I understand the constraints and the arguments against it, but personally i feel that marijuana should be a free drug due to its merits compared to other "pastimes"...
1. it is not a lethal drug. Overdosing on it would require inhuman effort... it's LD50 is even lower than nicotine!
2. getting high on it makes you passive, while getting drunk on alcohol or adrenal-pumping drugs may make you physically aggressive. I know this first hand, i mean the only thing you want to do after smoking some weed would probably to eat and/or sleep... Sure you shouldn't drive, but it's the same thing as eating cold medication...
3. it's not addictive. I've used it. No withdrawals etc, no arrhythmia, no elevated blood pressure or adrenaline levels. I personally know people who have a harder time trying to quit cigs... they use ganja occasionally without ever being addicted to it. No rage when there's none etc...
again, i know that it should be consumed with moderation due to how it may lead you to a false level of comfort and render you less productive, but personally i feel that it's just a fun smoke every once in a while.
I believe that age is only slightly relevant to maturity, so imho putting an age limit on it is balderdash...
as for people who are indeed in pain, if it allows them allay those feelings, then i believe by all means they should be allowed access to it.
I don't live in the US, but looking at headlines and how the general culture is portrayed, i would say that ganja is the least dangerous substance there is. I mean those pharmaceutical drugs have proven to be more ruinous to people's lives than ganja... seriously looking at the history of ganja, cigs, and drug use (starting with opium and it's derivative), who wouldn't think that it's all these medical and tobacco MNC's doing?
all in all, if it improves your quality of life, then why not?
It goes without saying that it would be better to forgo all the above altogether, but compared to tobacco and alcohol, ganja is chemically proven to be less ruinous for you...
