pot DOES do damage there is no denying it, the argument of legalization is that it does less damage than a lot of things which are legal. there isn't a doctor in the world who can say alcohol has a good feature besides the enhanced social abilities after having a drink.....too much will inhibit the ability though. i bet that playing with a computer all day is worse for your eyes than smoking a joint is for your lungs.... should TV and computers be illegal? nah.
i think the solution would be regulated sort of...... pot being legal BUT you cannot grow it......that would prevent the problem of a power crisis.
legalization would be good because it takes the illegal factor out of it......people who sell weed are criminals, SOME of those dealers also sell harder things like acid, coke, heroine and that other one that i want to call PHP but i know that's the wrong name......hmmmm
making weed legal would stop regular everyday people from becoming assosiated with criminals.
in the days of prohibition, people who bought booze were actually becoming assosiated with the mafia that is NOT good.
