Regardless of research reviewed, smoking marijuana caused brain damage in all subjects and that brain damage becomes permanent if smoking marijuana started in the teenage years. Sometimes the brain could bounce back, sometimes not……but the brain damage was constant across the board, regardless of how much was smoked daily. Heavy users experienced massive brain damage, including an entire list of neurological and mental health problems. The Canadian Government (ruling families who control the political acting performers down here on the Canadian human farm) have unilaterally made marijuana legal throughout the country. People who are aware of what’s really happening behind the scenes aren’t confused at all about the legalization of another brain damaging substance for the slave class. May the odds be ever in your favor.
