Weed phyiscally can NOT make you dumb. The only cells the THC kill are called "Glioma"

These cells are the ONLY brain cells to grow tumours, resulting in death and the brain doesnt use them for anything. They are there to kill us.

If you smoke dope consistantly, you most pobably will not ever get any type of tumour, and for that matter, cancer.

It does make sense, it happens to me all the time.

Its a VERY good theory. Tell your dad what i said above. People need to know the FACTS. Not what the TV and papers tell them.
