We probably shouldn’t try and get mad at each other, but just argue sensibly (if possible ), so I will do my best. I admit that saying “thanks for the article” was sarcastic and uncalled for and I apologize.
I do try and interpret things as agreeing with my perspective, but now and then it just can’t work and I have to change my opinion. This is not one of those cases.
I realize that -5+5=0, my point is that over 10 years, if someone uses marijuana for 5 of them, then 5 years later they finally are back at where they were 10 years ago, IQ wise. Now that I look at the numbers again, my concept was right but bmy numbers were wrong.
Lets say someone has a 100 IQ, well, if they use marijuana for 5 years for five or more days a week, according to the article they will have an IQ of (sorry, I was very wrong last time, it was approx. 4 IQ points less per year, so then: 4 IQ points x 5 years = 20 IQ points) 80. Now everyone around them (assuming they are non-users with IQs of 100) has been progressing at 2.6 (approx. 3) IQ points per year. So when the marijuana user has an IQ of 100, everyone else will have an IQ of (100+(35))=115. Now even if the user quits, five years later they will have an IQ of (80+(45))=110 (3.5 approx 4 points per year for former users), and everyone around them will have an IQ of (115+(3*5))=130.
So, according to the article, if you start using marijuana around age 12 (only age group tested), for five years, then you stop at age 17, at age 17 you will be 35 IQ points less intelligent than your non-user friends. Then, if you stop for the same amount of time that you had been using, five year, you will end up at age 22 except now you are 20 IQ points less intelligent than your non-user friends.
Please correct me if I am wrong.
