for most marijuana consumers.......be they medical or recreational......it is like beer or wine.....most needs can be made right at home.....
....and with all the 'bad guys' who presently supply the black market with marijuana.....they will get very wealthy by going legitimate......as did the alcohol/beer/wine suppliers following PROHIBITION....if that is what they want to do

EITHER WAY.....legalization will free up hundreds of thousands of man-hours of police..court...and corrections  resources...

The problem is.........tests today will only indicate if someone has consumed marijuana in the last six weeks......tests do not indicate if one is under the influence of marijuana.....

Not that it matters......marijuana does not impair driving..,.as does alcohol nor hard drugs......Canadian drivers have been driving on the same roads as marijuana users since the sixties.....no problem
