27 Aug Institute of Psychiatry at Kings College London Confirms Cannabis Is Safe For Adults


New Study Of NZ Teens Shows Cannabis Reduces IQ.

It started to appear early this morning and has been variously attributed to the University of Queensland in Australia and Duke University in Durham, Carolina, USA. It concerns a study of 1000 people in New Zealand over a period of 25 years, from age 13 to age 38. The headline claim is that “The most persistent adolescent-onset cannabis users evidenced an average eight-point IQ decline from childhood to adulthood”.

I haven’t been able to establish an original source yet but you can bet that this is going to hit the mainstream headlines very soon. The BBC has already called me about a possible radio interview tomorrow.

Existing sources are: Herald.ie MSN NZ

So what does it mean?

It’s nothing new really. We already know that cannabis as with any psychoactive substance can be harmful to the developing brain. I’m pretty confident that equivalent results with alcohol used from age 13 would be much more damaging.

The vital and important point about this is that it sheds light, yet again, on the appallingly irresponsible policy of prohibition. Our governments are failing entirely to provide any protection to our children against cannabis dealers. All the evidence is that where cannabis is legally available to adults through a properly regulated system, use by children falls and age at first use increases.

However, one exciting quote has emerged in early reports. This is a very important nugget of information that highlights the truth about cannabis and could prove immensely valuable to our cause:

Professor Terrie Moffitt, from the Institute of Psychiatry at King’s College London, who took part in the study, said:

“It’s such a special study that I’m fairly confident that cannabis is safe for over-18 brains, but risky for under-18 brains.”
