I think that this study will pretty much end the discussion of legalized marijuana because there is no way to shield children from the effects of second hand smoke.
Ive been wondering what effect other drugs have on developing minds, if marijuana can cause an 8 point drop in IQ. Eight points is a lot, when some of these kids are in double digits to begin with.
Yes it does sound like a lot. Attributing the same efffect to "second hand smoke" sounds insane.
It doesn’t have to be the “same effect”. Any drop in IQ is significant and if a child is exposed to second hand smoke from marijuana on a daily basis, the child would be impacted.
How many times have you joked about getting high just walking in a room full of smoke or standing near a field of marijuana that was being burned by authorities?
