anyone has ever seen this result.

They introduced us to a grower whose disguise and warped voice made him seem unnecessarily sinister

And finally, audience members and contributors had a levelled debate about legalisation, negative impacts of skunk, health benefits, and the need for better drug education in schools

A debate that is likely to continue in the near future, both in the UK and in Ireland, where there are hugely conflicting views on cannabis.
