From what would we do without them Scientists:

Teenagers who regularly smoke cannabis are putting themselves at risk of permanently damaging their intelligence, according to a landmark study.

They were also significantly more likely to have attention and memory problems in later life, than their peers who abstained.

Heavy use of cannabis also correlated with users' tendency to repeat themselves.

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.
