This was an epidemiological study and epidemiological studies can NEVER prove causation. They can only prove correlation, and correlation does NOT prove causation. A demonstrable mechanism, operating at the cellular level, is required. Demonstration of a clear dose-response relationship is also required. Only when those requirements have been met, will there be grounds to claim causation.

this is very disturbing and seems wrong, I'm 38 (with an IQ of 137) and a pot smoker since 13... on and off, but very heavy on the last 15 years... used to drink, but not for a while.

You can say I'm addicted to weed, but I go on vacations, long/short trips without it no problems. Every now and then it gets boring and I stop using it.

I do not have health problems, other than seasonal flu's. No headaches. No psychosys. 

I'm a hard worker, with stable job and finances. 

I have a partner (heterosexual, not that matters) and we do well.

am I just an exception?
