I haven’t written about the legalization of marijuana very much on NBS, but I have long been in favor of it. No study has ever established a causative link between marijuana and cancer (or any other major disease), and I don’t think it is particularly detrimental to society to allow people to smoke it. Moreover, criminalizing the plant only creates an atmosphere of violence and real crime, not to mention the creation of criminals from the non-criminals who get locked up for using or selling it. That said, however, some new evidence has forced me to reel my views back at least a little:
Researchers found persistent users of the drug, who started smoking it at school, had lower IQ scores as adults.
They were also significantly more likely to have attention and memory problems in later life, than their peers who abstained.
Furthermore, those who started as teenagers and used it heavily, but quit as adults, did not regain their full mental powers, found academics at King’s College London and Duke University in the US.
Those who started later in life – usually during their college years – also experienced a drop in IQ, but were able to recover relatively soon after quitting.
I don’t particularly have a horse in this race – believe it or not, I do not smoke anything and I have no desire to ever start – but I’ve seen plenty of promising people lose track of their lives because of weed. Some have gotten things back on track and the others certainly could do the same, but that’s lost time and productivity. I think the world would simply be a better place with legalization and regulation of marijuana, especially where minors are concerned – and there’s good evidence behind that view.
