I am certain that you are on to something. I don't have any links right now... but there have been numerous studies that have shown that pot smoke causes chromosome damage. There have also been studies that have shown that children of mothers who are pot smokers have a much higher incidence of autoimmune disorders such as Lupus.
I know so many people who have had problems related to their pot smoking both mental and physical. They will acknowledge that they have a problem, but they will not give up the pot under any circumstances. Yet we are told by activists that it is not addictive.
So is it the smoking that is the problem, as opposed to, say, eating it in a brownie?
I have read there’s a lot more tar in pot than tobacco. I also wonder about all the chemical fertilizers that commercial pot growers drench their plants with in an attempt to boost yield.
