Its a paid bullcheet study on pot that doesn't show that it hinders the ability to learn or add to short term memory... Anyone smoking some quality pot doesn't have much luck recalling what they read when they were high... So if the short term memory is muted then there is no transference to longer term memory... Kids in Clorado will be getting their hands on pot at a higher rate than kids of other states now... You watch the drop out rate soar by 10% by 2015 and up to 25% thru 2017... Well, at least its a small state to use a testing lab to confirm what most already know... Colorado will go back to No pot for recreational use to avoid losing FED school funding by 2016...LJ
