Interessant artikkel på BBC.
Studien tok for seg 1000 mennesker fra de var unge og før de hadde begynt a røyke cannabis. Konklusjonen var at cannabismissbruk fra før 18 års kan ha en permanent effekt på en persons mentale kapasitet. Som da ikke går over etter lang tid vek fra stoffet. Da snakker vi ikke sporadisk bruk, men kronisk bruk over lengre perioder. Jeg skal på jobb nå, men her er utdrag fra BBC-artikkelen. Linken er ovenfor.

The more that people smoked, the greater the loss in IQ.

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

The effect was most marked in those who started smoking cannabis as adolescents.
For example, researchers found that individuals who started using cannabis in adolescence and then carried on using it for years showed an average eight-point IQ decline.
Stopping or reducing cannabis use failed to fully restore the lost IQ.
